what is vectra da

Vectra DA is an advanced blood test for adults with rheumatoid arthritis (RA). It helps you and your doctor better understand your RA disease activity.

Vectra DA blood test for RA gives a more complete look at your disease activity by measuring 12 markers of RA disease activity. Some other tests, such as C-reactive protein (CRP) and erythrocyte sedimentation rate (ESR or “sed rate”), only measure one marker.

Vectra DA test scores can help track your disease activity over time with an objective measure that complements your doctor’s exam and your own assessment.

Patients with high Vectra DA scores have been shown to be at a higher risk for rheumatoid arthritis-related joint damage than patients with low or moderate Vectra DA scores. Vectra DA scores have identified patients with a high risk of future joint damage better than CRP or ESR.

Knowing your risk for joint damage can help you and your doctor assess the treatment plan that’s right for you.

Vectra DA has not been validated or studied for diagnosing RA. It has not been studied for use in predicting which specific therapy or class of therapy will work for you
