Stop using IGRA to test for active pulmonary TB!
this keeps coming up, so I summarized my take-home messages on this (with a link to the BlueSky discussion)
in hospitals that lack deep experience with TB, I think the best heuristic is simply not to use an IGRA to look for active pulmonary TB

TB gurus: is there a role for using interferon gamma release assays to diagnose active TB?
guidelines & textbooks *don’t* generally recommend this (eg https://www.tandfonline.com/doi/full/10.1080/24745332.2022.2035638#appendixes)
but in practice I see this done a *lot* 🧐
