[. . . ] Basic Owner's Booklet Blood Glucose Monitoring System Simple Easy To Handle Proven Accuracy The OneTouch® Basic® Blood Glucose Monitoring System is intended for in vitro diagnostic use for quantitative determination of glucose in whole blood as an aid in monitoring effectiveness of diabetes management in the home and in clinical settings. It is not intended for use in the diagnosis of diabetes or for neonatal testing (newborns 0­4 weeks old). CAUTION: Before using any product to test your blood glucose (sugar), read all instructions and practice the test. Do all quality control checks as directed and consult with a diabetes healthcare professional. These recommendations apply to all blood glucose monitoring systems and are supported by the American Association of Diabetes Educators, the American Diabetes Association, the U. S. [. . . ] Repeat the test with a new test strip and enough blood to cover the entire test spot. Remove the test Side Front strip from the meter and look at the test spot. It should still have a wet, shiny drop that completely covers the test (Correct) spot. If the blood sample has a dull, dry appearance, you may not have applied enough blood, or you may have smeared it. 40 Look at the back of the test strip. If there are any white patches or streaks, you may have smeared the blood or the drop was too small. Repeat the test with a new test strip. Back (Correct) (Incorrect) 41 COMPARING METER AND LABORATORY RESULTS The blood glucose test result you obtain from your meter may be different from your laboratory result due to normal variation; however, the two results should be within 20% of each other. 5 To make an accurate comparison between meter and laboratory results, follow these guidelines. Before you go to the lab: Comparisons will be more accurate if you have not eaten for at least four hours (and preferably eight hours) prior to doing the comparative tests. Never use your meter with blood that has been placed in a gray-top test tube. While at the lab: Make sure your meter is clean. Perform check strip and control solution tests to make sure the meter is working properly. 42 Comparing the results: Example: When the lab tests your blood, only the serum or plasma portion is used. Comparing serum or plasma to whole blood is like comparing a temperature of 98. 6°F with the temperature of 37°C--in order to see if the values are equal, you have to adjust one of the results. Whole blood results are approximately 12% lower than serum or plasma results. To compare lab results with meter results, divide the lab result by 1. 12. 43 Assume that your lab result (plasma or serum) is 224 mg/dL. 224 divided by 1. 12 = 200 (the lab value is now approximately equal to a whole blood result). The two should be within 20% of each other. You may still have a variation from the result because blood glucose levels can change significantly over short periods, especially if you have recently eaten, exercised, taken medication, or experienced stress. 6 In addition, if you have eaten recently, the blood glucose level from a fingerstick can be up to 70 mg/dL higher than blood drawn from a vein (venous sample) used for a lab test. 7 Therefore it is best to fast for four to eight hours before doing comparison tests. Factors such as the amount of red blood cells in the blood (a high or low hematocrit) or the loss of body fluid (severe dehydration) may also give a meter result different from a laboratory result. 44 USING THE METER MEMORY Your OneTouch® Basic® Meter automatically stores up to 75 test records. It stores blood glucose, check strip, and control solution test results with time and date. When you have stored more than 75 records, the oldest record is dropped from the memory as a new record is added. M C M C Entering the Memory Mode Turn the meter on by pressing the on/off button. You can access the meter's memory and recall test results at any time before or after performing a test by pressing the M button. 45 The word memory with the memory symbol will appear briefly. If you are using the meter for the very first time and have not used it for testing, or if you have used a software program to clear the meter's memory, the following message will appear, indicating that there are no results stored in the memory: most recent to the oldest, up to the full 75-record capacity of the memory. Test results will appear on the meter display as follows: (Examples) Recalling Test Results Pressing the M button allows you to see each blood glucose, check strip, and control solution test stored in memory. The records will appear in order from the When the memory returns to the most recent result, the meter will beep (if the Beep option is set to ). You can exit the memory mode at any time by pressing the on/off button. 46 SETTING METER OPTIONS You do not have to enter the set-up mode to test. However, you can customize the various option settings of your OneTouch® Basic® Meter to best meet your needs. Option settings (default settings shown) that you can customize include: Clock (Time and Date): Beep Prompts: Language: Time Format: Date Format: Unit of Measure: Decimal Separator: 47 To change the default settings, enter the set-up mode. Entering and Using the Set-Up Mode To enter the set-up mode, start with your meter turned off. [. . . ] Surwit, R. S. , and Feinglos, M. N. : Diabetes Forecast (1988), April, 49­ 51. Sacks, D.
