Discover our testing services for genetically modified (GM) foods. Our validated method ensures accurate results, supporting food safety and certification for local farmers, manufacturers, and exporters. Genetically Modified and Other Food Testing Definition Genetically modified (GM) foods are foods derived from organisms whose genetic material (DNA) has been modified through the introduction of a gene from a different organism. Currently available GM foods stem mostly from plants. What we do We use a PCR method to identify the most common genetic elements that are generally found in GM crops. The test is very sensitive and able to detect 0.1% GM content. In addition to the common genetic elements, on request, we also offer to detect other genetic elements that are assumed to have been integrated into the plants during the GM procedure. Our test can be applied to crops such as corn, soy, canola, and potato as well as processed food items such as tea, desiccated coconut, bakery & confectionery items, breakfast cereals & snacks, food additives, and others. Validation of method The test method has been validated according to the guidelines given by the European Commission Joint Research Centre for food samples and uses positive (European Certified reference materials) and negative control samples in order to assure the best qualitative results. Who we help Our testing facility has been utilised by the Food Control Administration Unit, Ministry of Health, Sri Lanka for the screening of imported seeds and food products as well as local farmers, manufactures and exporters to certify their products are free from GM food materials.

Meet Samudi Mohotti, Genetech’s Senior Scientist leading parentage testing, with over 3,000 DNA reports for Sri Lanka’s judiciary. Samudi Mohotti Senior Scientist Samudi Mohotti commenced her professional career at Genetech as a Scientific Officer at the division of parentage testing in 2004. In subsequent years, she was promoted to the post of Senior Scientist and currently oversees the entire process of parentage testing. She is one of the most experienced scientists in the field of DNA typing and has contributed to submit over 3,000 DNA test reports for civil and criminal cases to the Sri Lankan Judiciary. She took part in the development of an allele frequency databases of autosomal STR markers for Sri Lankans ethnicities and co-authored a journal paper in a high-impact journal, Forensic Science International: Genetics. In addition to DNA typing, she is involved in many research projects conducted by Genetech on contract basis to meet the requests from both state and private institutes. She is also a key member of the team which maintains the ISO 15189 quality management system of our laboratory. Samudi obtained her BSc degree in Biological Sciences from the University of Colombo, Sri Lanka and her Master’s degree in Applied Microbiology from the University of Kelaniya, Sri Lanka.

Explore Genetech’s commitment to innovation in biotechnology at our Research Institute (GRI). Pioneering not-for-profit research in Sri Lanka, we welcome diverse minds to shape the future with us. Improvement with innovation Research is the foundation of all our activities. Whilst most of the methodologies we adopt have been researched and developed by us, research is constantly being conducted to optimise and improve our methods. Not-for-profit research We have a not-for-profit research division known as Genetech Research Institute (GRI), which is managed by a Board of Trustees headed by Dhammika Gunasekera. Learn more Active involvement locally and globally GRI is the pioneer not-for-profit private scientific research facility in Sri Lanka, and has in its short history been able to receive research grants from national and international granting bodies. We also actively take part in scientific sessions and symposia locally and internationally. Our welcoming culture Our research facility welcomes independent researchers, undergraduate and graduate research students as we believe diversity is important in creating future-ready solutions using cutting-edge technology.

Explore Genetech’s DNA typing quality control, upholding international standards with expert staff, cutting-edge methods, and stringent error checks. Quality Control DNA typing is a highly specialised procedure which requires knowledge and skill. Furthermore, for DNA typing evidence to be acceptable in a Court of Law, it has to meet certain quality standards, which have been well documented and followed by forensic DNA laboratories worldwide. Accordingly in 2010, we became the first DNA typing laboratory in Sri Lanka to achieve ISO 15189:2007 (now 15189:2012) accreditation from Sri Lanka Accreditation Board (SLAB). We at Genetech are proud to announce that every step of our DNA typing process meets these international standards. At Genetech, our quality standards cover all aspects of DNA typing, including qualified and experienced personnel, the latest equipment, and the best of chemicals and reagents. The entire process is performed to generate error-free results which can be verified by any laboratory in the world. Personnel: Genetech has the most experienced and qualified personnel in the field of DNA typing in Sri Lanka. They have pioneered DNA typing in this country, and have laid the foundation for the application of this technology in Sri Lanka. Equipment: We are a fully equipped organisation which has the ability to perform automated fragment analysis in the exact manner required by the standards. Our equipment are regularly calibrated to ensure error-free functioning. Laboratory management: All aspects of laboratory management and documentation are performed to meet the ISO 15189 standards. Aspects of confidentiality, security and independence have been diligently maintained. Technical quality: The type of DNA testing done by us is the latest, most accepted method known as Polymerase Chain Reaction (PCR) based analysis of Short Tandem Repeats (STRs). This method is presently accepted by the forensic community as the method of choice because of its sensitivity, accuracy, rapidity and cost effectiveness. The type of genetic test: STR loci (genetic locations) which are tested by us are those that are well-studied and regularly used by the forensic community. These include loci found on autosomes, and X and Y chromosomes. The STR loci tested by us are among the most accepted, internationally. These STR loci have also been tested for their suitability to be used for the Sri Lankan population, and they have been proven to be statistically suitable. There is also an established Sri Lankan population database for these loci which enables such DNA evidence to be presented to a Court of Law. In addition to STR testing, we also conduct mitochondrial DNA analysis as required, to assist tracing of maternal lineages. Error minimisation: In order to minimise the possibility of error, we will maintain standards of validation and verification. The analysis of casework samples will be done alongside internationally used standard human DNA, and the results of the casework analysis will be subject to comparison with these DNA standards. Negative controls will be run at every step of the analysis procedure in order to ensure that no cross-contamination of DNA has occurred. Reporting: Once DNA typing results are generated, they are stored in both a graphic format as well as in a numerical format. An individual's DNA profile can be submitted to a Court of Law in both formats. Our scientists can provide statistical interpretation of the results and express the accuracy of the test by statistical means, using data generated from the Sri Lankan human population databases. In order to be valid in a Court of Law, DNA evidence must be supported by statistical data. This data is obtained only by establishing a population database for the population group that is being tested. Therefore, only Sri Lankan population data can be used for such analyses.
