Guideline-aligned
Every recommendation maps to the NCSP HPV Primary pathway — Figures 1–10 and Table 1 — inside a versioned, test-covered decision engine.
Cervical Referral Grading Tool · by Privexa
Referral grading & screening decision support, governed end to end.
CerviGrade by Privexa helps hospital screening and colposcopy teams turn referral and lab data into provisional, guideline-aligned recommendations — each one reviewer-gated, auditable, and mapped to the NCSP HPV Primary pathway. Decision support designed for clinicians, not autonomous care.

Why CerviGrade
Built for clinical trust, not just throughput
The hard part of screening at scale isn't speed — it's confidence. Every surface in the platform is designed so a clinician can trust, check, and stand behind the output.
Reviewer-gated by design
Outputs are provisional. A clinician confirms before any action — the platform never acts on its own.
Equity from day one
Outcomes are disaggregated by ethnicity in NZ Level-1 priority order, so inequities are visible — not buried in an average.
Source-to-decision audit
Each result carries its source, mapping and engine version, with a full step-by-step decision trace.
How it works
From referral to reviewed recommendation
A single governed pipeline. The data source can change — the validation, decision engine and audit stay exactly the same.
Step 1
Ingest
CSV, Excel or JSON today; HL7 v2 / FHIR R4 adapters defined for later.
Step 2
Validate
NHI, enum and consistency checks with clear, fix-it guidance per row.
Step 3
Decision support
The shared engine produces a provisional, guideline-aligned recommendation.
Step 4
Reviewer confirmation
A clinician reviews and confirms before anything is actioned.
Step 5
Audit & export
Every case stays traceable, with full source and engine metadata.
Platform
One governed platform, many surfaces
Batch and manual, validation and equity, integration and audit — all sharing the same decision engine and the same safety guarantees.
