A DNA sample is any material from a person that contains information about their genetic makeup. These materials can be used to determine a person’s family history, relationships to other individuals, and even proximity to a crime scene. While a DNA sample can be almost anything, there are a few types of samples that are used in most cases. Here’s what you need to know.

How Is DNA Tested?

DNA is tested by comparing multiple samples of human tissue or other materials from the body. Scientists can then look at the sequencing of molecules in those samples to determine the person’s genetic makeup. In the case of relationship testing, two individuals need to have samples collected. Those samples are then compared so that scientists can note the similarities between the two. For example, in a paternity test where a father and child are being tested, the tester would look to see if there are enough consistencies between the two individuals for them to share DNA.

What Are the Types of DNA Samples?

DNA is found in every cell of the body, so there are seemingly endless types of samples. One of the most common is a buccal swab, which is taken by swabbing the inside of the mouth. There are also blood tests, which usually just require a prick of the finger. These two are most commonly used in situations where participants have volunteered for DNA testing, like in the case of paternity or relationship tests. In other instances, like criminal investigations, scientists can also use hair, saliva, fingernails, and skin cells.
