Immunoassay Testing

Interferences in Immunoassays, Part 1

Substances that alter the measurable concentration of the analyte or antibody (Ab) binding result in immunoassay interference. Interferences can be of 2 types – analyte dependent and analyte independent.

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.
