NIST SRM 967b is SI-traceable primary human serum creatinine certified reference material issued Sep 29 2023, valid until Aug 30 2030.
Dual-Level Frozen Human Serum Creatinine Each kit contains 2 low-level + 2 high-level frozen serum vials, 1 mL per vial. All donor serum tested non-reactive for HIV, HBsAg, HCV under FDA-approved assays, classified BSL-2 human matrix with full ethical approval. Certified creatinine values in 3 SI-aligned units (μg/g, mg/dL, mmol/L) with 95% expanded uncertainty for both levels; certified serum density at 23℃ and molar mass of creatinine with individual uncertainty components are provided for full conversion calculation.
NIST SRM 967b Certified values derived from inter-laboratory statistical evaluation complying with JCGM GUM. Shipped on dry ice; long-term storage at -80℃ dark, thaw fully at 20–25°C and use immediately, repeated freeze-thaw prohibited. Intended solely for in-vitro creatinine assay validation & in-house control material assignment; clinical diagnosis, human/animal in-vivo administration, unauthorized resale are strictly forbidden.
Dual-Level Frozen Human Serum Creatinine All waste serum and vials must be autoclaved as biohazard waste. Full supporting documents include COA and NIST SP 260-239 collaborative study publication with raw chromatograms, homogeneity & long-term stability data.
human serum creatinine certified reference material Ideal for clinical biochemistry labs, IVD creatinine kit manufacturers, GLP toxicology and academic nephrology research worldwide. Authorized distributors offer dry ice hazardous material import documents and formal tax invoices for bulk laboratory orders.
