ISO 9001
  1. Is blood more accurate than cheek cells when testing for paternity?
    No. Cheek cells collected using the buccal swab included in the collection kit yield results with the same accuracy as blood samples do. The DNA is the same regardless if it is collected from cheek cells or blood; the test results are the same from both blood and buccal swabs.

  2. How do I know that I'm collecting my samples correctly?
    We enclose simple, easy to understand instructions for collecting cheek cells. If you follow the instructions carefully, there is no need for you to be concerned with making mistakes.

  3. Could the buccal swabs be contaminated since cells are collected from the mouth?
    No. The DNA testing is not affected by the presence of bacteria, common foods, tobacco or mother's milk.

  4. Can drugs or alcohol affect the test results?
    No. It is impossible to change your DNA with drugs or alcohol.

  5. Can my results be used in court?
    Many courts require a full "chain of custody" for DNA Paternity Testing, requiring tested parties to have their samples collected by a hospital or laboratory where they can be properly identified, fingerprinted and photographed. With our in-home paternity test, you collect the samples yourself; therefore we cannot verify the origin of the samples. An analysis of this nature is therefore not legal proof of paternity and does not possess legal relevance. Its sole function is personal orientation for the contributing party or parties.

  6. The information I receive with the results, will be easy to understand?
    Yes. You will receive technical information as well as the conclusions, which will be perfectly understandable. You will be told if you are or are not the biological father, mother or brother.

  7. What do "probability of paternity" and "paternity index" mean?
    Both terms are intimately related. We recommend you read the technical information page where you will find a general description of the whole process and which will help you understand the following explanation:

    The paternity index is a statistical parameter called likelihood ratio. It compares the likelihood that the alleged father could have produced a child with this genotype by mating with the mother with the likelihood that another (randomly chosen) man could have done so.

    The paternity index is determined strictly from the genetic evidence. Genetic evidence is combined with social evidence (the prior probability of paternity) using Bayes' Theorem of Conditional Probability to calculate the Probability of Paternity. Laboratories typically remain neutral in the assessment of the prior probability by using the value 0.5. By using this value, we assume the alleged father and a randomly chosen untested man have an equal likelihood of fathering the child before any testing is carried out. Using this value, we simply divide the paternity index by one plus the paternity index to obtain the Probability of Paternity. For example, if the Combined Paternity index were 1.000, the Probability of Paternity would be 99.9%.

    It's accepted internationally that if the paternity index is over 400 or the probability of paternity is over 99.75 %, the biological paternity is accepted.

    At ADF TecnoGen we analyse 15 genetic markers, this lets us reach a probability of paternity of over 99.999 %, when the mother is tested, and over 99.9 % when only the alleged father and child are tested. These probabilities let us guarantee an absolute security on our results. In any case, our results are absolutely decisive.

  8. What if the two possible fathers are related?
    Related individuals share more of their genetic code than unrelated individuals and we would need to perform enough testing to exclude one of them. When there are related possible fathers, not testing all parties could result in falsely implicating the alleged father. Both alleged fathers should be tested at the same time, if possible, so that one can be excluded. If only one alleged father is available we recommend you don't request the paternity test to avoid erroneous results.

  9. What if I want to test more than one child or alleged parent?
    Provided that we are testing everyone at the same time, we would only charge US$ 200 (200 euros) for each additional tested party.

  10. Can you send a kit to me discreetly?
    Yes, we can. The kit will be sent to the address you request in a standard size envelope with no markings as to the contents of the package.

  11. Does the mother need to be tested to achieve an accurate result?
    No, DNA testing is so powerful that the mother does not have to participate in the test.

  12. Are the test results and samples confidential?
    Yes. All information and all results are kept strictly confidential. Results are provided only to those adult persons who were tested. Personal information and results are absolutely confidential and never given over the telephone or fax.
