What is universal blood type

Minor antigens other than A, B, and Rh that occur on red blood cells can sometimes also cause problems. So they are also checked for a match before giving a blood transfusion. Serious transfusion reactions are rare today because of blood type tests.

Rh blood type checks for the Rh antigen also called the Rh factor on red blood cells. If your red blood cells:. If your blood has the B antigen but not the Rh antigen, your blood type is B-negative B—. Rh blood type is even more important for pregnant women. A problem can occur when a woman who has Rh-negative blood becomes pregnant with a baby fetus that has Rh-positive blood.

This is called Rh incompatibility. If the blood of an Rh-positive baby mixes with the blood of an Rh-negative mother during pregnancy or delivery, the mother's immune system makes antibodies. This antibody response is called Rh sensitization and, depending on when it occurs, can destroy the baby's red blood cells. Rh sensitization does not generally affect the health of the baby during the pregnancy in which the sensitization occurs. But the health of a baby with Rh-positive blood during a future pregnancy is more likely to be affected.

After sensitization has occurred, the baby can develop mild to severe problems called Rh disease or erythroblastosis fetalis. In rare cases, if Rh disease is not treated, the baby may die. An Rh test is done in early pregnancy to check a woman's blood type. If she is Rh-negative, she can get a shot of Rh immunoglobulin that almost always prevents sensitization from occurring. Problems from Rh sensitization have become very rare since Rh immunoglobulin was developed.

In general, there's nothing you have to do before this test, unless your doctor tells you to. A health professional uses a needle to take a blood sample, usually from the arm.
