Abstract
The performance of participants in 9 consecutive College of American Pathologists (CAP) Survey specimens during 1979-1981 are listed for IgA, IgG and IgM. The majority of participants used either radial immunodiffusion (RID) (51.4%) or nephelometric kits (33.6%) manufactured by major firms and reported results in mass units (93.5%). When tabulated by kit, prominent differences in performance were noticed. Definite trends in methods employed were evident during the 2-yr period.
