Precision

This rapid assay will present a variation coefficient of around 10% at higher Vitamin D concentrations and around 30% at lower Vitamin D concentrations. This makes the assay best suited for Vitamin D deficiency screening purposes.

Method Comparison

Commercially available Vitamin D assays tend to correlate relatively poorly amongst each other.

The LumiQuick Quick Profile™ test has been standardised using so-called NIST standards, for which value assignment was done with a Liquid chromatography–mass spectrometry (LC/MS) method.

When subsequently comparing clinical samples over the complete measuring range of the assay, the following correlation is found between the LumiQuick Quick Profile™ test and LC/MS :
