Coombs Test (Indirect)

The Indirect Antiglobulin Test (IAT) is another name for the Indirect Coombs Test (ICT) (IAT). It is used to determine whether or not there are antibodies in the blood directed against antigens located on red blood cells.

The ICT test is used to establish compatibility with donated blood before giving blood, tissue, or organs, before receiving blood during a transfusion to determine compatibility with donated blood, and during pregnancy to assess the risk of incompatibility between mother and fetus.

The indirect Coombs test is based on the antigen-antibody response premise. It is used to detect low antibody concentrations in a patient's plasma. Compatibility testing, antibody detection, RBC phenotyping, and titration investigations are possible with the IAT.
