From Waller County Judge Trey Duhon on March 27, 2020
Below is some information in regards to the Katy testing site. I have requested a testing site for Waller County, but until something is done on that this is the closest testing site for us. Anyone needing to be tested, please follow the instructions below:
The Katy testing site, run by Harris County Public Health, is open from 9 am to 7 pm to general public who qualify – regardless of where they reside. They have to have been approved through the screening system by 4 pm in order to be tested the same day. To access the screening system, call 832- 393- 4220 or visit https://checkforcorona.com/harris-county#/welcome
