WebCoombs test, also known as anti-globulin test, detects the antibodies that may agglutinate to the red blood cells and cause haemolysis (Ducrotoy et al., 2016). Normally, no direct agglutination takes place with red cells coated with IgG or complement and red cells are said to be sensitized with complement or IgG.

WebUse in a routine hospital blood bank laboratory for red cell phenotyping (ABO, Rh, Kell Mand N), direct antiglobulin test-ing (DAT), antibody screening and indirect antiglobulin test compatibility testing showed that care must be taken to ensure that no greater than a 1% suspension of red blood cells is used and that problems may be encountered ... WebABO discrepancies happen for a wide variety of reasons, including technical errors, problems with red cell antigens, or problems with serum antibodies.

Repeat testing with antisera from Immucor (Norcross, GA) resulted in true positive or true negative reactivity, resolving the mixed-field problem. Red Cell Phenotyping .
