A DNA paternity test works a lot like other genetic tests, such as to discover distant relatives, ancestral origins, or even health risks. Now available over the counter, these DNA tests compare samples of a father and child’s genetic code to provide an accurate indicator of paternity. DNA paternity testing is a very reliable way to establish parentage, as tests using current technology are nearly 100% accurate, according to a 2013 study published in the journal Genetics in Medicine

DNA paternity testing obviously isn’t for everyone, but as these kits become increasingly accurate, they serve as a way to determine parentage in all manner of circumstances – from lawsuits to lineage. To give you a better idea of whether it’s something you should consider, here is a guide to how paternity testing works and what kinds of tests are available.
