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 trailblazing molecular diagnostics in Sri Lanka, accredited with ISO 15189. Specializing in PCR-based detection of viral, bacterial, and other infectious diseases, genetic disorders, and cancer markers since 2002. Molecular Diagnostics Did you know? We pioneered the use of molecular diagnostics in Sri Lanka. This field, which was almost unknown to the medical fraternity in Sri Lanka is now widely used in delivering high quality patient management. Molecular diagnostics is now an accepted and even essential part of the health care system since it was introduced to Sri Lanka by us in 2002. How we strengthened our clients' trust In order to standardise our tests and strengthen our clients' trust, We have applied for and obtained ISO 15189 accreditation. Thus, our tests including those related to molecular disease diagnostics are excellent in all aspects. The importance of nucleic acids Infectious diseases are caused by a wide variety of organisms, ranging from multi-cellular parasites and fungi to uni-cellular bacteria to non-cellular viruses. These organisms cover a wide range of phyla, and have extremely diverse ways of infecting human beings. In spite of these differences, they all possess nucleic acids (DNA or RNA molecules), their hereditary material. This DNA or RNA forms the basis of their individuality, and because it is the basis of diversity, it is possible to identify these organisms from their DNA or RNA. What we offer with PCR technology Unlike other diagnostic methods, which rely on microscopy, culture, biochemical characteristics and indirect antibody detection, molecular diagnostics seeks evidence of a disease at the very basic causative level by detecting the nucleic acids based on PCR (Polymerase Chain Reaction) technology. This technology is also used to detect changes or mutations in our DNA, which can cause disease conditions known as genetic disorders. While some of these genetic disorders are passed from generation to generation, some happen spontaneously. Genetech offers DNA-based testing services for a wide variety of such genetic disorders and cancer markers. Contact us View Price List and Sample Collection Guide

Learn about Psittacine Beak and Feather Disease (PBFD) and how Genetech offers a PCR-based test for early detection. Submit feather or blood samples for reliable PBFD screening. Psittacine Beak and Feather Disease (PBFD) What is PBFD? Psittacine Beak and Feather Disease (PBFD) is a viral infection caused by a circovirus, primarily affecting parrots, cockatoos, and other psittacine birds. This virus leads to feather abnormalities and changes in beak formation. PBFD spreads through feather dust, faeces, and contaminated surfaces. The infection can be deadly in young birds and, in some cases, adult birds, as they may carry the virus without showing symptoms. As there is no specific treatment for PBFD, early detection is crucial for effective management through stringent quarantine and hygiene practices. Sample Collection Process To submit a sample for PBFD screening, follow these steps: Pluck 5-6 feathers from the bird’s chest area. Place the feathers in an envelope or a plastic zip-lock bag. Label the envelope or zip-lock bag with your bird ID (name, ring number, cage number, or other preferred identification). Complete the sample acceptance form and submit it along with the samples (available at the Genetech Reception or downloadable here ). You can submit the samples in person or by courier to: Genetech 54 Kitulwatte Road, Colombo 00800 For mail or courier submissions, place the sealed samples and completed sample acceptance form inside an envelope. We will notify you once the samples have been received. What we offer At Genetech, we offer a PCR-based screening test for PBFD using feather or blood samples.
