How DNA Paternity Testing Works: The Science Explained Simply

In today’s world, DNA paternity testing has revolutionized how families uncover the truth about biological relationships. For individuals in Malawi, Zambia, and across Africa, understanding the process behind this incredible scientific breakthrough is crucial. This article simplifies the science, making it easy for everyone to grasp how DNA paternity testing works and why it is so reliable.

What Is DNA?

DNA, or deoxyribonucleic acid, is the unique code found in nearly every cell of the human body. It acts as a blueprint, determining everything from eye color to genetic predispositions. Since half of a person’s DNA comes from their mother and the other half from their father, DNA is the gold standard for determining biological relationships.

Step-by-Step Breakdown of DNA Paternity Testing

1. Sample Collection

The first step in DNA paternity testing is collecting a sample of genetic material. This process is straightforward, non-invasive, and painless.

• Cheek Swabs: The most common method involves rubbing a soft swab inside the cheek to collect cells.

• Other Samples: While cheek swabs are preferred, alternative samples like hair follicles or saliva can sometimes be used.

Samples are collected from the child, the alleged father, and, optionally, the mother. Including the mother’s DNA can improve accuracy but is not always necessary.

2. DNA Extraction

After collection, the samples are sent to a laboratory where technicians isolate the DNA.

• Cell Breakdown: Chemicals are used to break open cells and release the DNA.

• Purification: The DNA is then separated from other cellular materials to create a clean sample ready for analysis.

3. DNA Amplification

Once the DNA is isolated, it is amplified using a technique called Polymerase Chain Reaction (PCR). This process creates millions of copies of specific DNA sections, ensuring there is enough material to analyze.

4. Genetic Marker Analysis

The heart of DNA paternity testing lies in analyzing specific genetic markers.

• What Are Genetic Markers? These are unique DNA sequences that are passed from parent to child. Scientists focus on markers shared between the child and the alleged father.

• Comparing Markers: If half of the child’s markers match the alleged father’s, paternity is confirmed with high certainty.

5. Probability of Paternity Calculation

Once the markers are analyzed, the lab calculates the Probability of Paternity, expressed as a percentage. This figure shows how likely it is that the tested man is the biological father.

• 99.99%: Confirms paternity.

• 0%: Excludes paternity.

6. Results Delivery

Results are compiled into a clear, easy-to-understand report and shared confidentially. Most labs, including DNA Hub Africa, deliver results within 7-10 business days. Options for receiving results include:

• Online portals

• Secure in-office collection

• Confidential mail delivery
