Ferritin is a protein that stores iron and releases it in a controlled fashion. Hence, the body has a "buffer" against iron deficiency (if the blood has too little iron, ferritin can release more) and, to a lesser extent, iron overload (if the blood and tissues of the body have too much iron, ferritin can help to store the excess iron).
I don't know. Sorry.
Iron levels in the body are measured by both hemoglobin and serum ferritin blood tests.
Have ferritin level of 587 & a fatty liver & cholesterol of 6.9
Ferritin is a protein that stores iron. Low ferritin is a precursor to anemia, so if you do nothing about the low ferritin level your iron level will eventually drop.
A ferreting blood test tests for the levels of ferreting in the blood. Ferreting is an iron storing protein, and high levels of this protein can be indicative of an iron storing disorder in the body.
