Tick Identification & Info
The District can identify resident-submitted ticks but DOES NOT perform disease testing on resident-submitted ticks.
Learn more about why CDC does not recommend testing individual ticks as part of tick-borne disease prevention risk. Learn more about what to do after a tick bite.
If you want a tick tested, check with the San Mateo County Public Health Laboratory to see if they are currently offering tick testing.
The District laboratory conducts surveillance for tick-borne pathogens at parks and open spaces throughout San Mateo County. These results are available on the Tick Surveillance page.
