Cat. # 20001VDCK · 5 × 0.6 mL · −80 °C · For In Vitro Diagnostic Use
25-OH Vitamin D Quality Control
5-level human serum kit · CDC reference-lab assigned values
Human-serum quality control for immunoassay and LC-MS/MS laboratories that already measure 25(OH)D and need accuracy monitoring — values tied to the CDC reference measurement procedure, not only imprecision checks.
- End levels assigned by the CDC Vitamin D reference laboratory (isotope-dilution LC-MS/MS RMP, NIST SRM–calibrated) — not a peer-group mean
- Five levels across the reportable range; intermediate levels prepared from the CDC-assigned anchors
- Dedicated 25(OH)D kit — not a multi-analyte cocktail
- Cat. # 20001VDCK on the box and on each vial
Peer-group or cocktail QC can look in-range while the method is still off versus a reference measurement procedure. Insert values on this kit are traceable to the CDC Vitamin D reference laboratory’s isotope-dilution LC-MS/MS procedure (calibrated to NIST SRM) — the same reference hierarchy used in VDSCP — not a peer-group average. Solomon Park is not CDC-endorsed; the certificate states the assignment.
