Heme-Specific Antibodies

A healthy adult human has about 2-3×1013 red blood cells (RBC) with a hemoglobin (Hb) content of about 3.108 molecules/RBC, equivalent to ~109 heme molecules per RBC. Clinically silent intravascular hemolysis can lead to the release of relatively high levels of biologically active Hb into plasma. The prosthetic heme group of extracellular Hb can be
