HBA1c

Hello Everyone,
First of all, I would like to say thank you to everyone in this forum, I was diagnosed last July with Prediabetes/borderline diabetes with an HBA1c score of 50 - and immediately found this forum, thank goodness I did.
I lost 3.5 stone (still some way to go, as a Size 16) but regular exercise and went LCHF and have managed to stick to that for the last year (with a little weekend treat, every couple of months). Lost 3 stone in the first 6 months, not too much more since then, only a half stone in the last few months, but slow and steady wins the race, and I feel much better.
Doctor prescribed Metformin, I take 1000mg per day, in the evening, and have been very strict since, do regular blood tests etc.
I recently went for another HBA1c (long story short, due to having a very high initial reading, doctor was happy to see me try and turn it around by losing weight and exercise, metformin to help, gave me a few extra months before making me do the blood test).
I just got my results - and its now 25, apart from being a huge drop, so am pleased, has me worried as its such a massive drop, is this something to worry about?
I don't think I have read much about scores in the 20's, please tell me all is fine!
Thanks again,
Georgina

Hello Dawnmc, thank you for replying!
I asked the receptionist at the doctors surgery 3 times, she said 25 at least 3 times, I kept asking her if she was sure! I am popping by after work to see for myself, just in case.
It does seem very low, am now concerned about that, I was hoping for 40 -42, if I am being honest, to be at the bottom end of prediabetes, high end of normal would have been nice enough.
I always thought the 50 could have been down to a very bad time I was having with my teeth (abcesses etc) and had a couple of months of popping ibuprofen like smarties, but the doctor says theres no such thing as a false positive HBA1c.
Oh dear, we are never happy, too high, too low!
Thanks

I did cry! If someone can tell me that 25 is OK, then I will feel a lot better!

Thank you all, I feel much better now, although may have to have a conversation with the doctor about Metformin!
Thanks
