Determining the biological relationship between two people through DNA testing is simple, inexpensive, and more accurate than ever before. Paternity tests are the most common form of DNA testing, but we also offer DNA testing for relationships such as siblings, grandparents, aunts, or uncles.

You can obtain a DNA test at your nearest Health Street collection site, or by using one of our DNA home testing kits. We also offer specialty testing, including post-modem and prenatal DNA tests. While a cheek swab is the most common method of collecting a DNA specimen for a relationship test, alternatives like hair, semen, or fingernails can also be used.

About DNA Test and Home Testing Kits

Which Relationships Can you test for?


The following DNA tests are available to confirm or rule out close family relationships:

  • Paternity Test - Father to child
  • - Mother to child
  • - Grandparent to grandchild
  • - Aunt or Uncle to niece or nephew
  • - Brother to Sister (Sibling to Sibling)
  • - Half-brother to Half-sister (Half-sibling to half-sibling)
  • - Identical Twins vs. Fraternal Twins

How does DNA Testing Work?


DNA testing to prove - or rule out - close family relationships is a three step process.

  • 1) Specimen Collection - Specimens can be collected at home and shipped using one of our home test kits, or by scheduling an appointment at one of our testing clinics.
  • 2) Laboratory DNA Extraction- A certified laboratory extracts the DNA from the provided specimens.
  • 3) Statistical Analysis - A doctor compares the allele sizes of the 21 chromosomes and signs off on a statistical analysis which determines the likelihood of the biological relationship between the parties.

DNA Collection Methods?

  • 1) Cotton Swabbing
  • 2) Hair Follicle
  • 3) Fingernails

DNA can be extracted from a variety of specimens. The easiest to obtain, and therefore the most common source of genetic material for relationship testing, is buccal cells. Buccal cells are the skin cells of the inner cheek, which rub off easily onto cotton swabs.
