• What is the paternity test?

    It is a genetic test (DNA) performed to determine whether the man is the biological father of the child. If the DNA test shows that the alleged father is not the biological father of the child, we are dealing with negation (exclusion) of fatherhood. If the test shows that the alleged father can not be excluded, we speak of confirmation of fatherhood. In this situation, the probability of paternity is calculated. If it is 99% or more, the man is referred to as the biological father of the child.

  • Are DNA tests accurate?

    Genetic tests are extremely accurate. Nowadays there is no any more precise method of identifying individuals and determining who the real biological father of the child is. Traditional methods, such as systems based on blood groups or comparing the anthropology characteristics, in many cases may be unreliable. Technologies used by Meditest allow for exclusion of paternity with a probability of 100% and its confirmation with a probability greater than 99.99%.

  • How does the DNA test work?

    Meditest uses the latest and the best standardized methodology for DNA testing, based on analysis of 15 so-called microsatellite genetic markers located in different regions of human chromosomes. These markers are known to vary between individuals in  a population. By comparing the DNA profiles of a child, his mother and alleged father, we can precisely determine which markers are derived from the biological father. If the alleged father has not more than 2 of 15 of these genetic markers, his real paternity is excluded. If the alleged father has all the required genetic markers, then with high probability it is considered that he may be the biological father of the child.

    Paternity index (PI) is calculated statistically for each marker of DNA as the probability that the alleged father of the child passed this marker, divided by the chance that a random individual has the same marker as the child. Then, in order to authenticate the probability of paternity is calculated combined paternity index (CPI) - by multiplying the PI value for particular genetic markers. The higher the CPI, the greater the certainty that the alleged father is the biological father of the child. In reliable genetic tests the CPI rates of above 99.9%.

  • Is it possible to perform the test without the participation of mother?

    Yes. Home paternity test with the selfDNA kit can be reliably performed without the need to test maternal DNA, although in a situation of confirmation of paternity the result may be less certain. In rare situations, because of so-called DNA mutations in the child or in the father, test result can be ambiguous. In such situations it may be necessary to include the mother to the test and/or use of an extended panel of molecular markers.

  • Do all persons participating in the test have to provide samples at the same time?

    No, it is not necessary. It is possible to take samples for testing from each individual at different time and place. Samples (appropriately labeled) can be sent to the Meditest laboratory separately.

  • Is it possible to test additional persons (eg, another child) after the initial test was performed (eg father and first child were tested)?

    Yes. At any time, it is possible to take samples for testing of additional persons in different time and place. DNA profile of these additional individuals is compared with previously obtained test results.

  • What is a buccal swab, and how its examination is comparable to a paternity blood test?

    Buccal swab is used to obtain cells from the inner surface (the mucosa) of the cheek. These cells are used as a source of DNA for genetic paternity testing. It is noninvasive, painless, allowing for avoiding blood sampling, feasible and safe even in neonates. Buccal swabs give the same results as blood tests and are now recognized even by the courts. The main advantage of this method is the possibility of self-examination, even at home, using selfDNA kit. This kit Meditest sends by mail.

  • Is it possible to take a buccal swab after a meal and / or alcohol?

    Yes. You only need to rinse your mouth thoroughly. Some remains of food can interfere with the operation of the test.

  • Would age or taking medications affect the test result?

    No. This can not change your DNA.
