Part III: TB SCREENING and IMMUNIZATION RECORD
Screening consists of a 2-step PPD test or an interferon gamma release assay blood test, such as QuantiFERON-TB Gold, within 6 months prior to the start of their first rotation. This requirement applies only to students who do not have a history of a positive PPD.
The two-step PPD consists of two PPD skin tests administered 1–3 weeks apart. PPD results must be reported in millimeters. If students choose an IGRA test, such as QuantiFERON-TB Gold, a single screening satisfies the TB requirements if the result is negative. Students with a history of BCG vaccination or anti-tuberculosis therapy are not excluded from this requirement.
If a student's QuantiFERON-TB Gold is positive, or if the student's PPD is >10mm currently or by history, the student does not need to repeat these tests. In this case, the following statement must be signed and dated by a physician and submitted with the official report of a recent chest X-ray. This must be done annually.
“I have been asked to evaluate [student name] because of a positive PPD (>10mm) or a positive QuantiFERON-TB Gold. Based upon the student’s history, my physical exam, and recent chest X-ray (date < 6 months), I certify that the student is free of active tuberculosis and poses no risk to patients.”
The exam and the chest X-ray should be completed within 6 months prior to the start of the first rotation.
