Parentage Testing

Parentage testing uses samples from parents and children to determine the authenticity of their genetic relationship. Relationships can also be determined if either of the parents is unavailable for testing (E.g. deceased, overseas, reluctant to participate, etc.). Our legally binding DNA test apply to all of application for certificate of birth, child custody, claim of inheritance and other identity proofs etc….

  • Parentage testing can be used to confirm whether a migrant claiming right of abode from another relative is indeed related. It helps in claiming inheritance and child maintenance payments. parentage testing is widely used in criminal and forensic investigations, missing person identification and deceased persons identification.

    Legal Use Parentage Test (ISO)
    Our DNA parentage test reports are acceptable for use in court. The sample collection and analysis process should be supervised and fully documented

    Anonymous Use Parentage Test (Non-ISO)
    Donors simply collect their own samples using the GeneTek DNA parentage testing Sample Collection Kit and return them to us for analysis. Despites picking up the test report in person, results can be checked by phone call, email or mailed to donors after analysis is completed. The results of anonymous tests cannot be used in court as there is no way to confirm that the tested sample was provided by the party involved in the legal case.

    2. How long does it take to get your test result?
    Our turnaround time is 3- 5 working days from sample pickup date.

    3. How will I receive my parentage test result?
    Official report will be sent by mail or registered mail to the address provided with confidentially manner. To maintain the highest confidentiality, we can verbal the results to you by phone with identity checking.

    4. How do I interpret the Paternity Test report?
    The alleged father/mother is either "excluded" or is "not excluded" as the biological father or mother. Each of the 15 genetic loci is analyzed separately to calculate a paternity/maternity index PIs, and all individual indexes are combined to calculate a "Combined Paternity Index (CPI)" or “Combined Maternity Index (CMI)”, which refers to product of all of the individual PIs when the genetic system employed are inherited independently.
    The Paternity/Maternity Index is a number that represents the likelihood of Paternity/Maternity. The number calculated based on how common the genetic information found in your test result is within your race population. The likelihood of paternity/maternity can result in a 99.99% or even higher in the case of a true match.

    5. Can our parentage test report(Legal Use) be used in court?
    Yes, if you order a Legally Binding Test. As parentage test report for legal use require additional proof of identity and chain of custody. With our parentage testing service, our scientists and the donor provide complete documentation of the chain of custody to ensure that the sample given by the donor can be used as evidence in court. We maintain careful records on every sample processed. Results from HKLife are admissible in a court of law.

    6. Are the results confidential?
    Your results will be held in strictest confidence and released only to you. Furthermore, the information obtained from testing the 15 genetic loci relate only to identity, and do not reveal any additional information of medical relevance.

    7. How accurate are the DNA paternity test results?
    DNA testing is the most accurate method available for determining paternity. According to person’ genetic at specific location, it enable to trace the pattern of inheritance for separate regions of the genetic material (chromosomes). From this information a probability of paternity can be calculated. This number can reach 99.999% in some cases. The percentage of random men of the same race that can be excluded as the biological father according to AABB Standards (1999), 2 or more mismatches at different loci are required for exclusion in DNA testing for parentage.

    8. How does a DNA parentage test work?
    A child inherits DNA from the mother's egg (23 chromosomes) and the father's sperm (also 23 chromosomes). Each parent contributes half of the child's DNA. The child (and every person) has 23 pairs of chromosomes. For each location in a chromosome pair there is a specific genetic repeats (called STR). A DNA parentage test works by identifying the STR for multiple loci in the mother, child, and father. If the mother and father are the biological parents of the child, the two STR at each locus in the child's chromosomes must have been inherited from each parent. Determining paternity and maternity is possible from these STR.

    9. Is the legal DNA test different from the informational DNA test?
    No. The DNA testing is identical. The only difference is that legal DNA tests require an unrelated, third party witness to oversee sample collection, proof of identity, and special chain of custody procedures. The basic Paternity Test Kit therefore is not legally binding. It is intended as a discrete and private way whereby families can resolve questions without involving outside parties.

    10. What is a buccal swab and is it as accurate as blood?
    A buccal swab resembles cotton swab. It is used to collect cheek cells by rubbing the inside of the cheeks but not only saliva. It is as accurate as blood.

    11. How old does a child need to be to perform a DNA test?
    A newborn infant can be tested. Taking a sample with a buccal swab is painless.

    12. What happens to my DNA samples once the test is complete?
    HKLife shall dispose all samples as clinical waste procedure after the test report has been delivered.
