Diagnostic Criteria for Tuberculosis Disease

Definite diagnosis

  • Clinical picture consistent with tuberculosis; bacteriologic confirmation (culture, gene probe/NAA + AFB smear); histologic findings

Probable diagnosis

  • Clinical picture consistent with tuberculosis; exclusion of other diagnostic considerations; presence of highly specific tuberculosis (surrogate) marker

Likely diagnosis

  • Clinical picture consistent with tuberculosis; exclusion of other diagnostic considerations; typical response to antituberculosis treatment (in absence of other treatment)

NOTE. AFB, acid-fast bacilli; NAA, nucleic acid amplification.
