The HbA1c blood test or glycosylated haemoglobin is used as a general indicator of average blood sugar levels present in plasma over about 3 months. It does not indicate whether a person is insulin resistant or not, whether they have high blood sugar or low blood sugar at times, only what the long term average blood sugar level is.

It makes no differentiation between someone who has a steady blood sugar level of 5-6 mmol/L and someone who cycles constantly between hypo and hyperglycaemia going to 15 mmol/L after a meal and then crashing down to 3 mmol/L or less soon afterwards, the latter being a typical expression of insulin resistance. It is frequently used to monitor diabetics in addition to regular blood glucose monitoring at home, or to diagnose diabetes.

There are many factors which can affect the results of an HbA1c test, such as any process affecting the red blood cell volume or turnover rate including blood loss, anaemia, surgery, blood transfusions, erythropoietin treatment as well as chronic kidney or liver disease and even high doses of vitamin C. Different assay techniques also provide different HbA1c results. It is possible for 2 people with the same average blood glucose level to have an HbA1c result which differs by as much as 3 percentage points, which can be quite significant!

I was diagnosed with IR after they checked my fasting insulin, my fasting glucose, and my c-peptide simultaneously. I then also had a glucose tolerance test to help confirm it.

Not every woman who has PCOS has insulin resistance, but it its very common. Your A1C and glucose levels can be normal even if you have insulin resistance. There its a simple blood test to check insulin levels that can indicate that you have insulin resistance. It is not the same as an glucose or A1C screening. It may be possible that you don't need the Metformin but an insulin level check (preferably taken fasting) should be done first.

Hi everyone
My name is Maggy and i am 33 , mom of 2. Rx in 2005 ): I moved from Kansas to Texas last year and that made me change my doctors. My new Gyn. tested my A1C and says its normal. He says that i dont need the Metformin (1500 mg) that i tool before because i dont need it. My question is, if i still have PCOS then doesnt insulin resistance come with it ? If so , is there any other test for insulin resistance ? Isnt the met for pcos ?

Sorry i am so confused ....and worried that stopping the metformin will make worst .

Please reply .
