Tuberculin Skin Testing

What is Tuberculin Skin Testing? 

The Mantoux tuberculin skin test (TST) is a method of determining whether a person is infected with Mycobacerium tuberculosis. 

How is the TST administered? 

A TST is performed by injecting 0.1ml of tuberculin purified protein derivative jus under the skin of the forearm.  

How is the TST read? 

A TST reaction should be read between 48 and 72 hours after administration. If it is not read within 72 hours, another test should be scheduled. 

Tuberculin Skin Testing is available Monday through Wednesday from 8:00am-4:00pm. Call (608) 297-3135 to schedule your appointment.  

Tuberculin Skin Testing is $20 per test and $40 for a two-step test.
