Tuberculosis Screening

All new employees, students and volunteers must undergo tuberculosis (TB) screening to join the Jefferson community. The standard TB screening for anyone entering the organization is an Interferon-Gamma Release Assay (IGRA) blood test. A chest X-ray is required of new employees, students and volunteers with a history of a positive skin test or positive IGRA. Skin testing is not performed on those with a history of a past reaction.

Annual Mandatory TB Screening Requirement: How to Become Compliant

There are three ways to become compliant with the annual TB screening requirement:

  1. Have an IGRA performed in OHN or at your physician's office with a copy to UHS
  2. Have a tuberculin skin test (PPD) placed and read in OHN or at your physician's office with documentation to OHN
  3. For those with a positive history of a positive skin test, positive IGRA or treated active TB, complete the bottom half of the UHS Mandatory Tuberculosis Screen form

Department Monthly PPD Compliance Listing

Due to a national shortage of PPD solution in 2013, mandatory testing was suspended until January 2014. At that time, HR and UHS announced that mandatory testing was reinstituted with prioritization of physician and nursing staff. The announcement included information that departments were being moved to a monthly schedule of testing to facilitate compliance tracking.

As departments move to the monthly schedule, some employees may get an "early" skin test. There is no harm, and an early PPD will not cause a positive reaction. Compliance within departments is expected by the end of their designated month.

OHN Hours

TB screening is done in OHN on a walk-in basis during the hours of 7:30 a.m. and 4 p.m. PPDs must be read within 48 to 72 hours.

Trained Providers

OHN has trained nurses who may place and read PPDs within their own units/departments. Documentation of the PPD is done on the UHS Mandatory Tuberculosis Screen form. The forms must be LEGIBLE, COMPLETE and may be scanned and emailed to
