Due to organizational changes in our laboratory, we are currently no longer accepting new orders for DNA testing or providing new sample collection kits. All previously ordered tests for which samples are received by our laboratory no later than 30 November 2026 will be processed as usual.
Thank you for your understanding.

If you have any questions please call +421 908 29 77 26 during working hours.

 

Paternity testing based on DNA analysis has become a routine procedure in providing evidence for the relationship between the biological father and child as well as in case of eliminating any doubt of the child’s father or mother with respect to paternity of that child. DNA paternity testing can confirm or rule out biological relationship practically with a 100 % certainty. Postnatal paternity testing is in our laboratory accredited according to the ISO/IEC 17025: 2017 Standard.

Analysis process

Standardised sets of chemical substances are applied in laboratory sample analysis, together with laboratory devices equipped with software designed to analyse specific genetic markers passed on to each individual from his or her biological parents in the 1:1 ratio. Each individual carries in their DNA one version of a genetic marker (allele) from their mother and one from their father. Based on identification of these markers, we can, by direct comparison, find out whether the tested father is or is not the child’s biological father. Simultaneously, we can calculate the paternal probability of the tested man in relation to the child. Currently applied methods allow accuracy exceeding 99.9 % in case of proving paternity (this value is labelled as practically proving paternity) and as much as 100 % in case of eliminating the probability of paternity.

Application of paternity testing is not strictly reserved for suspicious men who feel to be cheated on – in practice, we often meet with cases when this type of testing was applied in relation to entitlement to heritage, if a woman became pregnant at a time of changing life partners and she wished to make sure, which of them is the biological father, but also when biological samples need to be identified, e.g. in case of a kidnapping, after disasters or to identify bodies buried is mass graves.

Types of tests

  1. Prenatal paternity testing – this test is conducted before the child is actually born. Sampling for this sort of tests can be carried out after completion of the 10th week of pregnancy (it is necessary to get an appointment in advance). In a small part of the samples (up to 10 %) the result cannot be obtained and the test needs to be repeated due to low level of foetal DNA in the blood of the pregnant woman. If this is the case, the repeated blood sample collection needs to be carried out not sooner than 2 weeks following the first sampling. No fee is charged for this repeated test.
    1. Universal paternity testing
      Is designed for pregnant women with either male or female fetus, therefore the sex of the fetus does not need to be known in advance. The test can not differentiate between biologically related potential fathers (e.g. brothers, father and son, uncle and nephew  etc.). Standard procedure requires a sample from a pregnant woman and a sample from the potential biological father of the fetus.
  2. Postnatal paternity testing
    These are tests conducted after the child is born. Sample is collected with sampling tampons and is totally painless.

    1. Anonymous paternity testing
      Collections are carried out by the client with the collection sticks sent by us. Standard procedure analyses the 1st sample from the pregnant woman, 1st sample from the child and 1st sample from the potential biological father. However, sample from the mother is not essential to conduct the test successfully.
    2. Forensic paternity testing
      Collection is carried out under supervision of a legal forensic expert, who unambiguously verifies and validates the authenticity and also guarantees the maximum level of confidentiality. This type of testing can serve as evidence in legal proceedings. Standard procedure analyses the 1st sample from the pregnant woman, 1st sample from the child and 1st sample from the potential biological father.
