Assess Disease Activity

Vectra® DA provides a comprehensive measure of RA disease activity

Vectra DA measures 12 biomarkers and combines them into a single score to assess the key mechanisms and pathways that drive RA disease activity.


An initial Vectra DA score provides an objective, quantitative starting point to track RA disease activity over time with subsequent testing. A single score classifies RA disease activity. Vectra DA scores range from 1 to 100 and categorize RA into low, moderate or high disease activity
