This leaflet provides usage instructions, specifications, packaging, storage, and safety information for the CRP national standard reference material (batch…
The C‑reactive protein (CRP) national standard is a lyophilized reference material produced by the National Institutes for Food and Drug Control. It is intended for accuracy evaluation of CRP assay kits, especially those based on immunoturbidimetry and chemiluminescence methods.
The standard should be reconstituted with 1 mL deionized water, mixed thoroughly, and further diluted with validated diluent as needed. It must be stored at ≤ ‑20 °C, protected from repeated freeze‑thaw cycles, and handled with biosafety precautions because it contains human‑derived material. No fixed expiration date is assigned; the material remains valid until a formal discontinuation notice is issued. This manual is written in Chinese.
