Performance studies using in-vitro diagnostics
- WMO
Performance studies using in-vitro diagnostics are subject to specific rules for submission, assessment and conduct. These rules are outlined in the EU In Vitro Diagnostics Regulation (EU No. 217/745, IVDR), which has been in effect since 26 May 2022.
What is an IVD?
The IVDR defines an in-vitro diagnostic medical device (IVD) as:
“Any medical device that is a reagent, a reactive product, a calibrator, a control material, a kit, an instrument, an apparatus, a device, software, or a system, whether used individually or in combination, and intended by the manufacturer to be used for the in-vitro examination of specimens derived from the human body, including donor blood and tissue, solely or principally for the purpose of providing information on one or more of the following:
- a physiological or pathological process or condition;
- congenital physical or mental impairments;
- the predisposition to a medical condition or a disease;
- determining the safety and compatibility with potential recipients;
- predicting the response or reactions to treatment;
- determining or monitoring therapeutic measures.
Specimen receptacles are also considered medical devices for in-vitro diagnostics.”
For more information, see the MDCG guidance document.
Categories of IVD performance studies
A performance study is “a study conducted to determine or confirm the analytical or clinical performance of a device”. Analytical performance refers to the ability of an IVD to accurately detect or measure a specific analyte. Clinical performance refers to the ability to provide clinically relevant results.
The IVDR distinguishes different types of performance studies, each with specific requirements and procedures:
Performance studies involving risks to subjects (IVDR Article 58.1 and Article (70.2);
- in which the surgically invasive sampling is carried out solely for the purpose of the performance study; or
- which is an interventional clinical performance study in which the test results may influence patient care decisions and/or be used to guide treatment; or
- in which the conduct of the study involves additional invasive procedures or other risks to the subjects of the studies.
- Performance studies with companion diagnostics (CDx) (IVDR Article 58.2);
- Post-market performance follow-up (PMPF) studies with additional invasive and/or burdensome procedures (IVDR article 70.1);
- Performance studies without risks to subjects (IVDR article 57).
Consult the CCMO website for more information on these categories and a flowchart to determine which framework applies to your performance study.
Development of diagnostic laboratory tests in Amsterdam UMC
Under the IVDR, diagnostic laboratories are required to add a justification statement to the validation report. In addition, they must prepare and publish a statement on the use of in-house IVDs for users. Please consult Amsterdam UMC's general topic page on IVDs to learn more about the necessary steps.
