Prenatal Paternity« 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 mother, father and the fetus to determine whether they are genetically related.
This test provides an accurate indication of whether the man tested and the fetus are close genetic relatives.
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 may only be requested by a medical practitioner. The psychological, ethical, medical and legal consequences which may arise from the test result should be considered before requesting this test.
Chorionic villus sample or amniotic fluid plus blood sample or buccal swab from mother and father tested.
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.
This test involves collection of the fetal sample by an obstetrician. Please contact the laboratory on 1300 663 244 as pre-booking and a collection kit are required for the day of sample collection.
