What Does It Mean When Glucose Is High In A Blood Test?

Glucose Screening And Glucose Tolerance Tests

Why do I need a glucose screening test during pregnancy? Most healthcare practitioners routinely recommend a glucose screening test (also called a glucose challenge test or GCT) between 24 and 28 weeks of pregnancy to check for gestational diabetes. Gestational diabetes is a high blood sugar condition that some women get during pregnancy. Between 2 and 5 percent of expectant mothers develop this condition, making it one of the most common health problems during pregnancy. And because the condition rarely causes any symptoms, testing is the only way to find out whether you have it. Like any screening test, the GCT won't give you a diagnosis. Instead, it's designed to identify as many women as possible who may have a problem and need more testing to find out. So a positive result doesn't mean that you have gestational diabetes. In fact, only about a third of women who test positive on the glucose screen actually have the condition. If you test positive on the screening, you'll need to take the glucose tolerance test (GTT) – a longer, more definitive test that tells you for sure whether you have gestational diabetes. Your practitioner may want you to be screened earlier than 24 week Continue reading >>

    Which is the best Glucometer? How accurate is Bayer's Contour Next? How do the glucometer readings compare with the laboratory blood test results?
    I appreciate any advise.

    The best for me is the one that the insurance company will pay for the test strips. Had been using the One Touch Ultra Mini and switched this year to the Bayer Contour Next. It does not matter as long as you are consistent to look for trends.

    All meters have to be within 20% of the acual BG number, and I believe most are more accurate than that, esp when BG is in or close to non-diabetic ranges.
    If you want to compare it (any meter) to lab tests, take the meter with you next time you go to have blood drawn and test with your meter immediately before or after your blood is drawn. Make a note of the number and a reminder to check that number against lab results; then when you get the lab results, you can compare the two numbers and see how close they are. When I've done this, I've always been satisfied 'cause the numbers were very close (sometimes identical).
    I don't know that there's any one that's "the best" but, like Nita said, the one that insurance will cover (esp for your test strips, which is where the real expense comes in) is probably the best option.
    There are some differences, mainly re: things like size and bells and whistles (like, can you download info from the meter to your computer, what kind of notification/sound do you get when the test is done, does the meter talk), but otherwise, I don't think there are huge differences between them--the main difference, it seems, is in how the display looks (at least, that's true of the meters I've used).

    "Just" really means "plus" keeping stress in check, getting enough sleep, changing my work schedule as needed, timing my meals and snacks, making time to take care of non-work and non-diabetes needs (as well as diabetes and work needs), and making time for just me, myself, and I. :-)
