Had my hb1ac checked over a year ago and it was 37 - since then I have lost 2.5stone with the help of mounjaro. Thought l'd have it checked again but didn't want to waste a doc appointment on it so bought a test off Ebay- l really struggled to get the blood and couldn't fill it to the line but sent what little l could. Had the results back to say it is now 48 - how accurate are these tests? Should l be panicking?
