DNA (deoxyribonucleic acid) is a molecule that carries our genetic code and is unique to each of us. Almost every cell in the body contains a complete set of DNA that is inherited from our biological parents (half from each parent).
In general, people have unique DNA profiles, except for identical twins, whose DNA profiles are identical. Differences in DNA sequences or patterns are used in DNA parentage and kinship testing. These patterns of repeated DNA sequences are termed short tandem repeats (STRs). At Lancet Laboratories, a higher number of markers are used to ensure greater confidence in the results obtained.
A person gets half of their DNA from their mother and half from their father.
By testing the mother, we can see which half of the DNA she contributed to the child.
Once this is determined, the remaining DNA contribution (other half) is only compared to the alleged father’s DNA.
NB: WITHOUT the mother’s sample, a paternity test can possibly falsely include an alleged father OR can lead to an inconclusive result, with the statistics being too low. For a more in-depth discussion, please see the ‘Motherless Paternities’ leaflet.
Parentage testing is a booked test and takes approx. 45 min at the depot.
Only specially trained and competent staff at approved depots are authorised to collect samples for parentage tests.
Only a government issued ID/passport, driving licence, birth certificate, refugee permit or clinic card will be accepted as proof of identity. An original affidavit may can only be supplied in exceptional circumstances.
Please contact Client Services at 0860 LANCET or email@example.com for details of your nearest approved depot.
All tested parties (or their legal guardians) MUST agree to the test and provide written consent for a sample to be taken and analysed by the Laboratory. If available, the mother of a minor child (<18 years) must provide this consent, unless an affidavit or court order states otherwise.
