Test Details
Use
Vectra® DA measures the concentration of 12 serum proteins. An algorithm is applied to these concentrations to calculate a quantitate disease activity score ranging from 1 to 100. Test results are intended to aid in the assessment of disease activity in RA patients when used in conjunction with standard clinical assessment. This test is not intended or validated to diagnose RA.
An order for Vectra® DA includes and requires an order for 12 biomarkers: VCAM-1, EGF, VEGF-A, IL-6, TNF-RI, MMP-1, YKL-40, Leptin, Resistin, SAA, CRP. These 12 biomarkers are required to generate the Vectra® DA test score. By ordering Vectra® DA, you are ordering all 12 biomarkers and are acknowledging that Labcorp cannot provide a Vectra® DA test result without these 12 biomarkers. Vectra® DA was validated in adults with Rheumatoid Arthritis (RA).
