We analyse the DNA from your samples and can determine a possible biological relationship between the test participants.
Those parts of your DNA that we analyse for a paternity or other relationship do not show any trace of possible diseases.
Every cell in our bodies contains the complete set of DNA which determines who we are and what we look like. Accordingly, we could work with samples from all over a persons body, either roots of the hair, dander from fingernails or a comb, saliva from cigarette buds etc. Yet, the German Gene Diagnostics Act strictly restricts the choice to samples of blood or mouth swabs.
During a DNA paternity test we analyse the DNA code sequences, the so-called genetic markers. Related persons will have some similar genetic markers.In a first step we isolate the DNA from the cells of your sample using a method called 'polymerase chain reaction', or PCR. Following this, we do a 'genetic fingerprinting' to find similarities in the DNA samples
As we all inherit our DNA 50 : 50 % from our father and mother we can accordingly find matches in the DNA of 2 or more test participants and therefore conclude on their biological relatedness.
