[Evaluation of different methods of detection and diagnosis for infectious pulmonary tuberculosis]
Objective:
To evaluate the compare the efficiency and benefit of fluoroscopy and direct sputum examination.
Method:
The suspected persons with pulmonary tuberculosis symptoms were enrolled to be examined with fluoroscopy, chest radiography, sputum smear and culture.
Result:
The diagnostic procedure used by World Bank-loaned Tuberculosis Control Project in China is based on fluoroscopy screening. The miss-detection rates of smear positive, culture positive and bacteriological positive pulmonary tuberculosis were 10.5%, 28.3% and 28.2% respectively. Its accuracy of diagnosis was lower than that of direct sputum smear examination and the cost was higher.
Conclusion:
Direct sputum smear examination seems to be the best diagnostic method for infectious pulmonary tuberculosis and suitable for application in rural areas.
