Coombs reagent (also known as Coombs antiglobulin or antihuman globulin) is used in both the direct Coombs test and the indirect Coombs test. Coombs reagent is antihuman globulin . It is made by injecting human globulin into animals, which produce polyclonal antibodies specific for human immunoglobulins and human complement system factors.
Blood testing for the mother is called an indirect Coombs test (ICT) or an indirect agglutination test (IAT). This test tells whether there are antibodies in the maternal plasma. If positive, the antibody is identified and given a titer. Critical titers are associated with significant risk of fetal anemia and hydrops. [1]
Newborn infant with Rhesus disease, a type of hemolytic disease of the newborn, suffering from hydrops fetalis (edema caused by heart failure). The infant did not survive. [4] Signs of hemolytic disease of the newborn include a positive direct Coombs test (also called direct agglutination test), elevated cord bilirubin levels, and hemolytic anemia.
Hemolytic disease of the newborn (anti-Kell 1) is caused by a mismatch between the Kell antigens of the mother and fetus. About 91% of the population are Kell 1 negative and about 9% are Kell 1 positive. A fraction of a percentage are homozygous for Kell 1. Therefore, about 4.5% of babies born to a Kell 1 negative mother are Kell 1 positive ...
Coombs - after birth, the newborn will have a direct Coombs test run to confirm antibodies attached to the infant's red blood cells. This test is run from cord blood. [5] In some cases, the direct Coombs will be negative but severe, even fatal HDN can occur. [15] An indirect Coombs needs to be run in cases of anti-C, [16] anti-c, [16] or anti-M ...
In some cases, the direct coombs will be negative but severe, even fatal HDN can occur. [12] An indirect coombs needs to be run in cases of anti-C, [13] anti-c, [13] and anti-M. Anti-M also recommends antigen testing to rule out the presence of HDN. [26] Hgb - the infant's hemoglobin should be tested from cord blood. [1]

Blood compatibility testing is routinely performed before a blood transfusion.The full compatibility testing process involves ABO and RhD (Rh factor) typing; screening for antibodies against other blood group systems; and crossmatching, which involves testing the recipient's blood plasma against the donor's red blood cells as a final check for incompatibility.
