[Particle enhanced immunoturbidimetic assay of high sensitive C-reactive protein].

Objective: To evaluate the particle enhanced immunoturbidimetic assay of high sensitive C-reactive protein by the automated chemistry analyzer (Hitachi 7170A).

Methods: The detection limit of quantification, measurement range, precision, interference and reference interval were assessed.

Results: The measurement range of the method was from 0.125 to 12.5 mg/L. The detection limitation was 0.115 mg/L. The internal and external accuracy were 0.89% and 0.90% respectively. The reference range of the assay was from 0.20 mg/L to 2.60 mg/L.

Conclusion: The particle enhanced immunoturbidimetic assay is sensitive and stable, and can be used in clinical diagnosis.
