Know More About This Test

Blood Grouping and Rh typing determine an individual's blood type based on the presence or absence of specific antigens on red blood cells. The ABO system (A, B, AB, O) and the Rh factor (positive or negative) are clinically crucial for blood transfusions, pregnancy care, organ transplantation, and emergency medical situations. Incorrect blood grouping can lead to life-threatening transfusion reactions, making this test fundamental and mandatory in many medical settings.

Why Is This Test Recommended?

Blood Grouping and Rh typing is recommended to ensure safe blood transfusions, prevent transfusion reactions, assess Rh compatibility during pregnancy, and prepare for surgery or organ donation. It is required during pregnancy, planned surgery, blood donation, emergency trauma, and organ transplantation.

What Do the Results Indicate?

Results identify your blood type such as A+, O−, AB+, etc. The ABO system classifies blood based on surface antigens, while Rh typing identifies the D antigen. There is no "abnormal" result—only different blood types. Rh incompatibility in pregnancy can lead to hemolytic disease of the newborn if not managed properly.

How Is the Test Performed and Prepared For?

A blood sample is collected and tested using antigen–antibody reactions. No preparation or fasting is required. Your blood group is documented for lifelong medical reference.

Frequently Asked Questions (FAQs)

• Is blood group permanent?
  Yes; blood group is determined genetically at birth and remains constant throughout life, never changing under normal circumstances.

• Is Rh negative rare?
  Yes, less common; approximately 15% of the population is Rh negative, with variation across different ethnic groups.

• Can blood group change?
  No; blood group is genetically determined and cannot change naturally, though rare conditions like bone marrow transplant may alter typing.

• Is it required during pregnancy?
  Yes; blood grouping and Rh typing are mandatory during pregnancy to identify Rh incompatibility and prevent hemolytic disease of the newborn.

• Is fasting needed?
  No; blood grouping can be performed at any time without fasting or special preparation.

• Is this test mandatory before surgery?
  Yes; blood grouping is mandatory before surgery to ensure availability of compatible blood in case transfusion is needed during the procedure.
