Retest your blood glucose. If your blood glucose level is still 60 mg/dL or below, call your doctor immediately. Blood glucose results greater than 600 mg/dL are displayed as hi and your meter will beep in a high tone (if the Beep option is set to ). (Example) This message indicates very high blood sugar (severe hyperglycemia). You should call your doctor immediately. 38 Test results below 60 mg/dL3 (3.3 mmol/L) mean low blood Checking the Amount of Blood on the Test Strip glucose (hypoglycemia). Test Although the OneTouch® Basic® Meter results greater than 240 mg/dL4 requires only a small drop of blood, it is (13.3 mmol/L) mean high blood very important that the drop be large glucose (hyperglycemia). If you get enough to cover the test spot results below 60 mg/dL or above completely. 240 mg/dL, and do not have symptoms, first repeat the test. If In many cases, the meter can detect if you have symptoms and continue the drop of blood was too small to give to get results that fall below an accurate reading. However, it is 60 mg/dL or above 240 mg/dL, important that you also look at the test follow the treatment advice of your strip to make sure that you applied healthcare professional. enough blood. 39 ¦ If the following message Remove the test strip from the meter and look Front Side (Correct) at the test spot. It should still have a wet, shiny drop that completely covers the test appears on the display, your drop of spot. If the blood blood was too small, or smeared, or the sample has a dull, dry appearance, test strip was not pushed all the way you may not have applied enough into the test strip holder. Repeat the blood, or you may have smeared it. test with a new test strip and enough blood to cover the entire test spot. 40 ¦ Look at the back of the test strip. You should see a full, dark circle. If there are any white patches or streaks, you may have smeared the blood or the drop was too small. In either case, you may have a false low result. Repeat the test with a new test strip. Back (Correct) (Incorrect) 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: ¦ Make sure your meter is clean. ¦ Perform check strip and control solution tests to make sure the meter is working properly. ¦ 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. ¦ Take your meter with you to the lab. While at the lab: ¦ Make sure that both tests are done within 15 minutes of each other. ¦ Wash your hands before obtaining a blood sample. ¦ Never use your meter with blood that has been placed in a gray-top test tube. 42 Comparing the results: Example: ¦ When the lab tests your blood, only the serum or plasma portion is used. Your OneTouch® Basic® Meter uses only whole blood. ¦ 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. ¦ 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). ¦ Compare this figure to your meter 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 43 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. 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. 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. M C M C The word memory with the memory symbol will appear briefly. 45 If you are using the meter for the very most recent to the old...
