摘要
为评价(1-3)-β-D-葡聚糖检测(G试验)对侵袭性肺部真菌感染的诊断价值,对肺部感染患者130例行G试验,并将试验结果与病原学诊断结果相比较,计算G试验的灵敏度、特异性、阳性预测值、阴性预测值及准确性。结果表明:G试验对侵袭性肺部真菌感染的灵敏度为76.5%(13/17),特异性为80.7%(88/109),阳性预测值为38.2%(13/34),阴性预测值为95.7%(88/92),准确性为80.2%(101/126)。G试验是一项安全可靠的技术,对排除侵袭性肺部真菌感染有较高的价值,结合其它指标有可能提高诊断的准确性。
To evaluate the diagnostic value of plasma（1-3）-β-D-Glucan（G test） in patients with invasive pulmonary fungal infection.The plasma（1-3）-β-D-Glucan（G test） levels in 130 patients with lung infection were measured.The sensitivity,specificity,positive predictive value,negative predictive value and accuracy of G test were calculated.The results showed that the sensitivity,specificity,positive predictive values,negative predictive values and accuracy of G tests for invasive pulmonary fungal infection were 76.5%（13/17）,80.7%（88/109）,38.2%（13/34）,95.7%（88/92） and 80.2%（101/126）,respectively.G test may be safe and credible in excluding the diagnosis of invasive pulmonary fungal infection,but it needs other tests and indexes to increase the accuracy of diagnosis.
