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.
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.

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]

If positive, the antibody is identified and given a titer. Critical titers are associated with significant risk of fetal anemia and hydrops. [14]
Mothers who are negative for the Kell 1 antigen develop antibodies after being exposed to red blood cells that are positive for Kell 1.Over half of the cases of hemolytic disease of the newborn owing the anti-Kell antibodies are caused by multiple blood transfusions, with the remainder due to a previous pregnancy with a Kell 1 positive baby.
Neonatal jaundice is a yellowish discoloration of the white part of the eyes and skin in a newborn baby due to high bilirubin levels. [1] Other symptoms may include excess sleepiness or poor feeding. [1] Complications may include seizures, cerebral palsy, or kernicterus. [1] In most of cases there is no specific underlying physiologic disorder. [2]
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.
