At What Age Can a DNA Test Be Done on a Child in Nigeria? A Comprehensive Guide

The advent of DNA testing has significantly transformed how we establish biological relationships, resolve legal matters, and understand our ancestry. One common question that often arises, particularly in the context of paternity testing, is about the appropriate age for a child to undergo a DNA test. If you’re based in Nigeria and are considering a DNA test for your child, this blog post provides critical insights about the most suitable age for DNA testing and the related considerations.

Age is Not a Barrier in DNA Testing

The first thing to understand is that there is no minimum age requirement for a DNA test. A child can be tested for DNA at any age — even right after birth or while still in the womb. The child’s age does not impact the accuracy of the test because a person’s DNA remains the same throughout their lifetime.

DNA Testing in Newborns

Newborns can undergo DNA testing right after birth. Hospitals in Nigeria can collect a DNA sample from a newborn using a buccal swab or a blood sample. This non-invasive process involves gently rubbing a soft swab on the inside of the baby’s cheek to collect cheek cells or taking a small blood sample. Both methods are safe for newborns and cause minimal discomfort. The samples are then analyzed to extract the baby’s DNA for testing.

Prenatal DNA Testing

As discussed in our previous posts, it’s even possible to conduct DNA tests while the baby is still in the womb. Non-Invasive Prenatal Paternity (NIPP) testing, a cutting-edge procedure, can establish paternity as early as the 7th week of pregnancy by analyzing cell-free fetal DNA in the mother’s bloodstream.

Important Considerations

While age isn’t a factor in the effectiveness or accuracy of a DNA test, certain considerations are crucial when testing a child:

Consent: Consent plays a pivotal role in DNA testing. For minors, consent must be provided by a parent or legal guardian. In some cases, consent from both parents might be needed.

Purpose of Testing: The purpose of the DNA test can influence when it should be done. If the test is for establishing paternity for legal reasons, it’s best to conduct the test as soon as possible to expedite legal proceedings.

Choosing a Reputable Laboratory: Not all laboratories provide the same level of service. It’s crucial to select an accredited, reliable laboratory that adheres to international standards of DNA testing.


In conclusion, DNA testing can be done at any age, whether the child is a newborn, an older child, or even still in the womb. The primary considerations are not the child’s age but ensuring the appropriate consent is given, understanding the purpose of the test, and choosing a reliable laboratory.
