THE PROFILE-II/VERDICT-II DRUGS OF ABUSE TEST PROVIDES ONLY A PRELIMINARY ANALYTICAL TEST

RESULT. A MORE SPECIFIC ALTERNATE CHEMICAL METHOD MUST BE USED IN ORDER TO OBTAIN A

CONFIRMED ANALYTICAL RESULT. GAS CHROMATOGRAPHY/ MASS SPECTROMETRY (GC/MS), HIGH

PERFORMANCE LIQUID CHROMATOGRAPHY (HPLC) OR LIQUID CHROMATOGRAPHY/TANDEM MASS

SPECTROMETRY (LC/MS/MS) ARE THE PREFERRED CONFIRMATORY METHODS. CLINICAL CONSIDERATION AND

PROFESSIONAL JUDGMENT SHOULD BE APPLIED TO ANY DRUG OF ABUSE TEST RESULT, PARTICULARLY WHEN

PRELIMINARY POSITIVE RESULTS ARE OBTAINED.

2. SUMMARY AND EXPLANATION OF THE TEST

Qualitative PROFILE-II / VERDICT-II Drugs of Abuse screens utilize a one-step, solid-phase immunoassay technology to provide a

very rapid test requiring no instrumentation. This test may be used to screen urine samples for one or more of the following drug

classes prior to confirmatory testing:

Marijuana (THC) is a hallucinogenic drug derived from the hemp plant. Marijuana contains a number of active ingredients

collectively known as Cannabinoids.

Opiates (OPI) are a class of natural and semi-synthetic sedative narcotic drugs that include morphine, codeine and heroin.

The “Amphetamines” are a group of drugs that are central nervous system stimulants. This group includes „amphetamine‟ and

„methamphetamine‟, and related designer drugs like „3,4 Methylenedioxymethamphetamine‟, (better known as Ecstasy or MDMA a

psychoactive drug with hallucinogenic effects). The drug „Amphetamine‟ (d-amphetamine) is detected on the device only at the

(AMP) position. Both the designer drug Ectasy (MDMA) „Methylenedioxymethamphetamine‟ and methamphetamine (d-

methamphetamine) are detected on the device only at the (MAMP) position.

Cocaine (COC) is a central nervous system stimulant. Its primary metabolite is benzoylecgonine.

Phencyclidine (PCP) is a hallucinogenic drug.

Tricyclic Antidepressants (TCA) are a group of structurally related prescription drugs that are used to manage depression.

Barbiturates (BAR) are a group of structurally related prescription drugs that are used to reduce restlessness and emotional tension,

induce sleep and to treat certain convulsive disorders.

Methadone (MTD) is a synthetic opioid used clinically as a maintenance drug for opiate abusers and for pain management.

Benzodiazepines (BZO), a group of structurally related central nervous system depressants, are primarily used to reduce anxiety and

induce sleep.

Propoxyphene (PPX) is a narcotic analgesic. It‟s primary metabolite is norpropoxyphene.3

Oxycodone (Oxycontin®, Percodan®, Percocet®, etc) is a semi synthetic narcotic analgesic that is prescribed for moderately severe

pain. It is available in both standard and sustained release oral formulations. Oxycodone is metabolized to oxymorphone and

noroxycodone.

Many factors influence the length of time required for drugs to be metabolized and excreted in the urine. A variety of factors influence

the time period during which drug metabolites are detected in urine; the rate of urine production, the volume of fluid consumption, the

amount of drug taken, the urine pH, and the length of time over which drug was consumed. Drinking large volumes of liquid or using

diuretics to increase urine volume will lower the drug concentration in the urine and may decrease the detection period. Although the

detection period for these drugs varies widely depending upon the compound taken, dose and route of administration and individual

rates of metabolism, some general times have been established and are listed below.1-4, 6

The LFAS is a lateral flow strip with impregnated reagent test pads that detect specific analytes in human urine. The analytes detected

are Oxidants and Nitrites. The strip also approximates the pH and specific gravity values. Urine samples with „abnormal‟ values

should be submitted to a reference laboratory for additional testing.

