Iron is an essential trace element that is mainly derived from dietary sources. Iron is needed to assist in the formation of adequate numbers of normal red blood cells, which carry oxygen throughout the body. Iron is a critical part of hemoglobin, the protein in red blood cells that binds oxygen in the lungs and releases it as blood travels to other parts of the body.

he Iron Studies assessment will detect and evaluate abnormalities of iron metabolism by measuring Iron, Ferritin, Transferrin, and Transferrin Saturation. The assessment will provide information on the potential need for oral iron replacement therapy, or haematology referral.
