More on the test...
Coombs test (also known as Coombs' test, antiglobulin test or AGT) refers to two clinical blood tests used in immunohematology and immunology. The two Coombs tests are the direct Coombs test (also known as direct antiglobulin test or DAT), and the indirect Coombs test (also known as indirect antiglobulin test or IAT).
COOMB'S Test (Indirect)
The indirect test looks for anti-RBC antibodies that flow freely in blood serum, which is the clear yellowish fluid left after red blood cells and clotting materials are removed. The indirect Coombs' test is only rarely used to diagnose a medical condition. More frequently, it is used to determine whether a person might have a reaction to a blood transfusion.
