Use this online search tool to verify a clinical or public health laboratory license issued by the California Department of Public Health. This searchable list is updated daily and is as accurate as current information allows.

Each license record will reflect the status as ‘active’ or ‘inactive’. For renewals that are pending, the status may be shown as inactive as the information is being updated. Please log in to your account to check the application status.

Helpful Tips:

• If the Testing Site State drop-down has been selected as "Other US State" or "Outside of US," do not select anything from the CA County with testing site(s) drop-down menu.
• Depending on volume, exporting search results (PDF or CSV) may take several minutes to download or the system may time-out. Please refine your search as needed.
