Tosoh Launches Vitamin D Assay

Tosoh Bioscience, Inc. introduces the ST AIA-PACK 25-OH Vitamin D assay for use on Tosoh AIA System Analyzers*. Vitamin D measurement is intended as an aid in the determination of Vitamin D sufficiency.

Vitamin D Product Focus: Don’t Underestimate Vitamin D

25-OH Vitamin D is a challenging analyte to accurately measure in human blood due to presence of 25-OH Vitamin D2, Vitamin D binding proteins and Vitamin D metabolites. Variability between different methods due to lack of standardization has added to the challenges. The Tosoh ST AIA-PACK 25-OH Vitamin D assay correlates well with gold standard methods and measures equimolar concentrations of 25-OH Vitamin D2 and D3.
