HLA Test: A Comprehensive Guide to Its Legal Implications and Applications

Definition & Meaning

The HLA test, or human leukocyte antigen test, is a type of blood test used to determine genetic compatibility, particularly in paternity cases. This test analyzes specific proteins on the surface of white blood cells, which are known as antigens. By comparing the HLA antigens of a mother, child, and alleged father, it can help establish biological relationships. If an antigen present in the child cannot be traced back to either the mother or the alleged father, it indicates that the alleged father is not the biological parent.

Real-world examples

Here are a couple of examples of abatement:

Example 1: A mother seeks to establish paternity for her child to secure child support. She requests an HLA test to confirm the identity of the biological father.

Example 2: An alleged father doubts his paternity and requests an HLA test to clarify his relationship with the child. The test results show that one of the child's HLA antigens cannot be matched to either parent, confirming he is not the biological father.
