Does the MSDA Test replace MRI?

No, The MSDA Test does not replace MRI. The MSDA Test is designed to complement MRI by providing biological insight, with a quantitative blood-based view of disease activity, that MRI imaging alone cannot capture.

What makes the MSDA Test different from single-biomarker approaches?

The MSDA Test is the first and only multi-protein blood test designed specifically for MS, producing a quantitative score that indicates low, moderate, or high disease activity. The MSDA Test measures 18 biomarkers across 4 biological pathways, providing a comprehensive view of disease activity rather than a single marker.
