Significance of test

The direct Coombs test (also known as the direct antiglobulin test or DAT) is used to detect if antibodies or complement system factors have bound to RBC surface antigens in vivo. A blood sample is taken and the RBCs are washed and then incubated with antihuman globulin. If this produces agglutination of RBCs, the direct Coombs test is positive, a visual indication that antibodies are bound to the surface of red blood cells.
This is the test that is done on the newborn’s blood sample, usually in the setting of a newborn with jaundice. The test is looking for “foreign” antibodies that are already adhered to the infant’s RBCs, a potential cause of hemolysis.
