How old can the TB test be?
If a tuberculin (TB) skin test is required for you, the test must be less than 3 months old from the first day of classes at Mason. A tuberculin skin test, a quantiferon blood test, or a t-spot test will be accepted to meet the requirement.
If you have documentation of a previous positive TB test, only provide documentation of history and a chest x-ray report. A chest x-ray report must be less than 3 months old from the first day of classes at Mason. Provide documentation of medication if taken.
