DNA Paternity Test: What It Is, How It Works, and Why It Matters

A DNA paternity test is the most reliable method to confirm whether a man is the biological father of a child. It is used for several purposes; legal matters, personal peace of mind, birth certificate updates and inheritance claims.

One day while I was in my clinic, my phone buzzed: incoming call! It was one of my friends, who is also a patient at Helal Medical Manila. I picked up my mobile asking what was up. He was hesitant to talk straightforward. After few moments, he asked about a DNA test. I replied, but he shrugged off my reply: ‘No, I don’t mean this.’

‘Then what?’ I asked. He clarified that he meant a DNA paternity test. It was first time someone asked about this test, it wasn’t on our list of tests. Hence, because he wasn’t an ordinary patient, but a friend, we dipped into a long conversation; worry, doubt, and uncertainty.

In this article, I will explore what a DNA Paternity Test is, and how it works. I will also cover why some couples desire to undergo DNA testing. Continue reading Read on to get clear answers and be informed for yourself and your family.

What Is a DNA Paternity Test?

This test compares the genetic material of a child and the alleged father to see if they match. Every person inherits half their DNA from their biological mother and half from their biological father. If the man tested is not the father, his DNA will not match the child’s genetic pattern.

Accuracy:
Nowadays, tests are over 99.9% accurate when confirming paternity, and 100% accurate when excluding it. Results are scientifically proven and accepted by courts and government agencies.

How It Works

1. Two Main Types

• Personal Test for Peace-of-Mind:
  For your own knowledge only, results are not used legally. You can collect samples at home and send them to the lab.
• Legal Test:
  Ate accepted by courts and government offices. It must follow strict rules: samples are collected by authorized staff, ID is verified, and paperwork must be sealed properly.

2. Collection Process

• Buccal Swab:
  A soft cotton swab is rubbed inside the cheek to collect cells. It is painless, safe for both babies and adults.
• Other samples:
  Samples like blood, hair with roots, or saliva can be used. But cheek swabs are preferred for ease and reliability.

3. Steps

1. Contact an accredited lab to arrange collection.
2. Bring valid IDs and required documents for legal cases.
3. Swabs are taken from the child, alleged father, and mother (optional but recommended) .
4. Samples are sent to the laboratory for analysis.
5. Results are released within 3–10 working days depending on the service chosen; personal or legal.
