How Should I Get Tested for TB?

Public Health Madison & Dane County (PHMDC) does not provide TB screening for work, school or volunteering. However, if you have other risk factors for TB, you may qualify for TB screening through PHMDC. PHMDC screens clients for TB with TB blood tests called Interferon Gamma Release Assays (IGRAs). T-Spot and QFT are two types of this TB blood test that PHMDC uses for TB screening. To get an IGRA test, call Public Health Madison & Dane County at: (608) 266-4821.

  • A receptionist will screen you for TB screening eligibility. If eligible, the receptionist will schedule an appointment with you.
  • At your appointment, you will fill out paperwork and have your blood drawn.

Lab test results will be sent to you in the mail typically within 1-2 weeks.

If you need a TB test quickly, you may want to get a TB test at one of the following Concentra locations:

  • 1619 N. Stoughton Rd., Madison, (608) 244-1213
  • 358 Junction Rd., Madison, (608) 829-1888

Call them for hours and cost.

Immunizations and TB

Can I have TB testing if I need vaccines too?

Certain live virus vaccines might affect TB test results. If you need TB testing and live virus vaccines (MMR, Varicella, FluMist nasal spray, yellow fever), choose one of the following two options:

  • Get the TB test either before or on the same day as the live virus vaccine(s).
  • Get the live virus vaccine(s) first. Then wait 4-6 weeks after the administration of the live virus vaccine to get the TB test.
