You submit a a mouth swab and it is sent to a laboratory and scientists there use tests to decipher your DNA.

For most DNA tests such as a paternity test or sibling test, the procedure is the same. They perform a polymerase chain reaction in order to get a DNA profile.

If two profiles are related they show similar patterns.