Oxidants The detection is based on the oxidative activity of compounds (e.g. chromate salts and/or Bleach) that catalyze the oxidation

of an indicator by an organic hydroperoxide producing a blue/orange color. The color intensity is directly proportional to the

concentration of Oxidants present in the sample and is observed visually and compared to the color comparator chart to obtain a result.

Nitrites The test is based on the principles of the Griess reaction for the detection of Nitrites. The test pad contains an amine and a

coupling component. A red/orange colored azo compound is obtained by diazotization and subsequent coupling. The color intensity is

directly proportional to the concentration of Nitrites present in the sample and is observed visually and compared to the color

comparator chart to obtain a result.

pH The test paper contains indicators that change colors between pH 2 and pH 11. The color scale gives an approximate indication for

pH values between those levels.

Specific Gravity The test pad reacts with ions in urine to indicate concentrations from 1.000 to 1.020. The color changes range from

dark green with low ionic concentrations through green to yellow/orange in urines with high ionic concentrations. The color is

observed visually and compared to the color comparator chart to obtain an approximate result.

3. PRINCIPLES OF THE PROCEDURE

The PROFILE-II/VERDICT-II Drugs of Abuse Test is a one-step, competitive, membrane-based immunochromatographic assay. A

single urine sample can be evaluated for the presence of each of the specified classes of drug(s) in a single device. The device consists

of antibody-colloidal gold, drug-conjugates and a control line.

1. ANTIBODY-COLLOIDAL GOLD Mouse monoclonal drug antibodies were developed. Each antibody only binds drug(s) from

the drug class tested. Antibody-colloidal gold solutions were prepared by absorbing each of the individual monoclonal antibodies to

colloidal gold. The colloidal gold solutions were applied to the sample well pad in the drugs of abuse test.

2. DRUG-CONJUGATES Drug from the class tested was individually conjugated to bovine serum albumin (BSA) or IgG. Each

drug conjugate was immobilized as a line at a labeled location on the membrane strip.

3. CONTROL LINE Each test strip has anti-mouse immunoglobulin antibody immobilized as a line on the membrane at the CTRL

location on the device window. The anti-mouse immunoglobulin antibody can bind to any of the mouse antibodies coated on the

colloidal gold.

The device can be used to detect specific class(es) of drug(s) in urine because drug(s) in the urine and the drug(s) conjugated to the

protein compete to bind to the antibody-colloidal gold in a highly specific reaction. When the urine sample is placed in the sample

well(s), the dried antibody-colloidal gold on the sample pad(s) dissolves and the urine wicks up the white strips carrying the reddish-

purple antibody-colloidal gold as a solution with it.

Negative Samples

When no drug(s) is present in the urine sample, the reddish purple antibody-colloidal gold solutions migrate along the strip then binds

to the appropriate drug conjugate immobilized on the membrane. The binding of the antibody-colloidal gold to the drug conjugate

generates an easily visible reddish-purple line at each of the labeled locations in the result window. Negative results can be reported as

soon as the drug and control lines are visible.

Positive Samples

When drug(s) is present in the urine sample the antibody-colloidal gold binds to the drug(s) before it migrates along the strip. When

the antibody-colloidal gold binds to the drug(s) in the urine, it cannot bind to the drug conjugate immobilized on the membrane and no

line is generated at the drug-specific location in the result window. Read positive results at 5 minutes. The control line should be

present for the test to be valid.

CTRL Line

Each test strip has an internal procedural control. A line must form at the Control (CTRL) position in the result window to indicate

that sufficient sample was used and that the reagents are migrating properly. If a Control line does not form, the test is invalid. A

Control line forms when the antibody-colloidal gold binds to the anti-mouse immunoglobulin antibody immobilized on the membrane

at the CTRL location(s) near the top of the device window.

4. MATERIALS PROVIDED/STORAGE CONDITIONS

Storage Conditions

The kit, in its original packaging, should be stored at 2-25°C (36-77°F) until the expiration date on the label.

5. PRECAUTIONS

1. Urine specimens and all materials coming in contact with them should be handled and disposed of as if infectious and capable of

transmitting infection. Never pipette by mouth and avoid contact with broken skin.

