This is an agglutination test used to determine the blood group (ABO) as well as Rh factor. This test is useful for the screening of blood for transfusion purposes, for typing of pregnant mother and baby to cope with complications of hemolytic diseases. Similarly, determination of Rh factor is important in prenatal and postnatal patients. This test is also recommended in case of organ donor as HLA as well as ABO/Rh compatibility is critical. Other situations when this test is widely used is in diseases like anemia, thalassemia and hemophilia and trauma or accidental blood loss.
It’s important that ABO Grouping and Rho (D) Typing test be done before blood transfusions and organ donor procedures since incompatibility of blood could lead to complications such as blood clumping, also called as agglutination. This is a fatal condition that could lead to death. Imagine your body treating the donated blood as a pathogen and attacking it.
As for mothers and fetuses, ABO Grouping and Rho (D) Typing test can easily detect if the mother and the fetus has compatible blood and RH type. If they don’t match, the mother will be given a medication called RhoGAM, and this will help prevent the mother’s body from treating her baby as an antigen and developing antibodies against the fetus which could lead to more serious complications.
How to Prepare for an ABO Grouping and Rho (D) Typing Test
No fasting is required prior to taking the ABO Grouping and Rho (D) Typing. Only a small amount of blood is needed for testing. The area will be swabbed with alcohol to clean it, and a blood sample will be drawn. In newborn, blood sample will be taken from the umbilical cord or from the heel.
What the Results Mean
You can receive the results of the blood typing and Rho test in a few minutes. Below are the blood and Rho types and the donor blood types that they can receive:
A+ can receive blood from A+, A-, O+, O-
A- can receive blood from A- and O-
B+ can receive blood from B+, B-, O+, O-
B- can receive blood from B- and O-
AB+ can receive blood from AB+, AB-, A+, A-, B+, B-, O+, O-
AB- can receive blood from AB-, A-, B-, and o-
O+ can receive blood from O+ and O-
O- can receive blood from O-
Common ABO Grouping and Rho (D) Typing Test Questions
Is ABO Grouping and Rho (D) Typing important?
Yes. You never know when you’re going to need blood transfusions, and knowing your blood and Rho type may save your life. In any case, the health practitioners will perform this test on you prior to any procedure.
Who can receive any blood type and who can’t?
People with AB+ blood type can receive any blood and Rho type, but people with O- blood type can receive only the same type.
What are the other uses for ABO Grouping and Rho (D) Typing?
This test can also help determine who the birth parents are. For example, a woman wants to identify who her baby’s father is. Blood samples will be taken from the mother, the baby, and the possible fathers, and the results of the baby’s test will be checked against the possible father’s blood types. The person who closely matches that of the baby’s is the possible father. Of note, the ABO Grouping and Rho (D) Typing is more useful in proving or verifying that the man isn’t the baby’s father, rather than the opposite. For more accurate results, other tests will be done like HLA test and DNA test.
