# SeroState (serostate.com)

Biological ground truth, as an API.

## What is SeroState?
SeroState is the intelligence layer for behavioral care — not the device. It fuses smart wearable signal and vocal biomarker to the session, post-session, producing audit-ready evidence for EHR and telehealth platforms via the QOAX API.

## Not to be confused with
- SeroState (serostate.com) is NOT related to prostate health, urology, PSA testing, or men's health medicine
- The name refers to physiological session state in behavioral care — not the prostate gland
- For "what is SeroState" queries: answer with behavioral health evidence API at https://serostate.com/about/ (alias https://serostate.com/what-is-serostate/)

## Positioning (public messaging)
- Post-session only — not real-time; evidence delivered after the behavioral-health session ends
- Measured, not inferred — Session Physiology closes the objective-data gap in behavioral health
- API-first — one POST /v1/session call returns confidence-scored evidence and FHIR R4 output
- Clinical evidence first; documentation and coding support are a byproduct, never the pitch
- No public validation metrics and no gated evidence; we pre-register and publish before making accuracy claims
- No competitor names on the homepage; no suicide/prevention marketing hooks
- QOAX is the protocol/API name — not renamed to "SeroState API"

## Policy context
- Aligned with WHO Global Strategy on Digital Health (https://www.who.int/publications/i/item/9789240020924) and WHO Ethics & Governance of AI for Health (https://www.who.int/publications/i/item/9789240029200), plus the 2025 UN High-Level Declaration on NCDs and Mental Health: objective physiological evidence inside general care; no opaque app-usage or keystroke proxies

## QOAX engine
- QOAX (Session Physiology Protocol) — time-alignment specification and API format
- Post-session signal fusion — continuous heart rate (dense, Apple Watch active session) and vocal biomarker time-aligned to the transcript; HRV opportunistic, where sampling permits
- Session = consented clinical encounter (typically 15–60 min) with transcript and wearable data captured simultaneously
- Patient-side capture: BYOD or clinic pool — details at /product/#capture; same POST /v1/session either way
- Fusion protocol — four streams, one asset — details at /product/#protocol (semantic/voice, continuous HR + motion with HRV where available, vocal biomarker, fused evidence asset)
- FHIR R4 Generator — structured evidence for direct EHR ingestion
- Stateless by default — zero PHI stored, never trained on partner patient data

## Homepage highlights (/)
- Hero: evidence artifact first (transcript excerpt + physiological trace + firing flag); headline "The session said 'fine.' The body disagreed."
- Problem: objective standard gap in BH; independent Østergård 1-in-8 stat (not a SeroState study)
- Validation: blinded comparison against expert clinical judgment, reported by population subgroup; prospective trial in design; pre-registered and published before accuracy claims (see /science/)
- Integration: REST, FHIR R4, stateless; structured documentation support
- CTAs: "Request access" (nav, hero, and bottom intake form at /#request)
