Everything you need to know about the Legal Paternity Test
A paternity test is a genetic analysis that compares a child's DNA with that of an alleged father to confirm or exclude a biological relationship. It is the most accurate and reliable method to establish paternity.
Paternity tests are extremely accurate. The accuracy is over 99.99% when confirming the man as the biological father, and 100% when excluding him.
What does the Paternity Test include?
DNA analysis from a saliva sample taken from:
- Child
- Alleged father
- Mother (optional)
Who is the Legal Paternity Test for?
This test is recommended for anyone who needs to confirm or exclude paternity or maternity with legal validity. It is generally conducted as part of judicial procedures such as inheritance cases, divorces, official recognition, and more.
Where is the sample collected?
Sample collection is carried out at Eurofins-Megalab laboratories, which operate more than 80 labs and collaborate with over 1,000 collection centers throughout the country.
