DNA tests are genetic tests used to study the DNA sequence for evaluating genetic disorders or proving paternity for legal purposes. DNA is a unique genetic code that carries information from both parents to their children. It can trace an individual's family history and provide information about the genes that make up each individual. The test can help determine if an individual has a genetic disorder and if they have a chance of developing one, as well as confirm abnormal mutated genes that may be passed on to their child.
How Much Does a DNA Test Cost in Nigeria
The cost of a DNA test in Nigeria ranges from N70,000 to N200,000, depending on factors such as location, hospital, test type, and insurance coverage. If you have health insurance, it's important to check with your company's HMO to see if they cover DNA tests. The cost also varies depending on the purpose of the test, such as confirming a child's identity or legal purposes like immigration. Legal tests are generally more expensive than those for peace of mind. It's essential to check with your company's HMO to ensure they cover DNA tests.
An overview of the various types of DNA tests available in Nigeria.
The cost of DNA tests in Nigeria varies based on the type of test, the number of individuals being tested, and the laboratory performing the test.
Prenatal Paternity DNA Test
Prenatal DNA tests are expensive DNA tests in Nigeria, determining if a man is responsible for a pregnancy. The average cost ranges from 800,000 naira to 1,500,000 naira, making them the most expensive in the country.
Paternity DNA Test
A paternity DNA test is a scientific procedure that uses specific DNA markers to determine a child's biological father. It compares the child's DNA sequence with the alleged father's to verify inheritance, providing definitive proof of a biological relationship. The average cost in Nigeria is between 150,000 and 200,000 naira.
Maternity DNA Test
Maternity DNA tests confirm the biological relationship between a mother and child, often used in surrogacy, adoption, or legal or immigration purposes. The average price for a maternity DNA test in Nigeria is between 80,000 naira and 150,000 naira.
Sibling DNA Test:
In Nigeria, the sibling DNA test is a DNA test used to determine if two individuals share one or both parents, often used in cases of paternity or maternity, or in adoption cases, with an average cost of 100,000 naira to 200,000 naira.
Grandparent DNA Test
Grandparent DNA testing, which typically cost between 100,000 and 200,000 naira, can be utilized to determine biological connections between grandparents and grandchildren in situations where parents are not available.
Avuncular DNA Test
Avuncular DNA tests, also known as aunt/uncle tests, are available to determine biological relationships between individuals and their relatives, with an average cost of 100,000 naira to 150,000 naira.
DNA tests typically take 3-5 days from sample collection, with results varying by location. Results can be expected within a week, with some special tests taking longer. However, results can vary significantly.
Different Types of DNA Tests
1. Gene Test
Genetic testing is a method that detects changes in DNA, often referred to as mutations or variants. Gene tests are used to analyze DNA to identify changes in genes that can increase the risk of developing a genetic disorder. These tests can study one gene, a few genes, or all of the DNA, and are referred to as genomic testing, which involves examining all DNA.
2. Chromosome Test
Chromosomal tests are DNA tests that examine the order of genes, or chromosomes, in an organism. These DNA-like structures, organized into genes, are found in the nucleus of each cell. Chromosomes contain genetic information and determine an individual's sex. Males have XY chromosomes, while females have XX chromosomes. Chromosome tests can identify abnormal genetic conditions by detecting changes in gene order, such as an extra copy, missing copy, or rearrangements of chromosome segments
3. Protein Test
Protein tests are essential for analyzing enzyme activity in cells, identifying products of chemical reactions. Issues with proteins can indicate DNA changes that could lead to a genetic condition. Proteins are essential for structural support, hormones, enzymes, building blocks, biochemical catalysts, and initiators of cellular death. Enzymes, proteins in the body that speed up metabolism, are also analyzed in these tests. Any issues with proteins may indicate DNA changes that could potentially cause a genetic condition.
DNA testing results can indicate paternity or genetic disease presence, as everyone inherits a set of genes from their parents. If similar genes or alleles are present in parents and children, the DNA report will reveal that particular gene or allele.
Experts advise against using DNA kits for understanding genetic makeup, recommending instead to go to a certified laboratory for valid results, as these kits may result in false positives or negatives depending on the specific test being conducted.
