INTENDED USE
K-ASSAY ®   CRP (3) is intended to be used as a high-sensitive assay for the quantitative determination of CRP in serum and plasma by immunoturbidimetric assay.   Measurement of C-Reactive Protein aids in the detection and evaluation of tissue injury, inflammatory disorders, and related diseases.
FOR IN VITRO DIAGNOSTIC USE.

REAGENT PREPARATION
The reagents are ready to use and do not require reconstitution.  Mix gently before using.

STORAGE AND HANDLING
All reagents should be stored at 2-8°C and protected from light.  Unopened reagents can be used for 18 months from the date of manufacture as indicated on the expiration date on the package and bottle labels. Once the reagent vial has been opened, store tightly capped at 2-8°C and use within 1 month.

PERFORMANCE
Precision
The following data was obtained using a Hitachi 917 analyzer and standard protocol.   Samples tested were commercial human CRP control serum.
