[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.


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