Parentage testing now applying the DNA profiling method allows direct investigation of the genetic material inherited from the parents to the child. Using recent PCR technology DNA analysis enables the determination of paternity or maternity with an accuracy of 99,99 % and higher.
To determine suspected paternity, the examination of the child, the mother and the putative father(s) is required.
If it is not possible to include the child’s mother, paternity still can be determined with the child and the father, though at a lower level of certainty.
This also applies to cases where the putative father cannot be examined as in case of death. Descent can be clarified by testing the paternal grandparents or siblings of the putative father.
Even more complex family relationships may be confirmed or excludes by means of DNA analysis. As potential success varies with the degree of relationship of the respective persons, preceding consultation is strongly recommended.
All materials necessary for proper collection and shipping of samples are provided by our laboratory. The following specimens are suited for analysis:
- 1 ml blood anticoagulated by EDTA
- 2-4 buccal swabs (each person to be examined)
- tissue material from autopsy or biopsy; dried blood spots; hairs with roots (at least 5-10)
- amniotic fluid: 10-20 ml of native, untreated fluid or cultured amniocytes
- chorionic villus sample: 100 mg of sample or 20 ml of cultured cells
Specimen should be collected by a physician or medical staff familiar with blood collection. Collection is documented on a special form to ensure identity of samples to be examined.
Our laboratory is working according to GLP (good laboratory practice) guidelines and has been accredited in accordance with the European DIN EN ISO/IEC 17025:2018 (D-PL-13432-01-00) standard.
