About this test

The Coombs test looks for antibodies that bind to red blood cells and cause premature red blood cell destruction or haemolysis.

There are two types of Coombs tests, direct and indirect.

Direct Coombs tests are used to detect antibodies that are already bound to the surface of red blood cells. Many diseases and drugs such as methyldopa, quinidine and procainamide can lead to the production of these antibodies, which sometimes destroy red blood cells and cause anaemia.

A Direct Coombs test can also be used to diagnose the cause of anaemia or jaundice.

Indirect Coombs tests look for unbound circulating antibodies against a series of standardised red blood cells. The indirect Coombs' test is only rarely used to diagnose a medical condition, but is used to determine if a person may have a reaction to a blood transfusion.
