摘要
目的探讨痰标本质量对结核杆菌阳性检出率的影响。方法将痰液直接涂片，萋-尼氏抗酸染色检查结核杆菌。结果1895份痰液结核杆菌阳性检出率（20．95％）。4种不同性状的痰液（干酪痰、血痰、粘液痰、唾液）结核杆菌阳性检出率分别为62．34％、48．72％、18．46％、9．57％，差异有统计学意义（P〈0．01）；不同时间采集的痰液（晨痰、夜间痰、即时痰）阳性检出率分别为25．0％、19．74％、7．43％，差异有统计学意义（P〈0．01）；不同年龄段的人群（0～20岁、21—50岁、51～70岁、71岁以上）送检的痰液阳性检出率分别为16．53％、19．14％、20．97％、27．09％，差异有统计学意义（P〈0．01）；不同性别的人群（男、女）送检的痰液阳性检出率分别为20．22％、21．96％，差异无统计学意义（P〉0．05）；城市居民和农村居民送检的痰液阳性检出率分别为19．34％和21．55％，差异无统计学意义（P〉0．05）。结论痰标本的质量直接影响结核杆菌的阳性检出牢，留取合格的痰标本是提高结核杆菌阳性检出率的关键。
Objective To investigate the influence to the positive rate of tubercle bacillus. Methods Direct smear of sputum was conducted with Ziohl - Neeisen acid - fast staining to detect tubercle bacillus. Results The detected rate of thel 895 sputum samples was （20. 95% ）. The positive rate of tyroid sputum, blood sputum,mucous sputum and saliva was 62.34% ,48.72%, 18.46% and 9.57 % respectively. There was a difference of them （P 〈 0.01 ）. The positive rate of the sputum collected in the morning,evening and on - the - spot was 25.0% , 19.74% and 7.43% respectively. There was a difference （P 〈0.01 ） 1 The positive rate from the persons at the age from 0 - 20,21 - 50,51 - 70 and the persons over 7 lyears old was 16.53% , 19.14% ,20.97% and 27.09% respectively. There was a difference （ P 〈 0.01 ）. The positive rate of the sputum from male and female was 20.22% and 21.96%, there was no difference （ P 〉 0.05 ）. The positive rate of the sputum from urban people and people living in the country was 19.34% and 21.55% respectively. There was no difference （ P 〉 0.05 ）. Conclusion The positive rate was directly affected by the collection of the sputum samplesl The key of the detected rate was to collect qualified sputum samples.
