> or = 1:32 Antibody Detected


A polyvalent conjugate (recognizing IgG, IgM and IgA) is used to detect

the presence of antibodies to Giardia lamblia.  A four-fold or greater

increase in titer between acute and convalescent sera indicates an acute

active phase.  A single positive reaction represents previous exposure,

since antibody titers are known to remain high for at least six months.
