Vectra® with CV Risk

Also known as: Vectra® DA Disease Activity Test

Clinical Use

Order Test

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.

Special Instructions

Not provided.

Limitations

The individual biomarker results are intended for use in the generation of the Vectra score only and should not be used interchangeably with results generated by different methodologies. Clinical interpretation of individual biomarker levels, which have different weights in the Vectra algorithm, has not been established. This test has not been cleared or approved by the Food and Drug Administration (FDA).
