Product Focus - Vitamin D

Dec. 22, 2020

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.

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.

Chemiluminescent Enzyme Immunoassay

Lumipulse G 25-OH Vitamin D is a Chemiluminescent Enzyme Immunoassay (CLEIA) for the quantitative determination of 25- hydroxyvitamin D (25-OH vitamin D) and other hydroxylated vitamin D metabolites in human serum and plasma (sodium heparin, lithium heparin, or dipotassium EDTA) on the LUMIPULSE G System.


Vitamin D Control

The Complete D 25-OH Vitamin D Control is compatible, without the need for dilution, on major immunoassay platforms. Values are also provided for LC-MS/MS. The product features a 3-year refrigerated shelf-life from the date of manufacture and extended open-vial stability of 12-months at 2ºC–8ºC and one month at room temperature.



The Acusera Immunoassay Premium Plus comprises 54 analytes including Vitamin D. The combination of routine tumour markers, therapeutic drugs and Vitamin D allows laboratories to dramatically reduce the number of controls required while ultimately keeping costs to a minimum. It is compatible for use with the Acusera 24.7 real-time data management program.
