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.

Regulatory Posture applies to this provider. Its tags matched the Health regime, so Regulatory Posture carries 15 points of the composite. If this regime is wrong for your business, say so on your provider repo — the applicability map is public and we will correct it.

The six quality facets above are damped to 85 points between them, because the conditional facet above carries the other 15. That is why each facet's contribution is shown against a damped maximum: raising a quality facet moves the composite by 85% of its nominal weight, not 100%. The full arithmetic is at apis.io/rating/.
