Question

What will happen if blood from a Rh-ve person is exposed to the blood from a Rh+ve person?​

• A. -ve and +ve Rh-antigen cancel out each other​
• B. Nothing will happen​
• C. Antibody will form​
• D. Antigen formation takes place​

Answer 1

The correct option is C Antibody will form​

Correct answer: (d) Antibody will form​
$\bullet$ When the blood of an individual (Rh positive) is transfused into people lacking it (Rh negative), the blood of the recipient develops an antibody for Rh substance within two weeks of transfusion. ​
$\bullet$ Now, if a second transfusion be given to such Rh-negative person, the antibody produced by the first transfusion causes a reaction with the transfused blood, which may even lead to death.
