Genetic Marker Detection (Species Identification & Authenticity Testing)

Verifying Authenticity Through Molecular Science 

In today’s global supply chains, authenticity and traceability are critical across both food and non-food industries. Mislabeling, species substitution, and fraudulent claims can impact regulatory compliance, sustainability goals, and consumer trust. 

At METS Laboratory, our Genetic Marker Detection services provide accurate species identification and authenticity verification using advanced DNA-based molecular techniques. By analyzing genetic markers, we determine the biological origin of samples with high precision, even in processed or complex materials. 

What Are Genetic Markers? 

Genetic markers are unique DNA sequences that act as biological identifiers for each species. These molecular signatures allow precise differentiation between species, even those that are closely related. 

Unlike visual inspection or chemical analysis, DNA-based testing remains reliable even when materials are processed, refined, or physically altered. 

Why Genetic Marker Detection Matters 

Genetic marker analysis supports: 

• Species authentication and verification 
• Prevention of fraud and substitution 
• Regulatory and import/export compliance 
• Protection of consumer trust 
• Support for sustainability and traceability programs 
• Verification of declared material origin 

As global supply chains become more complex, molecular testing provides a reliable scientific foundation for authenticity assessment. 

Food and Biological Applications 

Genetic marker detection is widely used in food testing for species identification, including meat authentication, food fraud detection, and compliance with religious or dietary requirements. It also supports GMO screening, pathogen detection, and waterborne parasite identification, ensuring safety and transparency across the food supply chain. 

Wood Species Identification and Timber Authentication 

Wood and timber products often undergo extensive processing, making traditional identification methods unreliable. Once transformed into veneers, plywood, paper, furniture, or engineered wood, visual characteristics are typically lost. 

Genetic marker detection provides a powerful molecular solution for identifying wood species and verifying timber origin. 

Applications in Wood Testing 

METS Laboratory performs DNA-based wood species identification for: 

• Timber authentication and verification 
• Detection of declared vs. actual wood species 
• Identification of protected or endangered tree species 
• Support for sustainable forestry certification programs 
• Import and export compliance verification 
• Investigation of illegal logging and timber fraud 

This molecular approach enhances transparency and supports responsible sourcing practices across global timber supply chains. 

Next-Generation Sequencing (NGS) for Wood Species Identification 

For highly processed, mixed, or complex wood products, METS Laboratory utilizes NextGeneration Sequencing (NGS) to achieve advanced species resolution. 

NGS enables simultaneous sequencing of millions of DNA fragments, providing deeper genetic insights than conventional methods. This is especially useful for degraded or composite samples where standard PCR-based identification may be limited. 

Key Applications of NGS in Wood Testing 

• Identification of multiple species in mixed timber products 
• Analysis of processed materials (plywood, veneers, engineered wood, paper) 
• Detection of rare, protected, or endangered tree species 
• Complex supply chain verification and traceability studies 
• Advanced forensic investigations of timber origin 

By combining genetic marker analysis with NGS technology, METS Laboratory delivers highresolution molecular insights that strengthen confidence in wood authenticity and sourcing integrity.
