How to Prepare for a DNA Paternity Test: A Step-By-Step Guide

Day by day, many new initiatives and inventions are taking place around the globe, especially in science-related fields. The discoveries have endless potential and could drastically change our lives for the better. Among them, one truly satisfying and splendid discovery is discovering relatives through DNA tests.

Many genetic tests are available now, and the paternity test is the most popular and widely used. A paternity test works like any other test that involves a comparison of the DNA samples of a father and a child and then analyzing their genetic codes to get an accurate result of the paternity.

If you or anyone close to you is preparing to take one of these tests, there is some basic information that must be known beforehand. Here is everything you must know about taking a DNA paternity test.

The Ultimate Selection For The DNA Paternity Test


The technique used to determine the results in these tests is certainly 100% accurate as it uses advanced and currently available technology that offers error-free outcomes.

These tests might come across as unreliable at first; however, over time, it has been established that they are genuinely a better option to solve the question of anyone’s patronage and are highly accessible as many companies offer DNA testing kits.

It is possible to carry out genetic tests at medical clinics or even at home with the available kits for each option in the market. The results acquired from both tests taken at home or clinic have similar outcomes, as every test kit should be tested and licensed with the same laboratory techniques.

The type of kit you choose for the test also depends on individual preferences. Using the ones that can be tested at home is better for a relaxed approach. However, suppose the purpose is related to legal actions. In that case, carrying out the test in a hospital is recommended.

The Beginning Of The Paternity Tests: A Brief History

The olden days witnessed the many discoveries of scientists proving how genes are passed from parent to child. But the possibility of a DNA test was not in the hope of anyone from the science field. Fast forward to almost ten years later, today, it is possible and accessible to anyone in need.

The first tests that were introduced to the world utilized blood samples of the child, mother and potential fathers to determine and rule out the options depending on the child’s blood type. Unfortunately, even though there was a way to determine the result, this method of taking inferences from blood types was limited and entirely accurate.

Thanks to the constant study and research of scientists and medical professionals and the involvement of evolving technology, it is now possible to have accurate results within a few simple steps without any hassles.

As a result, paternity tests have become more common than ever. It is also possible for any citizen to take them to finalize their true identities and origins.

Steps Involved In The Paternity Test: An Overview


The entire process of DNA test involves different steps, including sample collection, DNA isolation, downstream processing and analyzing the finally obtained results.

Collection Of The Required Sample

Except for the red blood cells, every other cell in the body contains DNA. Therefore any cell type can be used for the test. However, the commonly used ones are blood cells. Additionally, buccal swab samples are collected from inside the mouth with a plastic stick with cotton wrapped at one end.

After the sample collection, they are sent to the DNA testing labs and stored and maintained at appropriate temperatures.

Extraction Of DNA

To perform a test and to get successful results, the obtained DNA should be of good quality. The common method for extracting and isolating DNA in paternity tests is polymerase chain reaction-based amplification.

First, the extracted DNA will be forwarded to process the sample for the polymerase chain reaction to get many copies of DNA. Then, the DNA gets separated further at a higher temperature, and the rest of the process involved is entirely technical.

Analyzing The Final Results

The final step in the test is to analyze and determine the final results. First, a medical professional will analyze and separate each DNA band and interpret the relationship between DNA samples.

Further, the number of matching DNA bands between the child and the potential father is also calculated. And by matching, the final result will be determined and concluded, which is usually accurate.

Using Paternity DNA Test Kits At Home

If you have decided to try the DNA test kit at home, first, you must fill out all the consent forms that will be given along with the kit. Everyone participating should sign the forms. Then, a sample envelope inside the kit will be used to fill in the basic information and label one envelope per person.

The kit also has oral swabs that should be removed and gently rubbed against the inner cheek for almost one minute. Do the process firmly but gently to obtain better results. Repeat this process two times per each person involved in the test. Next, place the swabs in a dry area without touching or disturbing them and allow them to dry for up to one hour.

Now remove the swabs, place them inside the appropriate envelope, and seal each. Always ensure not to mix the swabs and envelopes of the people involved. After everything is properly included, along with the sample collection and the consent forms, you can parcel it to the address of the DNA testing place to get accurate results within a few days.



Preparing for a paternity test includes deciding which type of test you want to take. Whether for legal actions or personal reasons, the type of test could vary depending on the purpose.

Further, proper DNA samples and basic personal information will be enough to determine and analyze the final results. Lastly, choose a trustworthy DNA testing specialist for a seamless and hassle-free experience.
