Blood Group and Rh Inferred Panel (ABO/Rh Typing)
This test helps determine your blood type (A, B, AB, or O) and Rh factor (positive or negative), which is essential for safe blood transfusions and pregnancy care.

What This Test Measures
The test detects specific antibodies and antigens in your blood to identify your ABO group (A, B, AB, or O) and Rh factor (positive or negative). This is done through a simple blood sample drawn from your arm.
Why It Matters for Blood Transfusions
If you ever need a blood transfusion, your blood type ensures the donated blood is compatible with yours to prevent dangerous reactions. This panel also helps doctors plan safe pregnancies.
Common Uses in Healthcare
This test is routinely checked during pregnancy to prevent complications like hemolytic disease of the fetus and newborn. It’s also used before surgeries, organ transplants, or blood transfusions to prevent mismatches.
Sample Collection and Preparation
A small amount of blood is taken from your arm using a needle. The blood is then processed in a lab to detect your blood type and Rh factor using specialized techniques like agglutination (clumping) or immunoassay methods.
Reference range
Adult males: 13.5-17.5 g/dL; Females: 12.0-16.0 g/dLN/A
No special preparation usually required. Stay well hydrated. Inform your healthcare provider of all medications and supplements you are taking.
