Blood Glucose Test: Tips For Accurate Results

    I observed that the size of the blood drop changes the meter reading. When I checked a tiny sized blood drop (just large enough to get a reading) and a sizeable blood drop (two to three times larger than the tiny one) gave me two different meter readings. Which of these is a better indicator of the true blood glucose level?

    What were the numbers? It may depend on your meter.
    The only difference I have ever noticed is an error message if the drop is too small. My present meter (Freestyle Lite) uses such a tiny drop that error is rare.

    I use a Bayer Contour USB.
    One time I didn't get a very big drop and the meter gave me a notice for more blood.
    When I stabbed myself again, the reading came back at 58.
    Stabbed yet one more time with a new strip and... viola... an 75 or so.
    I prefer to have a nice, big drop all the time, but sometimes my hands are cold and I forget to warm them up before the stab.
