We assayed rheumatoid factor by instrumental latex particle counting. The calibration curve ranged from 12.5 to 500 int. units/mL. Maximal within- and between-assay CVs were 5 and 11%, respectively. Analytical recoveries ranged from 92.4 to 108%, and the relation between results and dilutions was linear in the range of 15 to 400 int. units/mL. Correlation… CONTINUE READING
