FHIR-Compliant · Lab Data Infrastructure

Lab data
you can trust.

Validor ingests lab analyzer output, validates against business rules, normalizes to FHIR, and persists with full provenance — deterministically, atomically, every time.

Data Flow
From raw CSV to FHIR resources
Every file travels a deterministic path — parsed, validated, normalized, and persisted. No partial writes, no surprises.

Key Properties
Built-in guarantees
Six core properties that make Validor reliable for healthcare data workflows.
🔒
Idempotency
Ingestion uniqueness enforced by (instrument_id, run_id) constraint. Resubmit the same file — nothing changes.
🔍
Deduplication
SHA-256 content hash detects exact duplicates. Mismatched hashes for the same key are rejected before touching the database.
⚛
Atomicity
Validation or normalization failures produce no partial writes. Raw data is always persisted; derived resources only on full success.
📐
Determinism
Same input always produces same output. All transformations are reproducible — no hidden state, no runtime variance.
🕐
Auditability
Every processing step recorded as a timestamped event with status. Full provenance chain from raw upload to persisted FHIR resource.
📊
FHIR R4 Output
Lab results persisted as DiagnosticReport and Observation resources, ready for downstream healthcare systems.

Two scenarios: a valid file completing the full pipeline, and an invalid file caught at validation.
✓ Valid CSV
✗ Invalid CSV

Provenance
Full audit trail, by design
Every ingestion emits a timestamped event log. Every step. Every outcome. Built-in, not bolted-on.
