Question

Identify the blood grouping process done here.
Slide given with: AB no clumps, Clumping in O & No clumps in control. Which group does this signify?

• A. A-ve
• B. B+ve
• C. O+ve
• D. Rh group

Answer 1

The Correct Option is D

The blood grouping process described involves determining if there is clumping in the blood sample when exposed to different antibodies to identify the blood type. In this case:

• No clumps are observed with AB grouping.
• Clumping is observed with O grouping.
• No clumps are observed in the control.

These observations indicate that the characteristic being tested is the presence or absence of the Rhesus (Rh) factor, rather than a standard ABO blood type grouping. Clumping in the O group implies the presence of Rh antigens as different antibodies react with different antigens present in the sample. The absence of clumping in the control confirms the test's validity, as it shows no external factors are causing agglutination. As the scenario does not correlate with typical A, B, or O blood type reactions, it signifies the presence or absence of Rh factor, confirming the correct interpretation is the Rh group.
