Hi Sarah,
Yes, we do IGRA surveillance for mycobacteriologists every 6 months. This was one of the few areas where we continued surveillance after sunsetting most annual IGRA surveillance. When we tested most HCP annually, we tested this laboratory
group more frequently. However we have not seen any occupational conversions among this group despite them handling MTB cultures!

Good morning,
If your hospital microbiology laboratory performs
mycobacterial cultures in-house, does your institution conduct annual medical surveillance with TST or IGRA for
Mycobacterium tuberculosis (MTB) for laboratory personnel working in the BSL-3?
Thanks,
