All paid and unpaid HCWs (as defined in the "CDC Guidelines") must receive serial TB screening based on the facility’s risk level: (1) low risk - not needed; (2) medium risk - yearly; (3) potential ongoing transmission – consult the Minnesota Department of Health’s TB Prevention and Control Program at 651-201-5414.
Minnesota Rule 4655.4700
All residents must receive baseline TB screening within 72 hours of admission or within 3 months prior to admission. TB screening must include a written assessment of the resident’s risk factors for TB and any current TB symptoms,and a two-step TST or a single interferon gamma release assay (IGRA) for M. tuberculosis (e.g., QuantiFERON ® TB Gold or TB-Gold InTube, T-SPOT ® .TB)
This is a big change from the original laws here and here which clearly state that the TB skin test shall be used.
