FYI - For those of you with Haemochromatosis diagnosed or undiagnosed (very common) like a lot of people diabetes is basically a symptom of this condition. Worth getting an iron panel done as the 2 are like close siblings.
Also if you donate blood or do phlebotomy it will screw with any A1C test results and you will need to wait 3 months from blood donation to do an accurate A1C test again.
