Blood-based assays at three decision points in the MS workflow, replacing or complementing imaging and CSF analysis at a fraction of the cost.

One platform, three markets
Misdiagnosis between MS and NMO can be catastrophic — NMO is worsened by standard MS therapies. BIRT reads the underlying B-cell biology of NMO to catch cases the AQP4-IgG CBA misses (~25% of NMO is seronegative).
The RRMS→SPMS transition is currently invisible. Neurologists wait 2–5 years for retrospective clinical confirmation while irreversible damage accumulates. BIRT provides a prospective molecular signal — annual screening, mammography analog.
Before MRI, a $300 blood draw rules out MS with NPV > 98%. A high-sensitivity screen that avoids unnecessary $4,000 MRIs and shortens the 4–7 year diagnostic delay.
One blood draw, three actionable clinical results
