The Texas Department of State Health Services (DSHS) performs many specialized tests on a myriad of samples. However, outside submitters cannot always obtain some of these services. Before collecting and/or shipping any sample to the DSHS lab in Austin, please contact the Health District Laboratory to see if 1) they will perform the analysis for you, and 2) if there is a charge for this service. Some services are free when referred through the Health District, while others are not. So it is best to check with us before you collect or send the specimen. You can contact us at (940) 761-7835.
