Hello,
I need some advice.
Back in 2022, I had a blood test at my GP's and the HbA1c was 41 (5.8%)
My GP said I was close to pre-diabetes level so he asked me to adjust my diet a bit.
What I notice is that my blood in the morning is always between 5.4 and 6.2%, depending how late and how much I eat in the evening. It might be the way my body works.
Despite this, I managed to lower HbA1c to 5.5% over six months. I kept measuring it every 6 months from 2023. It remained between 5.4 and 5.5% until March 2024, where it went down to 5.23%.
However, I had a blood test on the 23rd of August and HbA1c was 5.98%.
I was a bit surprised by the sudden increase of the HbA1c result. However, I then decided to retake the test in a different lab, technically with better standards roughly 2/3 weeks later, and the result was 5.6%, which is within the acceptable limits.
I followed a better diet between the two tests. I was a bit surprised that I could fix the test result fairly quickly. Do you think it's just the lab or a better diet can have such an impact in a fairly short time?
 
theres a greater emphassis on the directly preceeding few weeks for hba1c. labs have margin for error as well. with vein access more accurate than hba1c from fingerprick. how the labs tested will have an impact, duration between tests. for direct comparison between labs imo better taken at exactly the same time with one vial of blood sent to each lab.

from the above article said:
Across the assay range, POC test results from fingerstick and venous whole blood samples were highly correlated with results from the NGSP SRL (r = .99). The mean bias was −0.021% HbA1c (−0.346% relative) using fingerstick samples and −0.005% HbA1c (−0.093% relative) using venous samples. Imprecision ranged from 0.62% to 1.93% CV for fingerstick samples and 1.11% to 1.69% CV for venous samples.

Conclusions:
The results indicate that the POC test evaluated here is accurate and precise using both fingerstick and venous whole blood.

could be a combination of factors.
