What is DNA testing?

DNA testing is a scientific method used to identify genetic information from an individual's DNA. It involves collecting a sample—usually saliva, blood, or a cheek swab—and analyzing specific regions of the DNA for markers that can reveal relationships, ancestry, or genetic health risks. The process is highly accurate and commonly used for purposes such as paternity testing, ancestry research, and medical diagnostics. Results are typically available within a few days to a few weeks, depending on the type of test and the laboratory. DNA testing is confidential and regulated to ensure privacy and reliability.
