Hello,
Off coronavirus topic.....
For the past 2 years my hba1c has been different to my libre estimated a1c by around 5 or 6. Which is quite a lot. Whilst pregnant it was out by 12 (estimated 48 but was 60 on test). When I asked my nurse about it, she told me that anemia will give a false hba1c and to go with the libre. She said the libre is a much better way of knowing what your sugars are doing and not an hba1c.
I have just had my hba1c come out at 66, while libre is estimating 50.
I have searched and searched for reliability of the tests and the libre. Libres are calibrated before they come out and considered very accurate. Hba1cs are considered accurate within 0.5%...... I'm so confused.
Finger picks show accuracy on my libre.
I'm wondering if the survival rate of my rbc has come into it. A few weeks ago I had a particularly stressful time and sugars were high for a good couple weeks. Until my fight or flight wore off, I couldn't get them down. But now they are back to being in range 75% of the time.
I had my hba1c test directly after this stressful episode, so I was expecting a higher reading, but not that high. So I'm wondering if the rbc that were tested were only a month old at most and that explains the higher hba1c than I was expecting.
Which leads to my next question. What would cause my rbc to not live a 3 month cycle?
Anyone got any super knowledge on this?!
Thanks x