2. Avoid cross-contamination of urine samples by using a new urine specimen container and pipette for each urine sample.

3. The device should remain in its original sealed foil pouch until ready to use. If the pouch is damaged, do not use the test.

4. Do not store the test kit at temperatures above 25°C (77°F).

5. If devices have been stored refrigerated, bring to ambient temperature (18-25°C/ 64-77°F) prior to opening foil pouch.

6. Do not use tests after the expiration date printed on the package label.

7. The drug screen portion of the device is for in vitro diagnostic use only. The LFAS strip is for Forensic/Toxicology use only.

8. If any of the lines formed are outside the arrow indicated by the drug name, the test is invalid.

6. SAMPLE COLLECTION AND PREPARATION

The urine sample should be collected in a clean glass or plastic container. Approximately 100 µL is required for each sample well.

Collection of 45 mL of urine is more than sufficient for initial and subsequent testing. No preservatives should be added. Urine may be

tested immediately following collection. The specimen may be refrigerated if testing is going to be delayed for more than a day. Urine

may be frozen for longer storage. Stored urine must be brought to ambient temperature (18 to 25°C/64 to 77°F) and mixed well to

assure a homogeneous sample prior to testing.

7. MATERIALS REQUIRED BUT NOT PROVIDED

1. External controls

2. Timer

3. A Urine collection container is not provided with the „Device Only‟ 25 Test Kit.

4. Specimen containers, external controls, disposable gloves and urine temperature strips are available from MEDTOX Diagnostics,

Inc.

8. TEST PROCEDURE

1. Open one pouch for each sample to be tested and label the device with the patient or sample identification (ID).

(You may notice a reddish-purple color in the sample well. This is normal, do not discard the test).

2. Apply 100 µl of urine to sample well as follows:

• Hold the 100 µl sample pipette by the upper bulb.

• Lower the pipette stem into the urine sample.

• Squeeze the upper bulb then release it. This motion will draw 100 µl of urine into the stem. The urine sample should reach

the top of the stem, and a drop or two should overflow into the middle bulb, if not, repeat this process.

• Dispense the urine into the sample well by squeezing the upper bulb. This will empty the stem delivering 100 µL of sample.

Excess urine in the middle bulb should remain in the bulb.

3. Repeat Step 2 for each additional sample well (for multi-strip devices).

4. Read the results at 5 minutes after application.

NOTE: For all tests except OXY, read results at 5 minutes or within 15 minutes of the sample application. The test result

after 15 minutes may not be consistent with the original reading.

For OXY only, read results at 5 minutes. The test result after 5 minutes may not be consistent with the original

reading.

9. READING THE TEST RESULTS

Negative: The appearance of both a reddish-purple Control (CTRL) line and a specific drug line indicates a negative test result. The

color intensities of the Control line and a specific drug line may not be equal; any reddish-purple line visible at 5 minutes

indicates a negative test result. Line intensity will vary from test to test.

Non-Negative: The appearance of both a reddish-purple Control (CTRL) line and the absence of a line next to a specific drug name

at 5 minutes indicates a preliminary positive test result for that drug. Occasionally a white line (line lighter than the

background of the strip) may appear next to a specific drug name. This indicates a preliminary positive test result

for that drug.

Invalid: The absence of a reddish-purple Control (CTRL) line indicates the test is invalid. The urine sample should be retested on a

new device. If the second test is also invalid, send the urine sample to a reference laboratory for additional testing.

10. INTERPRETATION OF TEST RESULTS

A NEGATIVE test result for a specific drug indicates that the sample does not contain the drug/drug metabolite above the cutoff level.

A NON-NEGATIVE test result for a specific drug indicates that the sample may contain drug/drug metabolite near or above the cutoff

level. It does not indicate the level of intoxication or the specific concentration of drug in the urine sample. Examples of Negative and

Non-Negative results are shown below.

There are other possible results depending on the drug or combination of drugs present in the urine sample.

