Moreover, routine microscopy and culture are not sensitive
enough to detect active TB cases among people living
with HIV. A diagnostic algorithm for diagnosis and screening
of TB in HIV was developed by previous researchers in
Thailand. Combined use of a highly sensitive screening
algorithm as well as a rapid confirmatory diagnostic tool,
such as Xpert MTB/RIF, is necessary. Further, the setting
up of a diagnostic trial in Chiang Rai for early detection of
TB is mandatory
