Tuberculosis Testing Contraindications

If the Student Health and Wellness Center administers a PPD (TB skin test), you must return in 48-72 hours to have the skin test read to determine the results of the test. If you are unable to return at these specific times, you should not have the test done.

Do not have TB test done if:

  • You have had a positive TB test (significant reaction) in the past. Please tell the nurse.
  • You have ever taken TB drugs for a positive TB skin test in the past.
  • You have been diagnosed and treated for TB in the past.
  • You have a current fever with a temperature of >100 or a current viral infection - (defer skin testing for 4 weeks) and check with a physician if needed.
  • You are pregnant and haven't checked with your doctor.
  • You have received a Measles-Mumps-Rubella immunization in the past month.
  • You have a current skin irritation on your forearms or rash on your body.
  • You are currently taking any corticosteroids or immunosuppressive drugs, (such as Prednisone) and haven't received your doctor's permission to get a TB test. (The use of inhalers containing cortisone or other similar medications does not interfere with the TB skin test.)
  • You have any disease affecting your lymphatic system, (Hodgkin's, Lymphoma, Leukemia, etc.) and haven't received your doctor's permission to take the test.


  • If the PPD is read as significant, the nurse will talk to you about the need for a chest x-ray and follow-up.
  • Tuberculin skin testing in not contraindicated for persons who have been vaccinated with BCG. Please let the nurse know if you had the BCG vaccination and when.
