What is Blood Grouping?
The blood group of an individual is identified by the presence or absence of the specific antigen on the surface of the red blood cell and is classified under the ABO and Rh system based on the presence of Rh (D) antigen. For instance, if a person has a blood group A positive it indicates that the A antigen is present on the surface of the red blood cells along with the presence of Rh (D) antigen, and it’s the same for the rest of the blood groups as well. The common blood groups are A, B, AB, and O and each could be Rh-positive or Rh-negative.
Blood grouping is a diagnostic test for the identification of the individual’s blood group that is crucial for the blood transfusion safely, management of the pregnancies, organ transplants and severe immune reactions.
How is the Test Performed?
The Blood Grouping Test is a straightforward and fast test that involves the collection of the blood sample.
Preparation

- The blood is usually drawn from the arm.
- The procedure is not painful but a few people might feel a tingling sensation.
Laboratory Analysis
- The sample is analyzed in the laboratory by mixing it with Type A and Type B antibodies and then agglutination is observed.
- The Rh factor is determined by the anti-D antibodies.
Cross Matching
- In cases of blood transfusion cross matching is performed by mixing the donor’s blood with the recipient’s serum and then agglutination is observed.

- Rapid heart beat
- Breathing difficulties
- In severe cases shock or organ failure

It causes the disease called hemolytic disease of the newborn and it shows the following symptoms in the baby
- Severe Jaundice
