Blood Typing Lab

(1) Antigens & Antibodies Membranes of RBC’s contain unique I.D. Tags (Antigens) Antigens are membrane proteins Unique antigens bind with Unique antibodies Antibody: Protein produced to bind with foreign cells to stimulate immune response of lymphocytes.

(2) Agglutination Agglutination = Binding of antigens with antibodies. Causes a clumping of factors. Looks like a thickening of blood. When blood-cell antigens bind with their matching antibodies….. AGGLUTINATION!

(5) Blood Typing Lab Purpose: Procedure: Solve the crime scene and identify the suspect Test crime scene blood and blood of all suspects (W, X & Y) Procedure: Mix blood with “Serums” (anti-A, anti-B & anti-Rh) No Agglutination = Does NOT have those antigens Agglutination = Those antigens present

(8) Rh Factor Blood Type can either be “Positive” or “Negative” for the Rh factor Agglutination with anti-Rh Serum = Rh+ No Agglutination with anti-Rh Serum = Rh-
