Antibodies are not present in people with AB blood group and Rh-positive group
- Humans mainly have four types of blood group, Blood group A, Blood group B, Blood group AB and Blood group O.
- People with AB type of blood group do not have any type of antibodies present in their blood because of which they are also known as universal recipients of blood.
- However, people with Blood group AB do have the presence of anti-A and anti-B antigens in their blood.
- If Rh factor is present in the blood, it means that blood type is Rh-positive. Antibodies are formed against Rh-positive blood if it is introduced in an Rh-negative type of blood.
Thus, antibodies do not occur naturally in the blood groups of (Option 3) AB group and Rh-positive group.
