Criteria for diagnosis in pulmonary tuberculosis

ABSTRACT

In a retrospective study, case records of 1061 patients treated with antituberculosis drugs were examined to assess the criteria for diagnosis in each case. Seventy six percent had sputum examined for A.F.B. and 45% had mantoux test done. Five hundred and eighty one [55%] were diagnosed on radiology alone, while 262 [25%] had positive sputum for A.F.B. Only 50 [5%] of cases had positive Mantoux in addition to positive sputum and radiological changes. Practical significance of this practice is discussed
