TB INTERFERON ANTIGEN (QuantiFERON-TB Gold) NLL Test# 99434.
The updated guidelines are now appearing all over the place eg PubMed,
For assistance in developing recommendations related to IGRA use, CDC convened a group of experts to review the scientific evidence and provide opinions regarding use of IGRAs. Data submitted to FDA, published reports, and expert opinion related to IGRAs were used in preparing these guidelines. Results of studies examining sensitivity, specificity, and agreement for IGRAs and TST vary with respect to which test is better. Although data on the accuracy of IGRAs and their ability to predict subsequent active tuberculosis are limited, to date, no major deficiencies have been reported in studies involving various populations.
Unlike most (if not all) other emerging 'biotechs' QuantiFERON is no longer just a 'good idea,' it has now gained official endorsement.
