Molecular Stethoscope

Molecular Stethoscope (now operating as Superfluid Dx, Inc.) is a South San Francisco clinical-stage diagnostics company developing minimally invasive blood tests for neurodegenerative disease. Its cell-free messenger RNA (cf-mRNA) liquid-biopsy platform aims to detect Alzheimer's disease at early stages from a routine blood draw, as an alternative to spinal taps and brain imaging. Surfaced as a portfolio company of dcvc and added to the API Evangelist network. As a clinical diagnostics R&D company it publishes no public developer API, documentation, or technical platform; this profile is maintained for network completeness rather than API discovery.

Molecular Stethoscope is profiled on the APIs.io network. Tagged areas include Company, Diagnostics, Healthcare, Life Sciences, and Alzheimers.
