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.
How is it used? The direct antiglobulin test (DAT), also known as the direct Coombs test, is used primarily to help determine whether the cause of hemolytic anemia, a condition in which red blood cells (RBCs) are destroyed more quickly than they can be replaced, is due to antibodies attached to RBCs.
