Tick Identification

The District laboratory CANNOT test resident-submitted ticks for Lyme disease or other pathogens. If you are bitten by a tick and would like to have the tick tested, please make sure that the tick remains alive and is contained in a slightly humid environment like a small jar or a plastic bag containing a moist piece of paper towel. Ticks can be brought to the District office for identification only or submitted to the County Health Laboratory, located at 225 West 37th Street, Room 113, San Mateo, California for testing. For more information, call (650) 573-2500.
