When Testing Donated Blood for Compatibility You Would Find a Person

Question

When testing donated blood for compatibility you would find a person with O type blood
A)has O type antigens on their red blood cells.
B)will lack plasma antibodies to A and B type antigens.
C)will lack A and B red blood cell antigens.
D)lacks HLA and MHC antigens.
E)will have anti-O antibodies in their plasma.

Accepted Answer

A person with O type blood lacks both A and B red blood cell antigens, making their blood compatible with those with A, B, AB, or O blood types. They may have anti-A and anti-B antibodies in their plasma, but not anti-O antibodies. HLA and MHC antigens are separate from blood type antigens and not directly related to blood compatibility testing.
