The genetic fingerprint of each person is unique. On comparing the genetic pattern of father, mother and child, exactly half of the paternal features are found in the child, while the other half stem from the mother. Using this as a basis, this test allows to exclude a putative father, for example, with a certainty of more than 99.99%.

The paternity index is also determined as a criterion of paternity. Results are conveyed to the doctor and the test persons in the form of a report that is free of charge. A court, guardianship authorities or an migration authority, for example, may act as clients.

We guarantee completion of the process within 14 days of sampling. Absolute discretion is ensured at all times. Viollier AG is authorized to establish genetic profiles under the Swiss Federal Law on the genetic testing of humans and the accompanying ordinance.

Indications

• Paternity test, uncertain maternity: Who may be tested?

• Clarification of special cases, elucidation of relationships (following consultation by telephone)
• Twin testing: identical (monozygosity) or nonidentical (dizygosity)
• Determination of genetic sex (athlete certification)
• Bone marrow donors and recipients

Procedure

Subjects, doctors or authorities should contact the relevant member of the Viollier consultation team directly for the subsequent procedure. The doctor receives the relevant sampling kit and the special order form on request and at the same time the following documents should be presented:

• Written consent from the mother if she is not tested at the same time.
• Copy of identification documents, signed by the persons involved
• Copy of the Family Record Book with the children's birth certificates
• The order form with the doctor's signature and that of the test persons present. The latter are informed by the doctor about the legal recommendations, which are printed as a legal text on the forms.

Diagnosis

DNA is isolated from a cell smear from the inside of the cheek or from EDTA blood and a so-called DNA fingerprint is established. For this, PCR (polymerase chain reaction) of 16 STR (short tandem repeat) loci is performed and at the same time a locus is also studied to determine the sex. The chromatographic separation of the allele DNA fragments and their detection by fluorescence yields the individual genetic fingerprint.