11. QUALITY CONTROL

An internal procedural control is included on each device. A line must form at the Control (CTRL) position in the result window to

indicate that the proper sample volume was used and that the reagents are migrating properly. If a Control line does not form, the test

is considered invalid. The Control line consists of immobilized anti-mouse antibody that reacts with the antibody-colloidal gold as it

passes this region of the membrane. Formation of a visible line verifies the Control line antibody antigen reaction occurred. This line

may be considered an internal negative procedural control. In addition, if the test has been performed correctly and the device is

working properly, the background will clear such that result lines are distinct. The cleared background may be considered an internal

positive procedural control. The visible Control line (CTRL) should always be present regardless of whether drug is absent or present

in the sample.

The purpose of quality control in laboratory testing is to ensure accuracy, reliability of results and to detect errors. Because the devices

are self-contained, single use tests, traditional quality control programs do not apply. The Quality Control program MEDTOX

recommends for these non-instrumented test devices includes a combination of the internal device controls and external controls to

ensure accuracy, reliability and to detect possible errors. The on-board reactive device controls may be one aspect of the quality

program utilized by a laboratory to satisfy the daily quality control requirement established by the Laboratory Director. Another aspect

of a quality control program includes an external negative control containing no drug and a positive drug control challenging to the

assay cutoff concentration. These controls may be used to initially test each shipment of product received by the laboratory or to verify

appropriate storage conditions and long-term stability of the test reagent. To follow good laboratory practices, we recommend that the

user document the receipt of each new lot number of devices, the results of external controls performed initially and periodically

thereafter, and the results of the internal controls within each device.

It is the responsibility of each Laboratory Director to demonstrate and document the validity of the alternate QC procedure they

choose to use in their laboratory. For additional information or forensic and workplace testing requirements, users should contact and

follow the appropriate federal, state, and local guidelines. Quality control materials are available from MEDTOX and commercial

sources. Contact MEDTOX for further information.

12. LIMITATIONS OF THE PROCEDURE

1. The PROFILE-II/VERDICT-II Drugs of Abuse Test is only for use with unadulterated human urine samples. Urine samples

which are either extremely acidic (below pH 4.0) or basic (above pH 9.0) may produce erroneous results.

2. A positive result for any drug(s) does not indicate or measure intoxication. It only indicates the presence of specific drug(s) in the

urine specimen.

3. Test results interpreted after 15 minutes (after 5 minutes for OXY) may not be consistent with the original result obtained at 5

minutes.

4. The PROFILE-II/VERDICT-II Drugs of Abuse Test was not evaluated in point-of-care settings (except OXY clone was evaluated

in point-of-care settings).

5. There is a possibility that other substances and/or factors, e.g. technical or procedural errors, may interfere with the test and cause

false results.

LFAS Strip

The purpose of the adulteration strip is to screen for abnormal conditions in human urine samples, such as dilution or the addition of

drug-test interfering substances. Occasionally medications may discolor the urine, and make it difficult to read the result. When in

doubt send the urine sample to a reference laboratory for additional testing.

Oxidant

Nitrites, acting as oxidizing agents in solution, will produce a blue/green color change on the Oxidant pad.

Nitrite

Abnormal results can be caused by the presence of diagnostic or therapeutic dyes in the urine. Very high concentrations of oxidant

such as 80% bleach will produce a brown color change on the Nitrite pad.

13. EXPECTED VALUES

The Substance Abuse and Mental Health Services Administration (SAMHSA) recommends the following

screening test cutoffs:

THC 11-nor-9-carboxy-∆9-THC 50 ng/mL

OPI Morphine 2000 ng/mL

AMP Amphetamine 1000 ng/mL

COC Benzoylecgonine 300 ng/mL

PCP Phencyclidine 25 ng/mL

MAMP Methamphetamine 1000 ng/mL

There are no SAMHSA recommended screening levels for tricyclic antidepressants, benzodiazepines, methadone, barbiturates,

MDMA, propoxyphene and oxycodone and/or their metabolites.

The PROFILE-II/VERDICT-II Drugs of Abuse Test qualitatively detects THC, opiates, amphetamines, cocaine, phencyclidine,

tricyclic antidepressants, barbiturates, methadone, benzodiazepines, propoxyphene, methamphetamine/MDMA and oxycodone and/or

their metabolites as listed (See Sensitivity).

