red blood cell antibody screen

a test to detect antibodies against red blood cells for safe blood transfusion practices

A red blood cell antibody screen is a test used to identify antibodies, which are proteins made by the immune system to fight foreign substances, that may be present in the blood and can react with red blood cells. This test is commonly performed during pregnancy, before blood transfers, or when investigating unexplained anemia. Identifying these antibodies is crucial to prevent complications such as dangerous reactions in blood transfer recipients or health issues in newborns.
