Summary Introduction
Introduction:
Influenza virus is of four types. It causes seasonal fever in humans. When the influenza virus is seen in a serum of sheep red blood cells and anti-sheep red blood cells, then the patient will produce an antibody against the influenza virus. Hem agglutination inhibition occurs.

a.
You cannot donate only plasma.
b.
The anti-A antibodies in the plasma of patient 4 would agglutinate with the antigens on the RBC of patient 1.
c.
It would be a safe donation because no agglutination would occur.

red blood cells are lysed, spilling hemoglobin out of the red blood cells
b.
plasma antibodies cause red blood cells to clump
c.
plasma antibodies recruit white blood cells to attack red blood cells

free hemoglobin in the plasma is harmless
