You may not qualify if:

  • Prior PPD test within the past 30 days
  • Subject is of childbearing potential and unable to use contraceptives; is planning pregnancy; is pregnant or lactating
  • History of anaphylactic reaction, severe positive tuberculin reaction (eg, ulceration, necrosis) or other severe reaction to PPD in the past
  • Subject received a Bacillus Calmette-Guérin (BCG) vaccination in the past, or was born or lived outside the US as a child and is uncertain of his/her BCG vaccination status
