[QUOTE="Bluetit1802, post: 1420550, member: 94045"] If you are anaemic (or have been) your HbA1c may not be a true representation depending on the type of anaemia you have. This is because the HbA1c relies on you having normal standard haemoglobin, which certain anaemics don't have. Many other people also don't have standard haemoglobin because their red blood cells don't live for the standard 8 to 12 weeks that the HbA1c relies on. . Not everyone falls within standard, in fact, many don't. If our red blood cells live longer than 8 to 12 weeks or less than 8 to 12 weeks our HbA1cs won't be accurate. The correct test for anaemics is the Fructosamine test. Many (most) GPs are reluctant to order this because it is more expensive and very few labs actually do them, so the sample has to be sent away. It is similar to the HbA1c in that it works on a rough average, but instead of over 2 to 3 months it is over 2 to 3 weeks. Then there is the OGT which is a test of your post meal reaction. You drink some glucose - usually Lucozade, and are tested before, at an hour and again at 2 hours. It may be worth your while discussing these 2 tests with your GP.

For example, people with forms of anaemia may not have sufficient haemoglobin for the test to be accurate and may need to have a fructosamine test instead. [/QUOTE]
