Objective To evaluate the influences of bacterial infections on the (1,3)-β-D-glucan detection.Method Serums of forty patients with identification of positive blood culture and forty patients with identification of negative blood culture,af-ter controlling disturbance,were detected by G tests.Results Among 22 patients with Gram positive bactereamia and 18 pa-tients with Gram negative bactereamia,only one patient identified as Escherichia coli infection was positive for G test,while four patients were G test suspicious and the rest were negative.Among 40 patients with negative blood culture,three patients were known as G test suspicious while the rest were negative.There is no statistic significance of G test results between speci-mens with blood culture positive and negative (P >0.05).Conclusion Bacterial infections have minor influences on G test de-tection in this study.%目的：探讨血液细菌感染对血清(1,3)-β-D-葡聚糖检测结果的影响。方法排除影响 G 试验结果的干扰因素后,选取符合入组条件的血培养细菌阳性及血培养阴性患者各40例,采集血清进行 G 试验检测。结果40例血培养细菌阳性标本中革兰阳性菌22例,革兰阴性菌18例,其中只有1例大肠埃希菌的 G 试验结果为阳性,4例在灰区,其余为阴性。40例血培养阴性标本3例 G 试验结果在灰区,其余为阴性。血培养细菌阳性组与血培养阴性组 G 试验结果差异无统计学意义(P >0.05)。结论血液细菌感染对 G 试验检测干扰较小。
