DNA Relationship Tests – Paternity, Maternity, Sibling & More

DNA relationship tests analyze the genetic profiles of individuals to conclusively determine the nature of their biological relationship. At Precision Lab Works, we carry a full range of at-home DNA relationship tests — from paternity and maternity to sibling, grandparent, twin, and extended family testing — with painless cheek swab collection and private, confidential online results.

Types of DNA Relationship Tests

• Paternity Test — Conclusively confirms or refutes a biological father-child relationship by comparing the child’s DNA to that of the alleged father
• Maternity Test — Determines whether an alleged mother is the true biological mother of a child
• Sibling DNA Test — Determines whether individuals are full siblings, half-siblings, or unrelated by analyzing shared DNA
• Grandparent Test — Establishes whether an alleged grandparent is the biological grandparent of a potential grandchild
• Twin Test — Conclusively determines whether twins are identical (monozygotic) or fraternal (dizygotic)
• Aunt/Uncle Test — Determines biological relatedness between an alleged aunt or uncle and a niece or nephew
• Cousin Test — Confirms or refutes a biological cousin relationship between two individuals
