  • Do they tell you while you are at the doctor's office? Or does it take a few days?


  • takes a day or so, they have to send it out to the lab.
    hope that it comes back negative... i have diabetes and you do not want it. Good Luck!


  • They should be able to tell you immediately based on both a simple blood glucose test, which tells you your current blood glucose level, and a Hemoglobin A1C test, which tells the average level of your blood glucose over several months.


  • My son's endocrinologist can give you an HbA1c reading right there in the office. Fasting blood sugar can also be done in a minute. If diabetes is suspected the doc should be able to tell very quickly.

    When we knew something was wrong with my son, the doctor knew immediately what the problem was. A few tests in the hospital the next day to confirm the unfortunate diagnosis. He has type 1, perhaps diagnosing type 2 might take a little more time.


  • Capillary test with an instant stripe can throw results few seconds after.

    Veinous blood test done in a laboratory is more accurate, but results may be available next day.


  • It depends on the test and how it was done.

    if they took the blood into a test tube, it will take 2-3 days.

    But some doctor have the equipment to do the A1C test in their office in about 5 minutes, using one drop of blood. But that depends on the doctor, and how much he is willing to spend on lab equipment.

    [The one-time "Finger stick" test, the same test diabetics use on a daily basis, is not a good DIAGNOSIS tool. it is used to track your instantaneous sugar level, which could be high or low at any given time.]

    If they do a Glucose Tolerance test, that take 3-4 HOURS (and you have to drink that nasty sweet syrup stuff). In that case they can tel you almost immediately after the test is completed.
