Tests for diabetes don’t always agree
I am confused about tests for diabetes. I had some blood sugar measurements near 300. That means I have diabetes. However, my HbA1C blood test was always below 6, which I understand is considered normal. No doctor has been able to explain this discrepancy.
Then my physician ordered that nasty lengthy test where you have to have your blood sugar measured three times in two hours after you drink some sugary stuff. This test confirmed that my body can’t handle sugar well. The levels were out of whack.
I started taking medication for diabetes and was able to get my blood sugar levels down. Why didn’t the A1C test EVER indicate any issue?
A new study suggests that the oral glucose tolerance test (OGTT) you describe is far more accurate than the AIC blood test doctors often use. The researchers conducted both tests for 9,000 people who had not been diagnosed with diabetes (Annual Meeting of the Endocrine Society, March 2019). The OGTT revealed diabetes in many people whose levels of hemoglobin A1C were within the normal range.

I have taken generic levothyroxine for many years after my thyroid was removed. Recently, my pharmacy chain changed the manufacturer. I was taking Mylan and was told it was no longer available in my strength (125 mcg). I was switched to Lannett. Then after only two months, I was switched again to Sandoz.
So I have taken levothyroxine by three different manufacturers in less than six months. I’ve heard it is not good to change manufacturers. Can you tell me if this is a problem? If so, what can I do about it?
It doesn’t sound as if you have experienced symptoms of under- or overdosing from these switches. That is the main concern: While generic manufacturers can maintain consistency within their lines of levothyroxine, the dose isn’t always comparable between generic drug makers.
If you’ve not experienced problems, you don’t need to do anything. If you have, however, you may need to find a pharmacy willing to supply you with levothyroxine from the same generic manufacturer for a reasonable time.
