DNA (Deoxyribonucleic acid) testing is a powerful scientific tool that provides definitive information about biological identity and relationships. This technology analyzes an individual’s unique genetic code, and its use is rapidly increasing within Nigeria. People seek DNA testing for personal reasons, such as confirming a biological relationship, or for official matters. Demand is growing for legal purposes, including inheritance claims, court proceedings, and family reunification under international immigration rules. This guide provides an overview of the different types of DNA tests, their associated costs in Nigerian Naira (NGN), and the factors that influence the final price.
Primary Types of DNA Tests Available
Genetic testing services in Nigeria generally fall into three distinct categories based on their purpose and methodology. The most commonly sought services are relationship tests, which determine the probability of a biological link between two or more individuals. These services usually involve a simple, non-invasive cheek swab (buccal swab) collected from the participants. Paternity testing, which determines if a man is the biological father of a child, and maternity testing are the most frequent applications.
A second major type is testing required for legal or immigration purposes, which demands a strict chain of custody. This process ensures the sample is collected and handled in a way that is legally admissible in a court of law or by an embassy. The third category includes health, wellness, and ancestry screening. These tests analyze genetic markers for predisposition to certain diseases or to trace ancestral origins across populations.
Typical Price Ranges for Key DNA Tests
The cost of DNA testing services varies significantly depending on the type of test and the required outcome. For a standard private paternity test, often referred to as a “peace of mind” test, the typical cost ranges from NGN 50,000 to NGN 250,000. This price usually covers the testing of the alleged father and one child, providing results for personal knowledge only.
Testing for legal or immigration matters carries a substantially higher price tag due to the necessary regulatory compliance. A legal paternity test, which includes court-admissible documentation and strict chain-of-custody procedures, generally falls between NGN 300,000 and NGN 600,000. Similarly, immigration DNA tests for visa applications are priced within this elevated range, starting at approximately NGN 350,000.
The most complex relationship test is the Non-Invasive Prenatal Paternity Test (NIPPT). This specialized test can determine paternity as early as the tenth week of pregnancy using only a blood sample from the mother and a buccal swab from the alleged father. The cost for NIPPT can range widely, from NGN 800,000 up to NGN 2,800,000, reflecting its technological complexity.
Factors Influencing the Final Testing Cost
The broad range in pricing for similar tests is determined by several specific variables beyond the basic analysis. One significant cost factor is the processing location of the genetic sample. Many Nigerian collection centers partner with international laboratories, often in the United States or Europe, for the actual analysis. Shipping samples overseas increases the final bill to cover international logistics, customs, and the foreign lab’s processing fees.
Turnaround time also directly impacts the expense, as laboratories charge a premium for expedited services. While standard processing might take 10 to 15 business days, requesting results in three to five days can significantly increase the total cost.
The type of sample collected is another variable. The most common and least expensive is the buccal (cheek) swab. Testing non-standard samples, such as blood, hair, or forensic samples, may require complex extraction techniques that add to the analytical cost.
Finally, strict legal requirements associated with court or immigration cases necessitate added costs. The chain-of-custody procedure is labor-intensive, involving independent witness verification, photo identification, fingerprinting, and secure shipping. This rigorous documentation contributes substantially to the difference between a private and a legal test price.
Selecting an Accredited Testing Center
Choosing a reliable provider requires careful consideration of the center’s credentials and service scope. For any test intended for official use, such as immigration or legal proceedings, choose a center that uses a laboratory with recognized international accreditation. The American Association of Blood Banks (AABB) accreditation is the global benchmark for relationship testing and is often required by embassies and courts.
It is helpful to understand the difference between a sample collection center and a full-service laboratory. Many local centers are collection points that handle sample collection and secure shipping to an internationally accredited partner lab for analysis. Before proceeding, individuals should inquire about the necessary documentation, particularly for minors or legal cases. Proper identification, such as a valid government-issued ID or passport, and written consent forms are mandatory.
