6 Factors That Can Affect Blood Sugar Readings

When testing your blood sugar, there are a host of issues that can affect the accuracy of the results. This is not only frustrating but also dangerous—you want to make sure you’re giving yourself the right amount of insulin to regulate your blood sugar if you’re taking insulin, and you want to make sure you know your real numbers to work with your doctor to control your blood sugar and avoid complications. Avoid these six common problems before you prick that finger: User technique You may not be getting a big enough sample of blood on the test strip to precisely measure your blood sugar. You also may be using the same finger for every test. And there are other commonly performed missteps in testing. User error is a large contributor to inaccurate readings, so talk to your endocrinologist or CDE about how to properly perform all the steps involved in testing. Dirty testing site Are your fingers a little sticky from just-eaten food? If you ate an orange and left residue on your fingers, your meter will add the high sugar content from the citrus to your blood sugar measurement, resulting in a much higher number than you actually have.

    Something bizarre!
    I seem to be getting significantly different blood sugar results when I take blood from a finger on my right hand from when I take it from a finger on my left hand.
    The results on my left hand are always lower. Just a coincidence, or could this be that the blood from my left arm/hand is more oxygenated, as it is closer to my heart. It could also be that the BS meter is unreliable. It was one of the cheapest available on Amazon.
    Can anyone recommend a really good BS meter?
    I also find it easier to take blood from the fingers on my left hand, as the blood erupts more easily and generously when I puncture a finger on my left hand, rather than my right.

    Hi Maverick,
    You know what, I'm curious to see this one answered too as I have only ever tested from my left hand, and I'm a newbie.
    As for meters I like many here use the code free as it's a pretty reliable unit with super cheap test strips.
    Here's a link for the meter, there are also discount codes which make it even cheaper, not sure what they currently are but I'm sure someone will pass by and drop the voucher codes off for you.
