For patients


Where to get a tuberculosis (TB) test
Public Health - Seattle & King County no longer provides TB testing for work or school purposes. This service can be provided by your private medical provider, community health center or occupational health clinic.


For health care and social service providers


Physicians are required by state law to report suspected cases of active TB to the county health department within one day. Do not wait for culture confirmation, which may take up to two months, to report the case. Delayed reporting may contribute to the development of multidrug resistance and to increased transmission of infection and disease if contact investigation is delayed.

A case does not need to be referred, simply reported. Quarterly status reports on each diseased patient must be furnished to the county TB control program. Positive results of TB skin test, QuantiFERON, or TSpot do not need to be reported.
