DNA Paternity Test

The DNA Paternity Test is a genetic test used to determine whether a man is the biological father of a child. It analyzes DNA markers inherited from both parents to establish a biological relationship with over 99.99% accuracy.

Purpose of the Test

This test is used for:

• Legal paternity cases, including child support, custody, and inheritance claims.
• Personal confirmation of biological relationships.
• Immigration applications that require proof of biological parentage.
• Medical history tracing, as some genetic conditions are inherited.

Test Procedure

• Sample Collection: DNA is usually collected from a buccal (cheek) swab or a blood sample from both the child and the alleged father. The mother’s sample may also be included but is not always necessary.
• DNA Analysis: The laboratory examines specific genetic markers and compares them between the child and the potential father.
• Result Interpretation:
  • A match (99.99% probability or higher) confirms biological paternity.
  • A mismatch (0% probability) excludes the tested man as the father.

Accuracy and Reliability

• The test provides highly accurate results when conducted in an accredited laboratory.
• Legal DNA tests must follow strict chain-of-custody procedures to be valid in court.
• Non-legal (at-home) tests are available but are not accepted for legal purposes.
