Bird DNA Sexing Why DNA Sexing Matters Accurate sex determination is essential for breeding, conservation, and pet ownership, particularly in monomorphic species where males and females appear identical. Even in species with visible differences between males and females, gender traits often develop only in adulthood. Knowing a bird’s sex is crucial for forming proper breeding pairs, helping breeders, and providing important information to pet owners and buyers before selling birds. Sample Collection Process To submit a sample for Bird DNA Sexing, 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 (such as the bird’s name, ring number, or cage number). 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 We provide 99.9% accurate molecular sexing for a wide range of bird species. Our method is non-invasive, typically using feathers, though blood and other tissues are also accepted. The process is quick, efficient, and cost-effective, delivering reliable results for bird owners, breeders, and conservationists. Contact us View Price List Sample Acceptance Sheet

DNA Typing Our passion to improve We pioneered the use of DNA typing for human identification for forensic casework and analysis of family relationships including parentage testing. We are a major supplier of this technology to the medico-legal community and the judicial system in Sri Lanka. Our reputation for integrity and reliability has made us the main provider of forensic DNA testing in the country. Over 4000 cases of disputed parentage and another 4000 criminal cases have had the advantage of DNA evidence through Genetech. What is DNA typing? DNA typing is a method of identifying individuals from the differences in their DNA. It is used for forensic casework as well as for determining familial relationships between individuals including paternity, maternity and siblingship. Advantages of DNA typing The science of DNA typing relies on technology that allows an individual's DNA to be examined and analysed. A person's DNA is unique: no two individuals (with the exception of identical twins) have the same DNA. Every cell in a person's body has the same DNA. Hence, DNA taken from any part of the body from the same individual will always be the same. DNA typing can be performed from many types of biological specimens including blood, saliva, sperm cells, muscle, teeth and bones. Thus, a person's DNA can be typed from very little tissue or body fluid. DNA typing is used for two major purposes: Identification of individuals from biological samples: This is mainly done in forensic casework, where it is possible to determine the identity of a criminal by typing the DNA left behind at the scene of the crime. Determination of familial relationships: This includes paternity testing, maternity testing, sibling testing, grand-parent testing, and even the identification of mutilated bodies. DNA typing is the best method of identifying individuals and determining familial relationships due to many reasons. It is extremely sensitive: with even a very small amount of tissue, the test can be performed successfully. It is also very accurate: it can give a test result with a very high degree of certainty. It is very reliable: the likelihood of obtaining a false result can be minimised, and the likelihood of making an error in the conclusion can be calculated. How does DNA typing work? In the DNA typing process, a DNA banding pattern or profile of an individual is first obtained from a tissue sample. The DNA profile is observed in the form of a set of DNA bands known as alleles. Each person has a maximum of two specific alleles for a given genetic location. This DNA profile is compared with the profile obtained from a sample taken from the scene of a crime. If the alleles in the two profiles match, then it can be said that the sample taken from the scene of the crime is from the individual that was tested. DNA typing services Child custody and maintenance: In cases where one parent is claiming the custody and maintenance of a child and the other parent is refusing to accept parentage. Proof of adultery: Especially in divorce cases where the paternity of the child is suspect, and the wife is being accused of adultery, DNA typing can be used to determine whether the husband is the father of the child. View all Cost We are happy to announce that after much research and optimisation, we have streamlined our DNA typing methods, and we are therefore able to provide DNA typing services at a reasonable cost. We perform the same DNA typing tests which are used by internationally recognised laboratories, and maintain the same standards of quality so that the conclusions made by us can be verified by any accredited forensic DNA typing laboratory in the world. Contact us View Price List 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). Read more Accuracy of evidence DNA testing is the most accurate and reliable means of identity verification and parentage testing. The degree of accuracy of the test will depend on the genetic diversity of the Sri Lankan population as well as the number of genetic locations (STR loci) which are tested. There is no mandatory number of STR loci required for a test, but the testing of nine STR loci or more is generally considered to be sufficiently accurate. We test up to 15 STR loci. Read more Ethical Guidelines DNA typing is performed ethically only with the informed consent of the individual whose DNA is being typed. The persons concerned will be informed about the consequences of the test. Where such consent cannot be given such as in the case of minors, the consent of the guardian has to be obtained. We will not undertake samples for parentage testing without written consent from all living parties who will be tested.

Animal Testing What is Parvovirus and why is early diagnosis essential? Canine Parvovirus (CPV) is a highly contagious pathogen primarily affecting dogs. This virus can also infect other mammals including cats. If untreated, the risk of death may be high. Thus, a rapid and early diagnosis could save their lives. ​ Detection of the virus can help you select an appropriate treatment regimen for your animals, prevent the spread of the virus and save them from secondary infections. Why we recommend a PCR test over an ELISA test The sensitivity of an ELISA test depends on the Ag/Ab concentration and the availability. Thus, it could lead to false positive or negative results. In contrast, our PCR (Polymerase Chain Reaction) test detects the viral genome and produces no false positive or negative results. This is because it is dependent on the availability of the virus but not its products or Abs. The positive result of an ELISA test can be caused by organisms other than the target. On the other hand, our PCR test detects genetic sequences unique to the target pathogen. Therefore, its specificity is much higher than an ELISA test. The accuracy of the ELISA test varies, and it depends on the Ag/Ab availability. Our PCR test offers a consistent accuracy of 99%. What is tick fever and why may early detection be crucial? Tick fever is a common canine disease in Sri Lanka which is caused through the bite of an infected tick carrying an insidious and deadly organism. Scientifically, it is known as Canine Ehrlichiosis and Canine Babesiosis. ​ Early detection may prevent the dog from experiencing severe anemic conditions caused by the disease due to the highly pathogenic nature of it. Furthermore, the specific detection will help choose a suitable treatment regimen for your dog. Why microscopy and antibody tests are not ideal Some stages of the parasite life cycle cannot be observed through the microscope. Therefore, the probability of obtaining false results is high. It takes several days to develop antibodies against a certain infection in the body. Hence, it is difficult to diagnose the infection early. Antibodies may be present in the body even after the disease is cured. Thus, if the test is done after the infection is cured, the result may be false positive. What we offer We are the first firm to provide a PCR based animal disease testing service in Sri Lanka. We offer tests which detect Canine Parvovirus, Canine Distemper, Canine Babesiosis and Canine Ehrlichiosis. In addition to animal disease testing, we provide a cattle parentage testing service through the use of DNA typing. Contact us View price list

Ethical Guidelines DNA typing is performed ethically only with the informed consent of the individual whose DNA is being typed. The persons concerned will be informed about the consequences of the test. Where such consent cannot be given such as in the case of minors, the consent of the guardian has to be obtained. We will not undertake samples for parentage testing without written consent from all living parties who will be tested. In the instance of criminal casework, we adhere to provisions in the Law, with respect to taking samples from suspects, victims and other living individuals involved in the case. Strict confidentiality will be maintained at all times with respect to individuals being tested. The results of DNA typing tests and the conclusions drawn from them will be divulged only to the persons being tested, and Courts of Law which order such tests. The test result will be given in a numerical format; a Scientist from Genetech will interpret the results, drawing a clear, unambiguous conclusion, and express it in simple terms. DNA typing is performed by analysing non-coding regions of an individual's DNA. It does not give the analyst any information about the ethnicity, race, social background, physical or mental make up of that person. Therefore, no other genetic information will be retrieved from an individual's DNA.

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.
