Tuberculosis (TB) Skin-Test Clinic

A skin test is used to screen for tuberculosis. Region of Waterloo Public Health's TB Skin Testing Clinic is held each Tuesday by appointment only.

Clinic Details:

  • The start time of the clinic varies week to week
  • The test is placed on Tuesday and read on the Thursday of the same week, at the same time. (E.g. 9:00am Tuesday test must return at 9:00am Thursday for reading)
  • The fee for a TB skin test is $12.00 unless it is required for medical investigation or treatment purposes
  • If a person has a documented positive TB skin test, the test will not be repeated
  • The TB skin test clinic only operates out of the Waterloo office at 99 Regina St. South
  • Please call 519-883-2272 to make an appointment.

Two-Step Test:

  • A two step test means that an initial test is placed and read (in the 48 hour timeframe) to establish a baseline.
  • If this initial test is positive no further testing is completed. If the test is negative, a second test is performed one to four weeks after the initial test and again read 48 hours later.
  • If a person has a documented two-step test, an additional two-step test never needs to be repeated.

Two-Step testing may be recommended for persons who:

  • Require subsequent testing e.g. health care workers, correctional workers
  • Are residents or staff of a long term care facility
  • Are from countries with high prevalence of Tuberculosis
  • Are undergoing medical investigation
