Default Test Results

After 12 months reducing my carbs in varying degrees (and quite a few major blow outs along the way) my fasting insulin has dropped from 32 down to 7 (range less than 20). I have also lost around 9kg. However my HbAlc remains unchanged at 5.8% ... had 4 tests over the last couple of years and every one, 5.8%. I am GAD positive, latest c-peptide is .75 (range is .4 to 1.5).

Should my HbAlc have dropped along with the insulin? (maybe it would have if I hadn't had so many blow outs!)

Your HbA1c reflects (roughly) your average blood sugar over the lifetime of your red blood cells -(typically taken as three months).

5.8% maps to around 6.7 mmol/L. The point here is that it is an average. So, it might reflect a rack of figures lying between 6.4 and 7.0 - or it might reflect a mix of figures between 3.5 and 10.

Without test figures giving a picture of your pattern, it's impossible to say.

Being GAD positive, indicates type 1. Your insulin dropping indicates possibly you have been eating less carbs prior to testing, but more likely, your pancreas is producing less insulin. It may be that you honeymoon phase of type 1 is ending and you will be needing insulin full time. Just my opinion.

Think I've had this since 2003. Told I was Type 2 lean on 2/13/12.

What is your daily blood-sugar management regimen. We can give you more specific help if we know the specifics of your diet, testing times and levels, and insulin doses.

The HbA1C test does measure the glycated red blood cells over the last four months or 120 days. The last 30 days accounts for 50% of the A1C value. The prior 31 to 59 days accounts for 25% of the A1C value and the prior 60 to 120 days accounts for the final 25% of the value. This was taught me by David Mendosa in his blog here - How Often to Check A1C - A1C and blood sugars - Diabetes

It sure is a weighted average. I take it as 50%, 25%, 15% & 10% over the past 4 months. Just MHO.

A1c & serum insulin would not be related especially with the presence of antibodies. Honeymooning or not 5.8 is a good number, and you've maintained it. Well done.

A1c ~ 5.4
