I still do not have an intended use statement. It should not be used for the diagnosis of diabetes? The TheraSense Continuous Glucose Monitor helps people with diabetes monitor their sugar (glucose) level. The system provides glucose values on a continual basis allowing you to see patterns in your glucose levels. The Continuous Glucose Monitor System includes: • a sensor, which is inserted under your skin and takes glucose measurements for up to 72 hours • a wireless transmitter that connects to the sensor and sends glucose results to a receiver • a wireless receiver that captures and displays the glucose measurements sent by the transmitter Glucose levels are measured and displayed every 3 minutes from a tiny sensor inserted just below the surface of your skin. The top of the sensor sits above the skin and connects to a transmitter, which sends glucose readings to a receiver that you keep with you like a pager. The receiver displays the glucose values, and also functions as a FreeStyle blood glucose meter, allowing you to perform discrete blood glucose tests using a FreeStyle Test Strip. By getting more frequent glucose results over time, you can monitor your glucose levels more closely and gain more control of your diabetes. Understanding the continuous trend of glucose levels, rather than several isolated readings will help you and your healthcare professional to adjust your treatment plan and understand how your diet, insulin, exercise, and medication are affecting your diabetes. Therasense Confidential iii Safety and Precautions Important Information About Your Continuous Glucose Monitor Confidential • Therasense Before using the Continuous Glucose Monitor to test your glucose, read this owner’s booklet and practice the testing procedures. • Glucose monitoring should be done with the guidance of a healthcare professional. • • • • • Do not leave a sensor inserted under your skin for more than 3 days (72 hours). Do not fly on an airplane while you are wearing a transmitter. Do not swim in salt water. Do not drop the receiver or allow it to get wet. The receiver should be used only with the FreeStyle Test Strips and Control Solution. Using other brands of test strips or control solution with the receiver can give you inaccurate results. Important Health Related Information • • • • Severe dehydration and excessive water loss may cause false low results. If you believe you are suffering from severe dehydration, consult your physician immediately. Test results below 60 mg/dL (3.3 mmol/L) mean low blood glucose (hypoglycemia). Test results greater than 240 mg/dL (13.3 mmol/L) mean high blood glucose (hyperglycemia). If you get results below 60 mg/dL or above 240 mg/dL, and you do not have symptoms of hypoglycemia or hyperglycemia, repeat the test. If you have symptoms or continue to get results that fall below 60 mg/dL or above 240 mg/dL, follow the treatment advice of your healthcare professional. If you are experiencing symptoms that are not consistent with your blood glucose test results AND you have followed all instructions described in the Continuous Glucose Monitor Owner’s Booklet, call your healthcare professional. Help is Available Help is available from your clinical trial site coordinator 24 hours a day, 7 days a week. Your site coordinator will provide you with contact information. You may also visit our website at www.therasense.com.
