Morning All,

I've just received the result of my fasting insulin test and @Bluetit1802 asked if I would post the result. So here goes, I had the blood drawn at 8am and my self test blood glucose at that time was 6. The result of the fasting insulin was 3.1. Not sure what this tells me but will add it to all other info for future reference. Also had a 4 point cortisol test which came out as optimal.

I am beginning to wonder if I my HbA1c results are accurate as my bg readings are generally in the 5s with a rise to high 6's and occasional 7's post prandial. My meter tells me I should have an HbA1C of about 34 but I've never achieved a number below 40. I believe for some people the longevity of their red blood cells could be more or less than 120 days and therefore an HbA1C could be flawed. I think @Bluetit1802 may have the same problem and has done some research into this.

This disease is like unravelling a messed up ball of string ....... frustrating!

Oh wow! That fasting insulin test is absolutely perfect!!!! It really could not be any better. :) Under 6 is optimal. The reference range for the general population is under 20, although anything over 8 is considered high. @CherryAA and @bulkbiker have all the figures and information on it. Hopefully they will come along with the information.

Yes, I believe I have flawed HbA1c results - always a lot higher than I believe they should be. There are several reasons why this can happen, longevity of the red blood cells (because we aren't all standard in this), also elevated haematocrit (PCV) levels can cause this. My Haematocrit levels are always (and always have been) at the very high end of normal. From my own averages and my Libre sensor readings I would expect an HbA1c of around 36, even being very cautious with my calculations, but I have never had less than 41.

Yes that fasting insulin is perfect at 3.1 - that coupled with great blood sugar figures suggests to me that whatever you are doing is totally optimal for your health and as such I wouldn't worry too much about the odd few points in Hba1C, all of the indicators simply suggest "keep calm and carry on"

Don't worry too much about the HbA1c it will come down and your next one should be lower than your last if you are getting such good BG readings. Great news on the fasting insulin as well. Looks like you are doing really well... keep it up!

Thanks very much for taking the time to post the above info @Bluetit1802 I'll have a read when I get a few minutes.
