Improving interchangeability of reference materials and quality controls for laboratory tests

New Approaches for Evaluating the Interchangeability of Reference Materials and Quality Controls (COMET-MPL)

Observational University Hospital, Montpellier · NCT07173114

This project tests whether specially made reference materials and quality controls behave like real patient samples on automated lab machines for adults, including people taking certain immunosuppressant medicines.

What this trial studies

COMET-MPL examines the commutability and interchangeability of certified reference materials (CRMs) and external quality controls (EQA) when prepared as multiparametric materials for use on high-throughput automated analyzers. The project compares the performance of these materials to native patient samples across routine clinical laboratory platforms, including a general adult panel and a panel of adults receiving immunosuppressive drugs (cyclosporine, tacrolimus, everolimus, sirolimus). Methods include producing single-parameter commutable preparations, running them on multiple automated systems, and analyzing matrix effects and traceability to reference measurement procedures. The goal is to optimize manufacturing processes so controls and calibrators can reliably support standardized, traceable lab results that meet EU regulatory requirements.

Who should consider this trial

Good fit: Adults aged 18 and over, including a subgroup of adults taking immunosuppressive medications such as cyclosporine, tacrolimus, everolimus, or sirolimus, are the intended participants.

Not a fit: People under 18, legally protected individuals or those unable to give informed consent, and individuals not affiliated with a social security system are not eligible and would not directly benefit from participation.

Why it matters

Potential benefit: If successful, this work could make lab test results more accurate and comparable across machines and laboratories and help manufacturers meet EU traceability rules.

How similar studies have performed: Previous research has shown commutability can be achieved for some analytes and platforms, but many routine parameters remain without suitable reference materials, so this project builds on partial prior successes.
