DNA ClinicsSample Collection Kit for Mother, Child & FatherAdditional Laboratory Fee Required £99Results in just 3 daysAbout this DNA kitThis DNA paternity test is for 1 mother, 1 father and 1 child. The results from the test can only be used for personal information only.If you require a DNA test for legal purposes, you must make an appointment at a DNA Clinic.If you require extra mouth swabs for additional test participants please call 0800 988 7107.How does the Paternity test work?During a DNA Paternity test, different genetic locations are analysed along the DNA molecule.A person possesses two (of many possible) alleles at each location. The alleles are identified by a number. These are inherited from the parents at conception. One comes from the mother and one from the father.Therefore, when the DNA profiles of biological parents are laid out together, one of the child's alleles (numbers) will match up with a number from the mother's sample and the other should match up with an allele from the father's sample.If these alleles match at all locations analysed, a person is included as the biological father of the child because it proves they have passed these genetic markers to the child at conception.Inconsistencies (locations where there is NO match) will exclude a person as a biological father. This is based on the fact that it is only possible to pass on to your offspring the alleles which you possess in your own DNA profile.
