A patient came to the ER in hypovolemic shock due to massive blood loss. A blood transfusion is urgently needed. The image below shows agglutination test results using Anti-A, Anti-B, and Anti-D serums. Based on these results, what is the patient's blood type?
B negative
AB positive
A positive
O negative
The Correct Answer is C
a) B negative: If the patient had B negative blood: There would be agglutination with Anti-B,No agglutination with Anti-A or Anti-D.
b) AB positive: AB positive means agglutination with: Anti-A, Anti-B, and Anti-D.
c) A positive: Agglutination with Anti-A means the red cells have A antigens. No agglutination with Anti-B means B antigens are absent. Agglutination with Anti-D indicates the Rh factor is present, making the blood type Rh positive.
d) O negative: O negative blood has no A, B, or Rh antigens, so there would be: No agglutination with Anti-A, No agglutination with Anti-B, and No agglutination with Anti-D.
