Interpretive Data:
Vectra DA measures 12 biomarkers and combines them into a single
disease activity score to assess the key mechanisms and pathways that
drive rheumatoid arthritis (RA) disease activity. Measured biomarkers
are adhesion molecule VCAM-1, growth factors EGF and VEGF-A, cytokine-
related proteins IL-6 and TNF-RI, matrix metalloproteinases MMP-1 and
MMP-3, skeletal-related protein YKL-40, hormones Leptin and Resistin,
and acute phase proteins SAA and CRP. Clinical interpretation of
individual biomarker levels, which have different weights in the
Vectra
DA algorithm, has not been established.
Vectra DA was validated in adults 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.
