How to Read Your Paternity DNA Test Results


Paternity DNA tests have become increasingly popular in recent years. They can provide vital information for families who want to know the biological relationship between a child and a potential father. While taking the test is one thing, understanding the results can be daunting for many people. This blog post will discuss how to read your DNA paternity test at home results clearly and concisely.

Understanding the Basics of a DNA Paternity Test at Home 

Before we dive into the specifics of reading your paternity DNA test results, let’s take a moment to understand the basics of a DNA test. DNA stands for deoxyribonucleic acid, the genetic material of our bodies. It contains a unique sequence of nucleotides that determines our genetic traits, including physical characteristics and traits inherited from our parents.

A paternity DNA test works by comparing the DNA of the alleged father and the child to determine if there is a biological relationship. The test looks for specific markers in the DNA sequence shared between the two individuals. The more markers that match, the more likely the two individuals are related.

Types of Paternity DNA Tests

There are two main types of paternity DNA tests:  Legal and non-legal. 

  • A Legal DNA Test 

It is typically required for legal purposes such as child custody, immigration, or inheritance disputes. A medical professional usually administer these tests, and the results are legally binding.

  • Non-Legal DNA Test

These tests are often used for personal reasons, such as peace of mind or family history research. These tests can be purchased online or at a pharmacy; the results are not legally binding.

Understanding your Paternity DNA Test Results

Once you have received your DNA paternity test at home results, the first thing to look for is the overall probability of paternity. This number indicates the likelihood that the alleged father is the child’s biological father. In most cases, the probability of paternity will be expressed as a percentage, such as 99.9% or higher. A 99% or higher probability is generally considered conclusive proof of paternity.

The next thing to look for in your paternity DNA test results is the genetic markers that were tested. These markers are specific locations on the DNA sequence used to compare the DNA of the alleged father and the child. The number of markers that were tested can vary depending on the test type, but it is typically between 16 and 21 markers.

The test results will indicate which markers match the alleged father and the child. A match indicates that the DNA at that marker is identical for both individuals. If the DNA at a marker does not match, it means that the alleged father is not the child’s biological father.

The non invasive prenatal paternity test Richardson results may also include a genetic profile for each individual. This profile shows the specific DNA sequence for each person, which can be useful for future reference if further testing is required.

Interpreting your Paternity DNA Test Results

If the probability of paternity is 99% or higher and all tested markers match, it is likely that the alleged father is the child’s biological father. However, if the probability of paternity is lower or some markers do not match, further testing may be required to confirm the relationship.

If you are unsure about how to interpret your DNA paternity test at-home results, it is always best to seek the advice of a medical professional or genetic counselor. They can provide additional information about the test results and answer any questions.

Things to Remember

If you have taken a paternity DNA test and have received the results, here are some steps you can take to read and understand the information:

  • Check the Accuracy of the Results: The first thing to do is check the results’ accuracy. Look for the confidence level, which is expressed as a percentage. The test is very accurate if the confidence level is 99% or higher.
  • Look for the Genetic Markers: Next, you should look for the genetic markers used in the test. These markers are typically identified by letters, such as A, C, G, and T. You will see a list next to each person’s name.
  • Compare the Genetic Markers: Compare the genetic markers between the alleged father and the child. Look for matches or similarities between the two sets of markers. If the markers match, then it is highly likely that the alleged father is indeed the child’s biological father.
  • Look for Exclusions: Look for genetic markers that do not match the alleged father and the child. These are called exclusions. If there is too much exclusion, then it is highly unlikely that the alleged father is the child’s biological father.
  • Seek Professional Help: If you have difficulty understanding the results or have any questions, it is always best to seek professional help from a genetic counselor or a healthcare professional.


In conclusion, reading your paternity DNA test results can be straightforward once you understand how DNA testing works. The key is to look for the probability of paternity and the markers that were tested and to compare the results to the expected outcomes.
