Genomics & NGS Testing
Varies by jurisdiction

Diagnostic testing is regulated differently in every jurisdiction. VectorGene supports local validation and accreditation; the regulatory dossier remains owned by the local institution.

Distinguish specialist assessment from population screening.

The intended patient population matters as much as the biomarker. Review the proposed assay’s own evidence and status, and describe how a result would be combined with specialist assessment. Avoid transferring the indication or clearance of a different commercial test to this partner service.

The blood test cleared by FDA in May 2025 was intended to aid assessment of symptomatic adults aged 55 and older in specialised care. FDA explicitly described it as unsuitable for screening or standalone diagnosis. That clearance does not establish the status of the partner service on this page.

Questions for the programme brief

  1. Which assay and population?

    Request the named assay, biomarkers, intended age group, symptom criteria and documentation of its permitted use.

  2. Which clinical pathway?

    Identify the specialist service, additional evaluations and management of indeterminate or conflicting findings.

  3. What supports the claim?

    Review assay-specific evidence, sample handling, analytical performance and how the report communicates limitations.

What to prepare for review
  • Named assay and intended-use documentation
  • Specialist assessment and referral pathway
  • Validation evidence and example report
