A blood sample from a person named 'X' is tested with different antisera. It shows agglutination with Anti-B serum and Anti-D (Rh) serum, but no agglutination with Anti-A serum. Which of the following groups of individuals can safely receive a blood transfusion from person 'X'?
Options
- AB Rh ⁻ and AB Rh ⁻
- BA Rh ⁺ and O Rh ⁺
- CB Rh ⁺ and AB Rh ⁺
- DB Rh ⁺ , B Rh ⁻ , O Rh ⁺ and O Rh ⁻
Correct answer
C. B Rh ⁺ and AB Rh ⁺
Step-by-step solution
Agglutination with Anti-B serum indicates the presence of B antigens, and agglutination with Anti-D serum indicates the presence of Rh antigens. The lack of agglutination with Anti-A serum means A antigens are absent. Thus, the blood group of person 'X' is B Rh ⁺ . A donor with B Rh ⁺ blood can only donate to recipients who do not have anti-B antibodies and who can tolerate Rh ⁺ blood. These compatible recipients are B Rh ⁺ and AB Rh ⁺ . Options with Rh ⁻ recipients are incorrect because they would develop anti-Rh
