How do slides with sickle cell anemia look?
They have sickle-shaped RBCs scattered
Difference between sickle-celled and normal RBCs?
The sickle-celled RBCs get sticky and clump together
What are antigens?
They make your blood type
What are antibodies?

What is agglutination?
Clumping of antibodies to antigens in blood
What is agglutinogen?
Antigen
What is agglutinin?
Antibodies/gamma immunoglobins
What are transfusion reactions?
Adverse reactions to transfusions of blood, like infection and sickness
What is the difference between agglutination and coagulation?
Agglutination is a clump in the blood, coagulation is a full platelet plug and then clot
