Relationship Tests

DNA analyses are the most accurate way to confirm or refute biological relationships. A simple and painless buccal (mouth) swab sample is collected from each individual. The sample contains cells, and most of the cells in our body contain a full set of genetic information in the form of DNA (deoxyribonucleic acid). A person’s DNA represents a “genetic blueprint” and, like a fingerprint, it is unique to each individual. At the laboratory, the DNA is extracted from the cell and specific regions of the DNA are amplified by a process known as PCR (polymerase chain reaction). The DNA patterns of the individuals are compared to determine if they are biologically related.

For parent-child relationships (paternity and maternity tests), these genetic analyses provide greater than 99.9% probability of a biological relationship for inclusions and 100% for exclusions. For other relationship tests, an index value is provided, which indicates the likelihood of a biological relationship.

Genovate offers two options for each relationship test:
  • Private Home Kit: Ideal for families who wish to determine the truth about a biological relationship in private before deciding on the next step. The mouth swab can be collected discreetly using a private home kit and sent to our laboratory for analysis.
  • Legally Admissible Testing: The results of this analysis are accepted in courts throughout North America as legal evidence of a biological relationship. An appointment for a chain-of-custody sample collection is arranged to ensure witnessing and fingerprinting of the parties involved in the test.
