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]768份痰液结核杆菌阳性检出率(12.24%)偏低。4种不同性状的痰液(干酪痰、血痰、黏液痰、唾液)结核杆菌阳性检出率分别为20.00%、0,13.76%、6.06%,差异有统计学意义(P<0.05);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14.04%、12.38%、3.92%,差异有统计学意义(P<0.05);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4.08%、6.67%、2.14%、9.80%,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12.82%、10.81%,差异无统计学意义(P>0.05);不同职业的人群(农民、工人、机关事业单位人员、学生)送检的痰液阳性检出率分别为11.97%、17.39%、13.33%、12.63%,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率,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 Ziehl-Neelsen acid-fast staining to detect tubercle bacillus, [Results]The detected rate of the 768 sputum samples was lower （12.24%）. The positive rate of tyroid sputum, blood sputum, mucous sputum and saliva was 20.00%, 0, 13.76% and 6.06% respectively. There was a difference of them （P〈0.05）. The positive rate of the sputum collected in the morning, evening and on-the-spot was 14.04%, 12.38% and 3. 920/oo respectively. There was a difference （ P 〈0.05）. The positive rate from the persons at the age from 0-20, 21-50, 51-70 and the persons over 71 years old was 4.08%, 6.67% ,2.14% and 9.80% respectively . There was a difference （P〈0.01）. The positive rate of the sputum from male and female was 12.82% and 10.81%, there was no difference （ P〈0.01）. The positive rate of the sputum from peasants, workers, persons working in government departments or institutions and students was 1l. 97% 17.39%, 13.33% and 12.63 % respectively. There was no difference （ P〉0.05）. [Conclusion]The positive rate was directly affected by the collection of the sputum samples. The key of the detected rate was to collect qualified sputum samples.
