Scientific Background

A paternity test can confirm a biological relationship between a putative father and a child.

Each of our body's cells contain a complete set of our DNA.
The DNA determines e.g. the colour of our eyes and hair. It consists of small repeating blocks, the so-called "bases" A, T, C and G.

With the birth of a child the DNA code of mother and father are passed on to the child through the sperm and egg. The child receives a unique set of genetic material. Knowing this, the father can be determined by comparing the child's DNA with that of the putative father. Usually, specific sequences are examined for sameness.
