Routine LTBI testing (TST or IGRA) and treatment after exclusion of active TB:
- Are recommended for patients with silicosis, on dialysis or taking long-term immunosuppressive therapy.
- Can be considered for health staff, populations in congregate living settings (e.g. detained persons, refugees), migrants from countries with a high TB prevalence, homeless people and drug users.
LTBI testing should be performed periodically (e.g. once a year).
Routine LTBI testing and treatment is not recommended for patients with diabetes, maltutrition or chronic alcohol use, unless they belong to the above-mentioned risk groups.
