Shipping InformationShip in insulated container with freezer packs.
Collection ProtocolCollect blood into a red-top vacutainer; avoid hemolysis. Separate serum from cells as soon as possible following collection and transfer to a leakproof tube. Refrigerate until shipped.
Nearly all iron in non-hemolyzed serum is bound to transferrin, therefore serum iron concentration represents the amount of transferrin-bound iron.
