IVDR · Performance · Evidence

Eclevar delivers this as part of its full IVD clinical research CRO service under the IVDR (EU) 2017/746, from scientific validity to clinical performance.

IVD clinical evidence, under the IVDR.

The IVDR reclassified most diagnostics and made a Performance Evaluation Report mandatory. Understand the three pillars of performance and the evidence a Notified Body now expects.

The framework

Three pillars of performance.

Under the IVDR 2017/746, clinical evidence for a diagnostic is built on three interlocking pillars, all captured in the Performance Evaluation Report (PER).

01

The classification shift

The IVDR replaced the IVDD and moved from a list-based to a risk-based classification (Class A to D). The result: the large majority of diagnostics now require Notified Body involvement, where under the IVDD most were self-certified. That single change reshaped the evidence burden.

02

Scientific validity

The association of the analyte with a clinical condition or physiological state, demonstrated from the literature, expert consensus and, where relevant, proof-of-concept studies. It answers: is measuring this analyte meaningful at all?

03

Analytical performance

The ability of the device to correctly detect or measure the analyte: sensitivity, specificity, accuracy, precision, limits of detection and quantification, and interference. It answers: does the assay measure what it claims, reliably?

04

Clinical performance & the PER

The ability of the device to yield results correlated with the clinical condition, expressed through diagnostic sensitivity and specificity and predictive values. All three pillars are drawn together in the Performance Evaluation Report, updated across the device lifetime through post-market performance follow-up (PMPF).

What the PER must show

  • Scientific validity of the analyte-condition link
  • Analytical performance against defined acceptance criteria
  • Clinical performance with diagnostic sensitivity and specificity
  • A PMPF plan to maintain the evidence

Questions we hear first

IVD clinical evidence, answered.

What are the three pillars of IVD performance under the IVDR?
Scientific validity (the analyte is meaningfully associated with a clinical condition), analytical performance (the assay correctly detects or measures the analyte), and clinical performance (results correlate with the clinical condition). All three are captured in the Performance Evaluation Report.
Did the IVDR change diagnostic classification?
Yes. The IVDR 2017/746 replaced the list-based IVDD approach with a risk-based classification from Class A to D, meaning the large majority of diagnostics now require Notified Body involvement rather than self-certification.
What is the Performance Evaluation Report (PER)?
The PER is the mandatory document that draws together scientific validity, analytical performance and clinical performance for an IVD, and is updated across the device lifetime through post-market performance follow-up.
Is post-market follow-up required for IVDs?
Yes. Post-Market Performance Follow-up (PMPF) is required to keep the performance evidence current, analogous to PMCF for medical devices under the MDR.
