I want to add something about the iron panel. Together, these tests can give a pretty good idea of one's iron status, but no blood test or group of tests will be 100% definitive. A biopsy may be the only way iron could accurately be measured but this also has its limitations and seems to be overkill for determining iron deficiency. A two week test of taking iron should quickly tell one if their symptoms can be improved with iron supplements. Low ferritin does not necessarily mean iron deficiency even though most doctors will treat it as such. I tend to feel that iron deficiency is far less common than believed and for good reason. Our bodies have no natural way to remove iron. We lose about 1 mg iron daily from loss of skin, hair and blood, but 1 mg is far less than what we take in daily through diet, so it seems that it would be very difficult to actually be iron deficient without significant blood loss. On the other hand, there is tremendous evidence that people have too much iron in their bodies, as bacteria, viruses and cancer all thrive in a high iron environment, which has to make one wonder why iron is pushed so much.
Thalfriend, if you took iron and you felt worse while taking it, there is a very good chance you don't need it. Have you had the iron studies done yet?
