Frequently Asked Questions
The following questions are those most frequently asked by clients. If your questions are not answered by this information, please feel free to contact us at contact@catdna.org.
Q: Can I test my cat to find out what breed it is or prove that it is purebred?
A: No, There is not a definitive DNA test available for accurately determining breed make-up, breed purity, or "bloodline" of an individual.
Q: For parentage testing, why should I send the mother's sample if I already know she is the mom?
A: Having the mother's DNA makes a parentage evaluation much more definitive. It is important to identify the mother's half of the offspring's DNA profile first. Having eliminated that as potentially being contributed by a sire, one can more effective identify the true contribution of the biological sire.
Q: Can parentage testing be done without the mother's sample?
A: Yes, when the mother is not available, a parentage verification can be done; however, extended testing using additional DNA markers is needed to compensate for the mother's absence.
Q: What kind of sample is needed?
A: The preferred method for all testing is the buccal (cheek) swab, but we are capable of testing on a variety of sample types.
Q: At what age can testing be done?
A: DNA testing can be done on cats of any age.
Q: How long does it take to get results?
A: From the time samples are received at our laboratory, results are completed within 10 business days.
Q: How do I order DNA testing?
A: We will gladly answer your questions and send you the free DNA sample collection kit. Simply email us at contact@CatDNA.org or order from the testing pages online at www.CatDNA.org/dna-tests.
Q: How is DNA testing performed?
A: The technology we use most often is polymerase chain reaction (PCR) testing. First we isolate pure DNA from the specimen (a cheek swab, blood, or hair sample) by removing all the proteins and other things that can be found within a cell.
The DNA is then placed into a thermocycler along with fluorescent primers for specific "loci" or locations on the DNA that enable the system to locate specific fragments of DNA. The thermocycler is set to cycle through a certain number of temperature cycles. Throughout the cycles, the primer finds specific areas within the DNA that are repeated and amplifies those areas. After the DNA has been amplified, it is place in an ABI Prism Genetic Analyzer for capillary electrophoresis. In this process, the DNA loci are mapped and data on each is collected. This results in a comprehensive "profile" of each individual. These individual profiles are then reviewed by a trained, experienced Ph.D.
Q: How is DDC different?
A. DDC is the world's largest and most experienced private DNA testing laboratory. Its mission is to provide quality testing and legendary service for all who seek DNA testing services.
DDC's ultramodern laboratory complex, equipped with state-of-the-art laboratory technology for performing DNA parentage testing, occupies over 128,000 square feet. DDC highly developed testing methods are the industry's standard for accurate, legally defensible human DNA testing, performing 3 out every 4 private human paternity cases in the U.S. DDC has performed DNA testing for clients in all 50 states and over 168 countries.
DDC's laboratory directors and professional staff have a combined experience of over 100 years in DNA technology, paternity testing, forensics, and veterinary diagnostics. The laboratory directors all hold doctorate degrees in DNA technology and are licensed for performing DNA testing.
DDC's efforts to provide quality DNA testing services are nationally and internationally recognized through a number of accreditations. DDC has achieved perfect ratings in its past 10 consecutive inspections, including those by AABB and the College of American Pathologists (CAP). DDC is also accredited by the FQS-I to meet the standards of ISO 17025 and the DNA Advisory Board (DAB).
