Vectra DA — the only multi-biomarker blood test validated to measure RA disease activity

Vectra DA provides an objective and reproducible measure of RA disease activity in both seropositive and seronegative RA patients.13

The concentrations of 12 serum proteins are measured. An algorithm is then applied to calculate a single Vectra DA score ranging from 1 to 100 that categorizes RA into low, moderate, or high disease activity.

Vectra DA can provide a baseline assessment of RA disease activity and track it over time. Vectra DA is validated for use in adults diagnosed with RA.

*Vectra DA thresholds were derived by converting the DAS28CRP scale (0-9.4) from Inoue et al14 to the Vectra DA scale (1-100).
