[. . . ] Directly after reading a meter result, you can compare the color of the test strip confirmation dot with the colors on the chart. The color of the confirmation dot will either match one of the colors on the chart or fall between two colors. When the color of the blue dot falls between two colors, your blood glucose 33 level is between the values printed next to the two colors. This comparison will give you a rough estimate of your blood glucose level. TESTING Note: If your Color Chart reading and meter result do not agree and do not reflect how you feel, follow the testing tips for accuracy on pages 38­39. Do not use the Color Chart with control solution tests. U N D E R S TA N D I N G Y O U R R E S U LT S Overview Recent Diabetes Findings. In 1993 the National Institutes of Health concluded an extensive longterm study of people with Type 1 diabetes. This study, called the Diabetes Control and Complications Trial (DCCT), found that by keeping your blood glucose close to the levels of people without diabetes you can reduce the risk of complications involving the eyes, kidneys, and nervous system by approximately 60%. 1 What This Means for You. Frequent blood glucose testing is the best means you have for keeping track of how well you are doing with the factors that affect your diabetes--medication, diet, exercise, and stress management. Blood glucose test results can also tell you whether your diabetes is changing in ways that might require an adjustment to your treatment plan. Always consult your healthcare professional before making any adjustments. RESULTS 34 Frequency of Testing. How often you need to test your blood glucose will vary according to your age, the type of diabetes you have, the medications you are taking, and your physical and emotional health. After you decide when and how often you should test, it is important that you make testing part of your daily routine. Comparing Meter and Laboratory Results The SURESTEP® System's plasma calibration enables you to more directly compare SURESTEP Meter results with your lab results because most laboratories measure plasma glucose; however, your meter blood glucose test result may be different from your laboratory result (by up to 20%)2 due to normal sources of variation. Make sure you are following Testing Tips to Ensure Accuracy on pages 38­39. To make an accurate comparison between meter and laboratory results, the meter test must be done within 10 to 15 minutes of the laboratory test. If samples are taken more than 15 minutes apart, the two tests could have very different results. Blood glucose levels can change significantly over short periods, especially if you have recently eaten, 35 RESULTS exercised, taken medication, or experienced stress. 3 In addition, if you have eaten recently, the blood glucose level from a fingerstick can be up to 70 mg/dL higher than that of a venous sample (blood drawn from a vein) used for a laboratory test. 4 Therefore it is best to fast for eight hours before doing the comparison tests. Factors such as a high or low hematocrit (amount of red blood cells in the blood) or severe dehydration (loss of body fluid) may also cause a meter result to be different from a laboratory result. For more detail, see pages 39­40. Expected Test Results (Target Range) Your test results will vary somewhat from test to test. The types and amounts of food you eat, your activity and stress levels, and how much insulin or other medication you take affect your blood glucose levels. If you are controlling your diabetes well, your test results should fall within a personal target range recommended by your healthcare professional. Once you have established your target range, you will be able to detect when your results are high or low and can take action with advice from your healthcare professional. 36 RESULTS GLUCOSE RANGES FOR PEOPLE WITHOUT DIABETES, 5 mg/dL YOUR TARGET RANGES, mg/dL Before breakfast Before lunch or dinner 1 hour after meals 2 hours after meals Between 2 and 4 a. m. 70­105 70­110 Less than 160 Less than 120 Greater than 70 ______________________ RESULTS ______________________ ______________________ ______________________ ______________________ 37 Testing Tips to Ensure Accuracy If you have a test result that falls outside of your target range and you cannot link it to diet, exercise, medication, or stress, repeat the test.
