WebMicroangiopathic hemolytic anemia(MAHA) is a microangiopathicsubgroup of hemolytic anemia(loss of red blood cells through destruction) caused by factors in the small blood vessels. It is identified by the finding of anemia and schistocyteson microscopyof the blood film. Signs and symptoms[edit] Spherocytes are found in immunologically-mediated hemolytic anemias and in hereditary spherocytosis, but the former would have a positive direct Coombs test and the latter would not. The misshapen but otherwise healthy red blood cells are mistaken by the spleen for old or damaged red blood cells and it thus constantly breaks them down, causing a cycle whereby the body destroys its own blood supply (auto-hemolysis). A complete blood count (CBC) may show …

The main function of RBCs, or erythrocytes, is to carry oxygen from the lungs to the body tissues and carbon dioxide as a waste product from the body tissues to the lungs back. … WebHaemolytic anaemia involves a fall in haemoglobin concentration caused by a shortened lifespan of circulating erythrocytes. Haemolysis can occur in the vasculature ( intravascular) or within the spleen ( extravascular ), although the latter is more common.