LFAS Test:

Urines that produce an abnormal result on the LFAS adulteration strip should be sent to a reference laboratory for more definitive

testing to determine if the urine may be dilute, substituted, invalid and/or adulterated.

Precision (THC, Opiates, Amphetamine, Cocaine, and PCP)

Performance around the specific cutoff for each drug was measured by testing standard drug solutions diluted in drug-free urine in

replicates of 20 each on 3 different days by 3 operators. Twenty replicates of drug-free urine were also tested on each day. At 25%

above the cutoff, the precision of each assay was as follows: THC=95%, OPI2= 96.7%, OPI3=100%, AMP=100%, COC=100%, and

PCP=100%.

Reproducibility (THC, Opiates 300, Amphetamine, Cocaine, and PCP)

A panel of 55 naturally metabolized human urine samples was prepared. All samples in the panel had been screened for the presence

or absence of THC, OPI, AMP, COC, and PCP. In addition, each of the 55 samples had also been quantitated by GC/MS conducted at

SAMHSA cutoffs for positive samples or at limit of quantitation for negative samples to determine the concentration of a specific

drug. Five of the 55 samples were drug-free negatives and 50 of the samples were positive for one or more of the five drugs. The

concentration of primary metabolite in the positive samples was between 66 and 198 ng/mL for THC; 464 and 2000 ng/mL for OPI3;

1056 and 4622 ng/mL for AMP; 487 and 1342 ng/mL for COC; and 32 and 109 ng/mL for PCP. The panel was used to evaluate the

lot-to-lot and lab-to-lab reproducibility.

Lot-to-Lot Reproducibility (THC, Opiates 300, Amphetamine, Cocaine, and PCP)

Three aliquots of each of the 55 samples were prepared and each of the three sets of aliquots was coded and used to evaluate the

performance of one of three lots of drug tests for the five drugs above. There was one incorrect result (a false negative on an

amphetamine low positive sample) on the 825 tests for a reproducibility of >99%.

Lab-to-Lab Reproducibility (THC, Opiates 300, Amphetamine, Cocaine, and PCP)

Three aliquots of each of the 55 samples were prepared and each of the three sets of aliquots was tested by one of three study

participants using one lot of the five drug test panel above. There was >99% agreement between the three participants. Overall, there

were three incorrect results, two incorrect results for OPI3 (one false negative on an opiate low positive sample and one false negative

on an opiate high positive sample) and one incorrect result for PCP (one false negative a low positive sample), on the 825 tests.

Reproducibility (Opiates 2000)

A panel of 25 naturally metabolized human urine samples was prepared. All samples in the panel had been screened for the presence

or absence of opiates. In addition, each of the positive samples had also been quantitated by GC/MS conducted at SAMHSA cutoff

for positive samples to determine the concentration of morphine and codeine. The concentration of morphine and/or codeine in the

positive samples was between 2000 and 6000 ng/mL. The panel was used to evaluate Opiates 2000 for lot-to-lot and lab-to-lab

reproducibility. There were no incorrect results on the 75 tests (25 samples x 3 lots) for a lot-to-lot reproducibility of 100%. There

were no incorrect results on the 75 tests (25 samples x 3 study participants) for a lab-to-lab reproducibility of 100%.

Accuracy (Propoxyphene)

One-hundred forty one (141) clinical samples were evaluated by the Roche Abuscreen OnLine Propoxyphene assay, using a 300

ng/mL cut off. Sixty (60) samples were found to be negative and eighty-one (81) samples were found to be positive by the Roche

method. Three aliquots of each sample were prepared, and assayed by three operators in a masked manner. There was no significant

difference in the results obtained by the three operators, therefore the results of all three operators are included in the table. Results of

this comparison are as follows:

OnLine Positive OnLine Negative

PROFILE-II/VERDICT-II 238 0

PPX (300 ng/mL cutoff) 5 180

* GC/MS results are 390, 441, 499, 536 and 679 ng/mL

In addition to the 141 clinical samples, eight additional clinical samples containing only norpropoxyphene were diluted with drug-free

urine in order to obtain an adequate number of samples that had concentrations of drug that were challenging to the cutoff. These eight

diluted samples, and the 141 clinical samples described above were analyzed by GC/MS for propoxyphene and norpropoxyphene. The

level of quantitation of the GC/MS was 30 ng/mL. Only ten of the samples contained propoxyphene, and each of these samples had

norpropoxyphene levels greater than 1,647 ng/mL. As in the study above, three aliquots of the 149 samples were prepared, coded, and

assayed by three operators in a masked manner. There was no significant difference in the results obtained by the three operators,

therefore the results of all three operators are included in the comparison table.

