Abstract
Performances of participants for the detection and measurement of rheumatoid factor on 18 consecutive CAP [College of American Pathologists] survey specimens are tabulated. All reagents used by participants performed well qualitatively on the positive and negative specimens. Quantitation of positive specimens by titer and IU demonstrated prominent interlaboratory variance.
