Hi all. I have recently been for a blood test - to investigate possible diabetes or thyroid problems. I have just received a letter saying my doc wants the blood test repeated and it specifys no alcohol for 2 weeks preceeding the blood test. The receptionist said there wasn't a problem and that blood tests are often repeated for very simple reasons. I'm a bit puzzled by the no alcohol bit. Its not a problem at all to abstain, I only have the odd glass of wine. The last blood test was a fasting blood test. Any ideas?
