Indications for Use
The Access 25(OH) Vitamin D Total assay is a paramagnetic particle, chemiluminescent immunoassay for the quantitative determination of total 25-hydroxyvitamin D [25(OH) vitamin D] levels in human serum and plasma using the Dxl Access Immunoassay Analyzers. Results are to be used as an aid in the assessment of vitamin D sufficiency.
Device Story
Access 25(OH) Vitamin D Total assay is a competitive binding immunoenzymatic assay; utilizes paramagnetic particles and chemiluminescence. Input: human serum or plasma samples. Process: automated analysis on Dxl 9000 Access Immunoassay Analyzer; competitive binding reaction; chemiluminescent signal detection. Output: quantitative concentration of total 25-hydroxyvitamin D (ng/mL). Used in clinical laboratory settings by trained personnel. Healthcare providers use results to assess patient vitamin D sufficiency status, aiding clinical decision-making regarding supplementation or monitoring.
Clinical Evidence
Bench testing only. Method comparison study (n=150) showed R=0.97, slope 1.05 (95% CI 0.99-1.10). Precision study (CLSI EP05-A3) demonstrated within-lab CV 4.3%-9.0% for concentrations >15 ng/mL. Linearity verified 7.0-120 ng/mL. LoB=2.5 ng/mL, LoD=4.5 ng/mL, LoQ=7.0 ng/mL (CLSI EP17-A2).
Technological Characteristics
Paramagnetic particle, chemiluminescent immunoassay. Competitive binding principle. Automated operation on Dxl 9000 Access Immunoassay Analyzer. Measuring range 7.0-120 ng/mL. Traceable to NIST-Ghent ID-LC-MS/MS. Reagents include reagent pack, calibrators, Lumi-Phos PRO substrate, and wash buffer.
Indications for Use
Indicated for quantitative determination of total 25-hydroxyvitamin D in human serum and plasma to aid in assessment of vitamin D sufficiency.
