Is Your Specimen Transport System M40-A2 Compliant? Here’s Why It Matters
We’ll be at ESCMID Global 2025, discussing why M40-A2 compliance is critical when selecting specimen collection and transport systems. Accurate diagnostics start with high-quality specimens, and the right transport system can mean the difference between reliable results and compromised patient care.

The Clinical and Laboratory Standards Institute (CLSI) M40-A2 standard sets rigorous quality control criteria to ensure microbiological transport devices preserve specimen integrity. Despite its importance, M40-A2 compliance is often overlooked. If you're involved in specimen collection, transport, or diagnostics, understanding this standard is essential.

4 Key Reasons Why M40-A2 Compliance Matters

1. Preserving Specimen Integrity – Ensures microorganism viability for accurate lab results. 
2. Reducing Diagnostic Risks – Minimises false negatives, misdiagnoses, and treatment delays. 
3. Standardisation & Reliability – Ensures reproducible results and regulatory confidence. 
4. Regulatory Assurance – Aligns with recognised standards for credibility and compliance.

Why This Matters for You
Specimen transport isn’t just about moving samples—it’s about preserving diagnostic accuracy. Non-compliant transport systems can lead to specimen degradation, false results, and wasted resources. M40-A2-compliant systems, such as MWE’s SIGMA TRANSWAB® and SIGMA Liquid Range, are rigorously validated to maintain microorganism viability over time and temperature variations.

Regulatory bodies, including the FDA, recognise M40-A2 as a benchmark for microbiological transport. Choosing a compliant system streamlines validation, enhances lab efficiency, and upholds the highest standards in patient care.
