目的探讨肺结核患者痰标本质量对结核分枝杆菌检出的影响。方法采用痰涂片-抗酸染色法和用BASO公司L-J培养基进行培养,统计肺结核患者合格和不合格痰标本阳性检出率。结果肺结核患者合格痰标本涂片和培养的阳性率均显著高于不合格痰的涂片、培养的阳性率。结论肺结核患者痰标本质量是提高痰涂片和培养阳性率的最重要因素。
Objective To investigate the effect of sputum specimen quality on the detection of Mycobacterium tuberculosis in patients with pulmonary tuberculosis. Methods Sputum smear - acid-fast staining method and BASO L-J medium were used for culture. The positive rate of positive and negative sputum samples in patients with pulmonary tuberculosis was calculated. Results The positive rates of smear and culture of qualified sputum specimens of tuberculosis patients were significantly higher than those of sputum smear and culture without positive results. Conclusions The quality of sputum samples from patients with pulmonary tuberculosis is the most important factor to improve the positive rate of sputum smear and culture.
