OBJECTIVE: To develop a sensitive, accurate detection method for high sensitive C-reactive protein (hsCRP).
METHODS: With the GoldMag particle as the solid phase carrier, horseradish peroxidase (HRP)-lunimo-H2O2 as the chemiluminescence reaction system, we established a chemiluminescent immunoassay for hsCRP detection. Linear range, sensitivity, precision, accuracy and other indicators were evaluated. hsCRP level of 233 clinical human serum specimens were determined and compared by two different methods: the GoldMag particle-based magnetic chemiluminescence enzyme-linked immunoassay established in this study, and the commercialized scattering immunoturbidimetric assay from Germany SIEMENS.
RESULTS: The chemiluminescent immunoassay for hsCRP based on GoldMag particle had a good linear relationship between 0.15 mg/L and 25 mg/L (R(2)=0.9937), with the detection limit of 0.076 mg/L. The intra-assay precision was less than 10.00% and the inter-assay precision was less than 15.00%. The average recovery rate for accuracy was 97.80%. In the contrast experiment of 233 clinical human serum specimens, the results obtained using the approach established in this study showed a high correlation and consistency with scattering immunoturbidimetric assay from Germany SIEMENS.
CONCLUSION: GoldMag particle-based magnetic chemiluminescence enzyme-linked immunoassay for hsCRP has been successfully developed.
