Frequently Asked Questions
Ask Us a Question- How does an IVD CRO run ISO 20916 clinical performance studies?
We scope endpoints and study design, develop protocols and eCRFs, qualify sites, monitor conduct, manage data and biostatistics, and compile clinical evidence for the performance evaluation report. Our approach aligns with IVDR Annex XIII/XIV and Notified Body expectations.
- What does an IVD CRO do?
An IVD CRO designs and executes analytical and clinical performance activities, prepares technical documentation, and supports IVDR and FDA submissions. At MDx CRO, we integrate regulatory, biostatistics, site management, and quality to deliver ISO 20916-compliant evidence for CE marking and U.S. approvals.
- Are clinical studies required for EU IVDR compliance?
Not always. Under EU IVDR, clinical performance must be demonstrated through one or more of the following sources:
- Clinical performance studies (Annex XIII & Annex XIV),
- Scientific literature relevant to the device’s intended purpose, or
- Published experience from routine diagnostic use.
Manufacturers must plan this evidence in the Performance Evaluation Plan (PEP) and summarize it in the Clinical Performance Report (CPR) and Performance Evaluation Report (PER). While not all IVDs require a new clinical study, at least one of these sources must be available and sufficient to support the claimed clinical performance.
- Can MDx support LDT-to-IVD transitions?
Yes, we help labs and test developers convert LDTs into compliant IVDs with support on documentation, validation, and market pathway selection.
- How long does CE marking typically take?
Most clients reach CE mark readiness within 6–18 months depending on risk class, data readiness, and notified body availability.
