What is a Paternity DNA Test?
A paternity DNA test is a highly accurate genetic analysis that determines the biological father of a child. It compares the child's DNA profile with that of the alleged father, using specific genetic markers (STRs) to confirm or exclude a biological relationship. DNA Labs India offers both legal and peace-of-mind paternity tests in Chennai, ensuring reliable results with strict confidentiality.
