Evaluation of immunoturbidimetric method for measuring serum c-reactive protein

Objective To evaluate the performance characteristics of the immunoturbidi-metric assay for Measurement of C-reac-tive Protein.Method The reproducibility and linearity of the method were determined.A method comparison study was performed using an single diffusion test as the reference test.Results The linearity range was found0.33～42mg /L.Reported values above42mg /L should be diluted and reanalyzed.The coefficients of variation were below5%.The comparison with the single diffusion test showed a good correlation coefficient (r=0.976,CRP values from2.77～28.65mg /L).Conclusion The method is easy to perform,ac-curate,fully automated,and suitable for analyzing a small number of samples.
