Abstract

Abstract:

All of 1717 sputum specimens from suspected tuberculosis patients in Shaanxi Tuberculosis Prevention and Control Institute were collected and stained with Ziehl-Neelsen staining method. First, Mycobacterium tuberculosis scanning system was used for microscopic examination, and then the same batch of specimens were examined by manual microscopy. Using sputum culture and detection of Mycobacterium tuberculosis as the standard, the positive detection rate of Mycobacterium tuberculosis scanning system and manual microscopy in the diagnosis of tuberculosis were compared. The positive detection rate of Mycobacterium tuberculosis scanning system and manual microscopy were 94.67% (231/244) and 59.02% (144/244), the difference was statistically significant (χ²=87.166, P=0.001). Compared with manual microscopy, Mycobacterium tuberculosis scanning system has higher positive detection rate, and higher application value in the diagnosis of tuberculosis.

Key words: Mycobacterium tuberculosis, Contrast sensitivity, Diagnostic techniques and procedures
