• You are in doubt of your paternity
• You are uncertain of your blood relation to your relatives
• You require an legal expert’s proof for court
• You would like to clarify issues regarding claims of inheritance.

A paternity test will be carried out after written order and sampling:
 
Samples will be taken at our laboratory or we send a testkit to you containing swabs and instructions.
 
You can choose between a private and a legally certified expertise as proof for court (note that there is no difference in the technical features):
 
For a private report, you come to our lab during opening hours or at appointments arranged with our staff or you contact us so that a sampling kit is sent to you.
 
For a proof by one of our legally certified experts, please make an appointment

A maternal sample is (with few exceptions) not mandatory for paternity testing.
There are, however, certain advantages of including the mother:

• The identity of the child’s sample is secured.
• The obligatory paternal alleles become evident and we attain a higher probability of paternity, therefore the biostatistical calculation and conclusion is more accurate.
• Constellations leading to an exclusion of paternity are better defined by identifying the alleles in the child’s pattern that are inherited from the mother.
• If a close relative of the tested alleged father is considered as potential father as well (for example the brother), we need to be informed and a maternal sample is obligatory

a child that shows one allele corresponding to the mother and the other one to the alleged father at each examined marker position, paternity cannot be excluded.
We calculate the likelihood based on an exact modelling of hypothesis for the postulated varieties of relationship. Our biostatistics software “GenoProof” determines the probability of paternity based on the genotype frequencies in the individual population.
 
A probability of paternity will never be exactly 100% because of the theory of probability and the nature of this calculation, but it will be near to this value and it signifies a proven paternity. In the case of an excluded paternity the value is indeed 100%.
Therefore, the report you receive will confirm your paternity to at least 99.999% (minimum 99.99% without the sample of the mother) or exclude it to 100%.
 
With a total of more than 60 marker systems, we are perfectly equipped to deal with special cases and more difficult calculations.
The more marker systems are analysed, the more information, power of discrimination and higher probability we get.
 
We also take into account the genetic descent of each person (ethnic population) in the calculated probabilities and apply the “step-model” for mutations when needed.

In deficiency cases when the sample of one of the persons is missing, e.g. when the alleged father is deceased, this sample can be substituted with samples from the person’s parents.
Other possible indirect paternity tests include:
Grandfather or uncle test (Y-chromosomal = male inheritance),
grandmother test (X-chromosomal inheritance), sibling analyses (X-chromosomal between alleged sisters, Y-chromosomal between alleged brothers).
 
For an indirect maternity test we perform sequence analysis of mitochondrial DNA.
