Development and validation of a particle-enhanced turbidimetric immunoassay for C-reactive protein

The development of a particle-enhanced turbidimetric immunoassay for C-reactive protein is described. The method demonstrates excellent precision, with the calibration curve remaining stable for at least 16 weeks. The method compares well with established techniques and there is no interference from a variety of autoantibodies, endogenous serum constituents or commonly used drugs.
