The absence of anti-A and anti-RH agglutinin plasma means that the subject is.. A+ve or AB+ve

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.
