What is Vectra?
Vectra is an advanced blood test for adults with rheumatoid arthritis (RA). It helps you and your doctor better understand your RA disease activity.
Vectra 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 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 scores have been shown to be at a higher risk for rheumatoid arthritis-related joint damage than patients with low or moderate Vectra scores. Vectra 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 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.Download the patient guide

How does the Vectra Blood Test Measure RA Disease Activity?
Vectra detects what’s going on below the surface by assessing multiple biological pathways that drive RA disease. Vectra provides information about RA that goes beyond physical symptoms. The test measures the levels of 12 markers in your blood, called “biomarkers,” that have been linked to RA inflammation. The 12 biomarkers are combined into a single score between 1 and 100 that indicates your current level of RA disease activity. The single score generated by Vectra classifies RA into low, moderate, and high disease activity – the lower the score, the better.Learn more
