| Question | Answer |
|---|---|
| laboratory findings when Storage Iron is depleted | decresed ferritin, increased TIBC |
| laboratory findings when serum iron is depleted | decreased serum iron, decreased % saturation |
| Why is it necessary to sequester iron during chronic inflammation | to prevent bacteria from accessing iron which is necessary for their survival |
| Lab findings in anemia of chronic desease (ferritin, TIBC, serum iron, % saturation) | increased ferritin, decreased TIBC, decreased serum iron, decreased % saturation, increased FEP |
| rate limiting step in protoporphyrin synthesis | Aminolevulinic acid synthetase (ALAS) converts succinyl CoA to aminolevulinic acid (ALA) |
| Laboratory findings of sideroblastic anemia | increased ferritin, decreased TIBC, increased serium iron and increased % saturation (iron overload state) |
