QCMD – External Quality Assessment for Molecular Diagnostics

QCMD – Quality Control for Molecular Diagnostics is a leading international External Quality Assessment (EQA) and Proficiency Testing (PT) organisation dedicated to improving the quality and reliability of molecular diagnostic testing. Specialising in infectious disease diagnostics, QCMD supports laboratories worldwide by providing independent assessment programmes designed to evaluate laboratory performance and ensure confidence in molecular testing results.

Operating in more than 120 countries and supporting thousands of laboratories globally, QCMD offers a comprehensive portfolio of EQA schemes covering viral, bacterial, fungal and parasitic pathogens, as well as syndromic and emerging infectious diseases. The programmes are designed to challenge laboratory assays under routine testing conditions, helping laboratories identify potential issues, improve performance and maintain high standards of quality assurance.

QCMD schemes support regulatory and accreditation requirements including ISO 15189 and are accredited to ISO 17043 standards. Through detailed performance reports, peer group comparisons and educational feedback, laboratories gain valuable insight into assay sensitivity, specificity and overall testing accuracy.

Trusted by clinical laboratories, public health organisations and diagnostic manufacturers worldwide, QCMD plays a key role in advancing quality, standardisation and confidence in molecular infectious disease diagnostics.
