Harris County COVID-19 Testing

Testing locations shown below are managed by various organizations. As a result, availability and operating hours will vary as well as the time it takes for results to be returned. 

Mobile Testing Sites

HCPH COVID-19 mobile testing locations are available throughout Harris County. These locations are updated weekly. Hours may be impacted by weather conditions.

*Mobile testing sites operated by TDEM require registration through https://txcovidtest.org.

Stationary Testing Sites

In addition to mobile testing sites, HCPH also helps organize stationary (or fixed location) sites within Harris County. 

Surge Testing Sites

In partnership with the US Department of Health and Human Services (HHS), HCPH helps manage surge testing sites in the area. 

Alternate Testing Sites

In addition to stationary (fixed) and mobile sites operated by HCPH and our partners, there are numerous alternate sites managed by organizations like CVS Pharmacy, Walmart, and more. Please note that HCPH does not manage these locations or their availability. For more information about operating hours, scheduling an appointment, and acquiring test results, contact the facility directly. 

More testing sites may be found on the TX COVID-19 Test Collection Sites Map compiled by the Texas Department of State Health Services (DSHS) and URISA GISCorps.

Acquiring Test Results

The process for acquiring test results will differ based on the location visited and whether the facility is operated by Harris County Public Health (HCPH). For locations not operated by HCPH (i.e., Alternate Sites), you must contact the facility directly for information regarding test results.
