Vitamin D testing and the use of vitamin D supplements is commonplace in the United States. A common, though not universal, treatment goal for vitamin D supplementation is 25(OH)D level of ≥50 nmol/L or ≥20 ng/ml.
Vitamin D Assay
This Access 25(OH) Vitamin D Total assay detects 25(OH) vitamin D2 and 25(OH) vitamin D3, eliminating the need for multiple tests or sample reruns. The assay is aligned with the Ghent University 25(OH) standard and is scalable across all Beckman Coulter immunoassay analyzers.
Beckman Coulter
Quantitative Test
The EZ Vitamin D assay is intended for use in clinical laboratories for the quantitative determination of 25-OH vitamin D in human serum and plasma, using automated chemistry analyzers. The EZ Vitamin D assay requires no sample pre-treatment or pre-dilution steps and recognizes both 25-OH Vitamin D2 and D3 equally.
