Relationship Testing

Also known as: Paternity/Maternity/Other Relationship

« Back to test list


Some portions of the genetic code are highly variable. These variable regions will frequently be similar in related individuals, but different in unrelated individuals. This test assesses a minimum of 15 highly variable regions of the genetic code between two or more individuals to determine their degree of biological relationship.

Clinical Utility

The laboratory will provide an interpretation of the results, indicating the likelihood of the identified parties being related or not.

This is not a medical test. It can only be ordered by the patient or client, and requires the explicit consent of all parties from whom samples are collected. The collection of a sample for genetic testing without consent may be illegal.


Not specified

Test Method

Analysis of the number of repeats in highly variable ‘short tandem repeats’ located at multiple points in the genetic code.

Test Ordering

This test is requested by private application rather than through a medical practitioner. The psychological, ethical, and legal consequences that may arise from the test result should be considered before requesting this test. The collection requirements for this test will vary depending on the purpose of testing. If the test is required for legal purposes, the collection requirements are more stringent than if the test does not need to fulfil these requirements. A specific request form must be used (see link below).

Blood sample, buccal swab, or tissue sample.

To help ensure the quality of the test, a genetic test should be done with a dedicated sample whenever possible i.e. a sample collected specifically for that test rather than a sample that is used for multiple tests.

We also recommend that the patient or another adult check the labelling of request forms and sample tubes.
