Back in 2007 the HIV Clinic from the University of Nebraska Medical Center reviewed the
clinical utility of IGRA and found that
in summary, the ELISA-IGRA is a new assay based on in vitro detection of IFN-y that may replace PPD as a diagnostic tool for latent and active tuberculosis. The test is more specific and does not require patients to return for a second visit (as TST demands). Cost, technical limitations, and limited data in the most vulnerable groups, such as children and immuno suppressed patients, may prevent the immediate replacement of the TST.
The University of Nebraska did
advise that international students were required to have a
PPD (tuberculosis) skin test obtained at the University Health Center TB skin test
Required of all international students - NO EXCEPTIONS
Then in late 2009
it became
International students must have a test for tuberculosis at the UHC
Now they are asking students to fill in the
TB QuantIFERON Screening Questionnaire
