1110份痰标本直接涂片检查抗酸杆菌结果分析

Analysis of acid-fast bacillus inspection results of 1110 directly-smeared phlegm specimen

目的探讨不同性状的痰液涂片抗酸杆菌检出率情况。方法直接涂片萋—尼氏抗酸染色,将该中心结核病防治门诊2009年初诊及复诊的肺结核病人送检标本进行分析。结果各类痰液抗酸杆菌阳性检出率差别较大,其中最高A痰为77.2%,其次B痰为25.4%,再次C痰为14.1%,而D痰只有2.81%;4类痰液的阳性检出率之间有非常显著性差异(P<0.01)。结论不同性状的痰标本与抗酸杆菌的检出率有很大的关系,重视痰标本的质量,减少误检、漏检等方面不必要的失误。

Objective To explore acid - fast bacillus detection rate of phlegm specimen with different character. Methods Directly smear qi Nepal acid resistance dyes and carry out analysis of first diagnosed and subsequent determined pulmonary tuberculosis specimen delivered in 2009 at tuberculosis prevention outpatient service. Results The positive acid - fast bacillus detection rate of phlegm specimen varies a lot, among which type A phlegm is the high- est 77.2%, type B is 25.4%, type C 14.1% and type D only 2.81% ; the positive detection rates of these four types show obvious differences （P 〈 0.01 ）. Conclusion In consideration of relations between phlegm specimen wih different character and acid - fast bacillus detection rate, we should attach great importance to phlegm specimen, avoid unnecessary mistakes such as error- detecting and detection failures.
