If clumping is seen, the Coombs test is positive; if not, the Coombs test is negative. [ 3 ] Common clinical uses of the Coombs test include the preparation of blood for transfusion in cross-matching , atypical antibodies in the blood plasma of pregnant women as part of antenatal care , and detection of antibodies for the diagnosis of immune ...

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 ...
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 ...
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.

The full chapter can be found on pages 439 to 453 of Volume 1, which contains all (sub)categories of the ICD-9. Volume 2 is an alphabetical index of Volume 1.
Hemolytic disease of the newborn (anti-Rhc) can range from a mild to a severe disease. It is the third most common cause of severe HDN. Rh disease is the most common and hemolytic disease of the newborn (anti-Kell) is the second most common cause of severe HDN. It occurs more commonly in women who are Rh D negative.
