GMO testing refers to the use of molecular biology, immunology, and biochemistry methods to detect whether food and its ingredients contain genetically modified components and to assess their safety. This type of testing is crucial for food safety regulation, import trade, consumer rights protection, and corporate compliance.

• Testing Content: Qualitative and quantitative analysis of genetically modified components (e.g., Bt protein gene).
• International Standards: Based on requirements from the European Union (EU), the U.S. FDA, and China's national standards (GB).
• Technical Methods: PCR technology, gene chips, etc.
