People with Group O blood
are universal blood donors
are universal blood recipients
are always Rh-positive
are always Rh-negative
have A &B antigens on their RBC
In an indirect ELISA, you are measuring the patient’s
specific antigen levels
antibody levels to a specific antigen
total white blood cell count
total red blood cell count
total lymphocyte count
T cells can only recognize
denatured antigen on the cell surface
antigens in their native conformation on the cell surface
peptide fragments of antigens associated with antibody on the cell surface
peptide fragments of antigens associated with complement components
peptide fragments of antigens associated with MHC
All of the following are associated with non-specific (innate) immunity except
macrophages
complement
neutrophils (PMN)
T lymphocytes
lysozyme
The common component in all 3 complement systems is:
C1
C2
C3
C4
C1q
Antibodies can do all of the following except
agglutinate antigens
recognize intact antigens
neutralize toxins
precipitate intracellular antigens
