How do doctors test for type 2 diabetes?

I have a doctor’s appointment tomorrow and due to my weight of 315 pounds and the fact that I would be considered morbidly obese with a BMI greater than 40, I will most likely be tested for type 2 diabetes. I wouldn’t be suprised if I do have it though.

    The first test to do is called A1C. this is a simple blood test that most doctors do in their office in 5-10 minutes IF they have the equipment. if not, they will take a blood sample and send it to a lab for 2-3 days.

    A1C Test measures the AVERAGE of your blood sugar over the last 90 days. NORMAL is between 5 and 6.

    if the A1C is more than 7, the doctor may want a second test called Glucose Tolerance Test (GTT). This is a more complicated test. it takes longer (3-4 hours) and is a bit painful.

    But GTT will give a definitive YES or NO answer, if the GTT says YES then you are diabetic and you need to start treatment immediately.

    Some doctors use the Finger Stick Blood Glucose Test. They stick your finger, then take ONE DROP of blood into a handheld meter. The readings come back in 30 seconds. This is the same test diabetics do 3-4 times a daty to control their blood sugar.

    The problem with this test is that it is affected by WHEN, WHAT, and HOW MUCH you’ve eaten. Therefore, for purposes of DIAGNOSIS it is unreliable.

    Since the A1C was invented (3-4 years ago) the “Finger Stick” test should NOT be used for diagnosis. The Finger Stick test is for CONTROL only.

    Given you weight, you should INSIST on getting an A1C test. If the doctor pricks your finger and puts blood into a HANDHELD METER, this is NOT an A1C test (it is the figner stick test). Insits that the doctor do the A1C test properly.

    As well, you should insist that the doctor repeat the A1C test every 3-4 months. You might not have diabetes now, but you could start next week. The A1C test will catch diabetes early enough that you can begin treatment and avoid the damages diabetes causes — blindness, kidney disease, amputations, sexual dysfunctions.

    And of course you know the drill — watch your diet, get more exercise, lose weight. Sounds like a broken record, but this is how you control diabetes. if you don’t already have it, this is how you keep it away.