Reproducibility (MAMP-MDMA)

A panel of 18 spiked human urine samples, comprised of drug-free and drug standard samples, was prepared. The panel was examined

by 3 operators, once a day for 5 days. The concentration of methamphetamine and MDMA had been quantitated by GC/MS in each of

the 18 samples. There was 100% agreement between the three operators over the 5 day period at 0 ng/mL, 1500 ng/mL (cut-off +

50%) and 2000 ng/mL (cut-off + 100%) for methamphetamine. There was also 100% agreement between the three operators over the

5 day period for 0 ng/ml, 2000 ng/mL (cut-off +33%), 2500 ng/mL (cut-off + 67%) and 3000 ng/mL (cut-off + 100%) for MDMA.

Accuracy (Tricyclic Antidepressants, Barbiturates, Methadone and Benzodiazepines)

The accuracy was evaluated by assaying a coded panel of clinical urine samples containing varying concentrations of drugs and

comparing the results to validated methods. A validated HPLC assay measured tricyclic antidepressant levels. Validated GC/MS

assays measured barbiturates, methadone and benzodiazepines levels. Results are shown in the following tables.

Accuracy in a Point of Care setting (Oxycodone)

The accuracy was evaluated by assaying a panel of blind coded clinical urine samples containing varying concentrations of drugs and

comparing to GC/MS results. The samples were obtained from MEDTOX Laboratories. Samples that screened negative by the

predicate device were not confirmed by GC/MS. Positive samples were confirmed by GC/MS. The GC/MS determination included

Oxycodone and oxymorphone and a weighted concentration using 100% cross-reactivity for Oxycodone and a 50% cross-reactivity

for oxymorphone was calculated. Clinical urine samples containing Oxycodone and oxymorphone at higher concentrations were

diluted with negative urine to obtain the desired number of samples with concentrations below and above the cutoff. The testing was

performed by nine point of care personnel at three sites.

A second, in-house accuracy study was done using many of the same samples as in the POC study above. Results between the two

studies were similar.

Sensitivity/Precision at One Location (Oxycodone)

Performance around the specific cutoff for Oxycodone was evaluated by testing standard drug solutions diluted in drug-free urine in

triplicate on 6 different intervals by 3 in-house operators. Drug free urine was also tested on each interval. The results were

interpreted at five minutes and are summarized below:

Interference-Oxycodone

pH and Specific Gravity:

The MEDTOX® OXYCODONE test was assayed with six negative clinical samples with pH values of 4.0, 5.0, 6.0, 7.0, 8.0 and 9.0 ±

0.1. Each sample was assayed in triplicate. The pH samples were fortified with Oxycodone to the concentrations of 25 ng/mL and 150

ng/mL. All the pH levels gave negative results when fortified to 25 ng/mL, and all pH levels gave positive results when fortified to

150 ng/mL.

The MEDTOX® OXYCODONE test was assayed with eight samples with specific gravity values of 1.003, 1.005, 1.010, 1.015, 1.020,

1.025, 1.030 and 1.035 ± 0.001. Each sample was assayed in triplicate. The specific gravity samples were fortified with Oxycodone to

the concentrations of 25 ng/mL and 150 ng/mL. All the specific gravity levels gave negative results when fortified to 25 ng/mL, and

all specific gravity levels gave positive results when fortified to 150 ng/mL.

Common Drugs:

Following the study of M.L. Smith, et. al.5 drug free urine samples were spiked with Oxycodone to the concentrations of 25 ng/mL

and 150 ng/mL. 100 µg/mL of the common drugs were then added to the preparation and assayed by the MEDTOX® OXYCODONE

test. Samples were evaluated in triplicate by in-house operators. None of the common drugs listed in the following table affected the

expected results.
