Usage
Determination of parentage for child support, legal proceedings, and Vital Statistics (birth certificates).
Age Limit
DNA testing can be performed on patients at any age.
- Prenatal Testing: Chorionic Villus Sampling, Amniocentesis. Please ensure that an appointment for prenatal sampling can be arranged with an obstetrician prior to ordering DNA test.
- Testing at Birth: Umbilical cord blood (please call Genetrack to arrange for testing prior to date of birth).
