Scalable · Affordable · Joint Architecture

Health screening infrastructure built to reach everyone.

SaJa is a multi-modality, standards-based architecture that takes population-scale clinical and genetic screening from sample intake to a decision support report.

The three principles of SaJa

S01

Scalable

One pipeline that runs the same from a single clinic to a national programme. Horizontal compute, containerised stages, and versioned reference panels keep throughput linear as volume grows.

  • Elastic batch scheduling
  • Versioned reference panels
  • Millions of samples / year
A02

Affordable

Cost is a design constraint, not an afterthought. Commodity sequencing, shared reference infrastructure, and open tooling drive the per-sample price toward the marginal cost of the assay.

  • Commodity sequencers
  • Shared reference compute
  • No per-seat licensing
J03

Joint

A common architecture that labs, health systems, and researchers extend together. Shared schemas and open interfaces mean a variant curated once is trusted everywhere.

  • Open interchange schemas
  • Federated variant curation
  • Interoperable reporting

One pipeline, sample to report.

Six deterministic stages

  1. 01

    Sample intake

    Barcoded accessioning with chain-of-custody and consent metadata captured at source.

  2. 02

    Library preparation

    Automated, target-agnostic prep so the same workflow serves every panel.

  3. 03

    Sequencing

    Commodity short-read sequencing, pooled and multiplexed for cost efficiency.

  4. 04

    Variant calling

    Containerised alignment and joint calling against versioned reference panels.

  5. 05

    Interpretation

    Federated curation applies shared classification rules and known-variant evidence.

  6. 06

    Report

    Clinical-grade report issued through an interoperable, auditable interface.

Applications

  • Newborn screening

    Broad, low-cost coverage of actionable conditions at birth.

  • Carrier screening

    Reproductive risk assessment across recessive conditions.

  • Hereditary cancer

    Germline risk panels with federated variant evidence.

  • Pharmacogenomics

    Drug-response markers routed into the same report.
