Test Result image v4Regular, precise assessments of RA disease activity, as recommended by EULAR and ACR, are important to improving patient outcomes1, 2, 3. Vectra DA – the only multi-biomarker blood test validated to measure RA disease activity– provides an objective and reproducible measure of disease activity in both seropositive and seronegative patients4. Vectra DA simultaneously measures 12 proteins consistently associated with RA disease activity, integrating them into a single, quantitative score to help inform patient management decisions.

This presentation will review the potential clinical applications of Vectra DA in the management of RA, with a specific focus on findings from recent studies presented at the Annual Rheumatology Meeting held in DC.

Potential clinical applications of Vectra DA include:

  • Tracking changes in disease activity over time (baseline assessment and on-going tracking)
  • Measuring RA disease activity in response to change in therapy
  • Assessing RA disease activity in patients with common comorbidities
  • Clarifying RA disease activity when clinical disease assessment may be challenging (symptoms vs. labs, MD vs. patient assessment)
  • Facilitating discussion with patients reluctant to change treatment
  • Identifying unsuspected disease activity

Vectra DA is validated for use in adults diagnosed with RA. 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.

Vectra™ DA

Vectra DA is the only multi-biomarker blood test for rheumatoid arthritis (RA) disease activity that integrates 12 key proteins consistently associated with RA disease activity into a single objective score to help physicians make more informed treatment decisions. Vectra DA testing is performed at Crescendo Bioscience’s state-of-the-art laboratory and test results are reported back within 7-10 days. Physicians can receive test results via standard mail, fax or via a private web portal, VectraView. Vectra DA is available in the U.S. in 49 states and pending laboratory licensure in NY.
