Hi Gert, thanks for your interest and help.

I've contated him today by email asking for valid tests as you suggested. Also I've done two personal blood tests (today and yesterday) just before breakfast. Results were 133 and 135.

Btw, I found some days ago a blood analitic from two months ago showing HbA1c at 5,40% (no prediabetes)

I'll update.


Regards.
