IVD Analytical Validation That Accelerates Global Approval

Expert-led analytical performance studies for IVDR, FDA, and CLSI compliance-covering sensitivity, specificity, stability, and APRs. Unlock faster market access with MDx CRO.

Why Analytical Validation Matters

Analytical validation is the foundation for IVD clinical evidence and regulatory approval. Whether launching a new diagnostic assay or transitioning a legacy product to IVDR, robust analytical performance data is essential for demonstrating assay reliability, accuracy, and safety. At MDx CRO, we deliver analytical studies that meet the highest global standards-ensuring your performance claims are supported, submissions succeed, and timelines stay on track.

  • Comprehensive scope: Analytical sensitivity, specificity, accuracy, precision, LoD/LoQ, linearity, and stability studies.
  • Regulatory alignment: IVDR Annex I, FDA 510(k)/PMA, and CLSI guidelines (EP05, EP17, EP25, etc.).
  • ISO 15189-qualified lab partners and a proven track record with Notified Bodies and the FDA.

Frequently Asked Questions

Ask us a Question
  • What is the difference between analytical and clinical validation?

    Analytical validation confirms that an IVD accurately, reliably, and consistently measures the analyte of interest (e.g., sensitivity, specificity, precision). Clinical validation assesses how well the test identifies a clinical condition in the target population. Both are required for IVDR and FDA submissions.

  • Can MDx help with APR creation and IVDR Analytical Performance Reports?

    Yes. We provide full APR development, including statistical analysis, summary writing, and formatting for IVDR and FDA requirements.

  • Do you support CLSI-compliant documentation?

    Absolutely. Our protocols and reports are aligned with CLSI standards (EP05, EP17, EP25, etc.), ensuring global regulatory acceptance.

  • What types of technologies do you support?

    We cover PCR, NGS, immunoassays, IHC, multiplex, lateral flow, SaMD, and more.

  • How quickly can an analytical validation study be completed?

    Timelines depend on assay complexity and sample availability, but most studies are completed in 2–6 months with MDx CRO’s project management.
