Yes, it's a good idea to get a hold of your lab results. Start keeping track of all your labs. Find out what your B12, iron, folate, zinc, copper and B6 levels are. You need to know the specific number, not just "normal" or "low". If any of those are low normal or below normal, I would work to correct that first since you are apprehensive about another bone marrow biopsy and your counts are not that low at this point.
Iron is difficult to take. Some types are easier than others. Pre-menopausal women are more likely to be iron deficient. Vitamin C, taken with meals, can help
increase the absorption of iron from your diet. And, anything with tannins in it, like tea, coffee, or wine will
decrease the absorption of iron.
If you are a vegetarian, you may not be getting enough B12 or iron in your diet.
They can also do your bone marrow biopsy under sedation so ask them about it when you go to schedule the procedure. John got his first with out. Not anymore
