Test Code

Coomb’s Test (Indirect), also known as Indirect Antiglobulin Test (IAT), is used to detect circulating antibodies in a patient’s serum that may bind to red blood cells. Unlike the direct Coomb’s test, ICT does not test RBCs already coated with antibodies but checks for free antibodies that can cause hemolysis.
This test is widely used in blood transfusion compatibility testing, antenatal screening in pregnancy (especially Rh incompatibility), and in diagnosing immune-mediated hemolytic anemias. A positive ICT indicates the presence of clinically significant antibodies that may cause transfusion reactions or hemolytic disease of the newborn (HDN).
