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 samples to determine whether they are from the same person.
This test can be used to determine if one or more samples are from the same person. This can assist laboratories in accurately assessing their quality systems, or accurately resolve uncertainty regarding the identification of a tissue sample.
Relationship testing is not usually regarded as a component of the medical management of a patient. Nonetheless, the context of the test requires that it be ordered by a medical practitioner. Such collections require the explicit consent of all parties from whom samples are collected. The collection of a sample for genetic testing without consent may be illegal.
Analysis of the number of repeats in highly variable ‘short tandem repeats’ located at multiple points in the genetic code.
This test can be requested by any medical practitioner.
At least two samples are required, for example, fixed or fresh tissue, buccal swab, blood sample, bloodspot.
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.
If this test result potentially has legal implications, the collection requirements will be more stringent than in other contexts. Please contact the laboratory on 1300 663 244 for further information.
