DNA testing is the most accurate and advanced technology till now to determine maternity or paternity test. A child inherits nearly half of the genes from both parents. A standard paternity test is used to prove father-child relationship conclusively. If the alleged father is not related to the child biologically then paternity test result probability should be 0% and more than 99.9% if he is biologically related to the child.
If the mother of the child is willing to participate in the test, then it helps to exclude half of the DNA of child inherited from her. It makes data analysis easier. But it is not essential if the mother is unable to participate, a motherless paternity test can be carried out which is also conclusive and equally accurate.
The legal paternity test follows a strict chain of procedures to make it legally admissible. It is used as an evidence for inheritance, child support, immigration, adoption, or social welfare benefits. Some of the parents choose prenatal paternity test that is conducted before the birth of the child. The non-invasive prenatal paternity test is conducted through mother’s blood sample or buccal swab sample with 99.99% accuracy to verify paternity of developing the child.
The non-invasive prenatal paternity test can be conducted as early at 9 weeks from gestation and very safe due to a non-invasive method. Some of the parents go for paternity DNA test just for the peace of mind that is called standard paternity test. A standard paternity test can be carried out at home using home sampling collection as it doesn’t require a strict chain of procedures as needed in a legal and Confidential paternity test.
