A paternity test is a scientific method used to determine whether a specific man is the biological father of a child. This test analyzes DNA samples from the child and the alleged father, comparing genetic markers to establish a biological relationship. Paternity tests are often used in legal situations, such as custody disputes or child support cases. The process typically involves collecting samples through a simple cheek swab or blood test. Results are usually available within a few days and can provide a high level of accuracy, often exceeding 99%. Paternity tests can also help in understanding family medical histories and genetic traits.
