不同性状痰液标本直接涂片抗酸杆菌检出率的分析

目的:探讨痰液标本不同性状对抗酸杆菌检出率的影响。方法:将我院2006～2009年痰涂片结果进行回顾性分析。结果:8071份痰液抗酸杆菌阳性检出率为17.5%(1409/8071),4种不同性状的痰液(干酪样痰、血痰、脓粘痰、泡沫水样痰)抗酸杆菌阳性检出率分别为52.5%、42.4%、22.8%、3.2%,合格性状痰液标本(干酪样痰、血痰、脓粘痰)抗酸杆菌阳性检出率明显高于不合格痰液标本(泡沫水样痰)。结论:痰液标本性状直接影响抗酸杆菌阳性检出率,留取合格的痰液标本是提高抗酸杆菌直接涂片检出率的关键。

Direct Sputum Smear Different Traits Detection Rate of Acid-fast Bacilli

Objective:To discuss the difference positive rate of acid-fast bacilli on different traits of sputum samples.Methods:Retrospectively analyzing the results of the sputum smear in our hospital from 2006 to 2009.Results:The total positive rate of 8071 samples was 17.5%(1409/8071),Positive rate of four different types sputum(cheese-like sputum,bloody sputum,purulent phlegm,sputum water bubble) was 52.5%,42.4%,22.8%,3.2% separately.Positive rate of qualified traits sputum samples(cheese-like sputum,bloody sputum,pus,phlegm) was higher than unsatisfactory sputum(phlegm bubble water).Conclusion:Different traits of sputum samples directly affect positive rate of sputum smear,it is the key point to obtain the qualified sputum to improve the positive rate of sputum smear.
