antiglobulin test?
Coombs Control check cells - Answers What reagent helps tell you that AHG was added and it was active
and the washing was adequate in the antiglobulin test?
LISS - Answers What potentiator reduces ionic strength so agglutination between antigen and antibody
uptakes at a faster rate?
PEG - Answers What potentiator removes water molecules in the test environment to allow for
antigen/antibody attraction?
Rh, Kidd, Lewis, P1, I - Answers Proteolytic enzymes enhances these antigens?
Duffy, MNS, Xga - Answers Proteolytic enzymes destroys these enzymes?
Monoclonal-Polyclonal Blend - Answers What D reagent is used more often that is a hybridoma
