DNA tests
Ancestry lab work
DNA tests are laboratory analyses that examine genetic material to establish biological relationships, identify individuals, or detect inherited conditions.
Paternity tests confirm whether someone is a child's biological father.
Ancestry tests trace ethnic heritage and find distant relatives: I took a DNA test and discovered cousins I never knew existed.
In criminal investigations, DNA tests match biological evidence to suspects.
Home testing kits have made DNA tests widely accessible, though their accuracy for ancestry claims varies.
