There's a question in UWorld where a lead poisoning patient has normal serum iron studies. In the explanation it says "(In lead poisoning) Iron studies are normal unless co-existing iron deficiency is present as well".
Does anyone have any idea why that is? I was under the impression that - like all sideroblastic anemias - a lead poisoning patient would have increased serum iron, increased ferritin and normal to low TIBC. Goljan also lists iron studies in lead poisoning as having a sideroblastic pattern.
Any idea why UWorld says they're normal?
