Hemolytic Anemia by Areej T.Kadhum

Hemolytic Anemia by Areej T.Kadhum. Haemolysis. Normal life span of a RBC is 120 days (80-90 days in a full term infant). Senescent RBC is detected & cleared by RE. Reduced/shortened life span = premature cell destruction + No marrow compensation ? Abnormal hemolysis

Hemolytic Anemias

Hemolytic Anemias. Defined as those anemias result from an increased in the rate of red cell destruction. The red cell destruction is usually removed extravascular by macrophages of reticuloendothelial system (RE) [BM, liver & spleen]. Acute destruction or chronic destruction
