INTENDED USE
For the in vitro quantitative determination of C-reactive protein (CRP) in human serum and plasma on automated clinical chemistry analyzers.  Measurement of CRP is of use for the detection and evaluation of inflammatory disorders and associated diseases, infection and tissue injury.
For in vitro diagnostic use only.

REAGENT PREPARATION
1. The K-ASSAY ®   hsCRP reagents are provided ready-to-use.
2. Physiological saline is needed to dilute high CRP samples and is used as a zero calibrator.

STORAGE AND HANDLING
The K-ASSAY ®   hsCRP assay reagents should be stored at 2-8°C.  DO NOT FREEZE.  The reagents are stable when stored as instructed until the expiration date of the label.   Do not mix reagent components from different lots.

PERFORMANCE
Precision
The intra-precision of the K-ASSAY ®   hsCRP Assay was evaluated as follows: in the study, three serum controls containing CRP were tested in duplicates on a Hitachi 917 over 20 days with 2 runs per day.
