The direct Coombs' test may be used if doctors suspect a person is affected by a type of anaemia called haemolytic anaemia. Haemolytic anaemia is a condition where there are not enough red blood cells in the body because something in the body is destroying them.
The indirect Coombs test is used in prenatal testing of pregnant women and in testing blood prior to a blood transfusion. It detects antibodies against RBCs that are present unbound in the patient's serum. In this case, serum is extracted from the blood sample taken from the patient.
