Rapid quantification of C-reactive protein by centrifugal analysis.
I describe a rapid, simple immunoturbidimetric method for determining C-reactive protein in serum. With the Instrumentation Laboratory Multistat III microcentrifugal analyzer, quantitative results are obtained automatically after a few minutes of reaction time. Within-run and between-run coefficients of variation ranged from 2.5 to 12.7% at C-reactive protein concentrations of 55 to 69 and 14 to 25 mg/L, respectively, normal values being less than 10 mg/L. Comparison with the commercially available radial immunodiffusion method (y) yields the regression equation y = 1.011x - 2.112 (r = 0.979, n = 100).
