Des, I don't really know the answer to this one, but you should definitely be able to go to your GP and tell them you would like them to check your blood iron levels. It is a simple, cheap blood test and there's no reason they shouldn't do it, especially if you're feeling symptoms of iron deficiency. Also, a lot of other deficiencies can mimic iron deficiency. Are you able to eat any sort of veggies, V8, etc.?
