Laboratory surveillance
According to the directives of the Taiwan Guidelines for TB
Diagnosis & Treatment , a basic laboratory survey, including
measurements of complete blood count with differential count, tests of
liver function (aspartate transaminase, alanine transaminase, and total
bilirubin), and tests of renal function (blood urea nitrogen,
creatinine, and uric acid), must be performed before initiating anti-TB
treatment and at 2, 4, and 8 weeks after initiating anti-TB treatment
[17]. Further laboratory surveys are allowed if the primary care
physician deems it to be necessary.
