Paternity and Maternity testing
Determination of paternity – maternity
Paternity/maternity tests are performed when it is necessary to determine the biological origin of a child.
The test is based on the fact that each person inherits half of their DNA molecules (chromosomes) from their mother, and half – from their father. In order to determine the biological origin of a child, the profiles of DNA molecules of the possible father, the child, and the mother are compared. The DNA profile (STR genotype) is almost unique for each person, since the probability that two males who are not blood relatives might have an identical DNA profile is extremely low. This property of DNA profiles is also used in the paternity test in order to determine the biological origin of a child.
The accuracy of the paternity test is directly proportional to the number of DNA regions (loci) to be tested. In recent history, DNA profiles with 10 DNA loci were compared in paternity tests in Latvia. Today, a DNA profile in which at least 15 DNA loci are compared in samples of a man, a child and a woman is recognised as the best method for proving paternity. Already for the second year GenEra laboratory compares results in 24 loci.The loci to be analysed are determined by international forensic institutions, therefore today almost all laboratories test the same set of loci and the results are often compatible.
SIA GenEra offers paternity determination with AmpFlSTR® Identifier Plus™ system, developed by Applied Biosystems, an acknowledged leader in the field of DNA testing. This system allows analysing 24 DNA loci.
The method is registered and certified by the Health Statistics and Medical Technology Agency, code La/MoB 068, and is accredited in accordance with the requirements of the standard LVS ISO 15189:2013.
