Attention: Testing services may be reduced or delayed 

For over 90 years the Lab has worked tirelessly to keep Texans safe and healthy. The Department of State Health Services Lab is one of the largest public health laboratories in the U.S. Annually, we test more than 1 million samples for infectious and food-borne diseases, biological and chemical compounds, and biological agents. And every year more than 400,000 Texas babies are screened twice for 54 metabolic and genetic disorders. The lab also helps keep our drinking water safe by testing water from the over 6800 public water systems.
