glucose question

At wk 12, my glucose was little high, 106, fastening state
At wk 16, it was 101, however they made a mistake, and put it as NON fastening, even if I repeteadly told them that I did not eat anything that day.

So, my question is - how do they actually measure this in the fastening vs non fastening state?
Is it the same procedure and they just attached different ranges to it, or the measurement is different?

If the first case is true, it means that my 101 will be the same number in fastening, so I am still over the limit (99)
If they measure it different, than I compare apples with oranges...and I cannot tell if I improved a little or not.

Thank you

The difference between a fasting glucose of 101 and 106 is probably negligible. Both of your values suggest that you have impaired fasting glucose (range 100 - 125). The measurement is the same in fasting and non fasting testing - the difference is in the reference range. A normal fasting glucose is < 100 and the current thinking seems to be that even a result in the mid to high 90s might suggest close monitoring.
The answer to your question is that it doesn't matter whether they call it non fasting or fasting glucose test result. You know you were fasting and the numbers are what your blood glucose was on those two tests. And they are slightly elevates and fall within the range of impaired fasting glucose.
I think you should closely monitor your lab values and you might want to invest in a glucometer to test your blood yourself. The cost is often covered in whole or in part by the insurance company with a doctor's prescription. It would be nice if you had an idea of your post prandial (1 1/2 to 2 hours after meal) glucose number. And, you should also ask you doctor to give you a script for an HbA1c test for when you go for your next labs and reflects your blood glucose over a 3 to 4 month period. If you are taking ribavirin the HbA1c test may not be accurate and could very well give you an unrealistically low result due to the effects of hemolytic anemia. But, if you aren't currently treating and haven't treated for 3 or 4 months this test might be a good idea.

Thank you

I am treating, week 16 already, 6 pills Riba every day

I apologize for that. I realized it after I posted. So I wouldn't bother with an HbA1c test but I wouldn't rule out getting yourself a glucometer and test yourself. Good luck, Mike

Mirceani:

Mike has given good advice above; the A1c test results can be rendered inaccurate due to increased hemolysis from ribavirin.

Another test you might want to consider would be a glucose tolerance test; this is a simple test offered be almost any lab that involves establishing a baseline fasting glucose result, then having the patient ingest a known quantity of glucose in solution. Serum glucose samples are then collected at specified intervals to determine the rate of glucose metabolism. If you indeed have insulin resistance, this will be reflected in the time it takes your serum to return to baseline glucose levels.

Whatcha think, Mike?

That's a good idea. Mike

I've had a couple of minimally elevated blood sugars on my past couple of fasting labs, meaning the glucose.   My last one was 111.   My doctor told me that I just needed to have it rechecked in 3 mon. and keep an eye on it. My weight's not that bad and I exercise about 6-7 days a week.  My blood pressure and cholesterol are great.  Anyway, at the moment, I'm not on treatment.
