Paternity testing is carried out usually using swabs from the mouth, but can also use blood and hair.
To get a paternity test, you can:
Contact a laboratory yourself (they will ask you to choose a GP to do the tests)
Go to a specialist agency that will organise the test for you
Après ca va dans les 2 sens, la femme peut également exiger un test de paternité au cas où t'aies fait ton nègre a baiser sans capote et parti sans assumer
