The absence of anti-A and anti-RH agglutinin plasma means that the subject is:
- a- A+ve or AB+ve
- b- A-ve or AB-ve
- c- B+ve or AB+ve
- d- Type O.
The correct answer is (d- Type O).
The absence of anti-A and anti-RH agglutinin plasma means that the subject's red blood cells do not have A or RH antigens on their surface. This can only be true for people with type O blood, which does not have either A or RH antigens.
Option a- A+ve or AB+ve:
is incorrect because people with A+ve or AB+ve blood have anti-A agglutinin in their plasma.
Option b- A-ve or AB-ve:
is incorrect because people with A-ve or AB-ve blood have both anti-A and anti-RH agglutinin in their plasma.
Option c- B+ve or AB+ve:
is incorrect because people with B+ve or AB+ve blood have anti-B agglutinin in their plasma.
