以往非淋球菌尿道炎(NGU)的最初诊断多采用将病人的尿道涂片经革兰染色镜检及双杯尿试验,但这两种方法均存在着主观、不敏感及时间长的缺点。另外,脓尿症是尿道炎的一个敏感的指标,而大多数检查脓尿的新技术也费时较长且价格昂贵。最近介绍检测尿中白细胞酯酶活性的纸条试验对于检测脓尿症及筛查 NGU 病人都是十分理想的。因为白细胞酯酶为多形核白细胞(PMN)所特有,其活力与 PMN 计数密切相关。试验时用一塑料带一端固定有一含吲哚酚羧酸酯滤纸条,将其
In the past, the first diagnosis of non-gonococcal urethritis (NGU) mostly used the urethra smear of the patient with Gram-positive microscopy and double-cup urine test. However, both methods have subjective, insensitive and long-term disadvantages. In addition, pyuria is a sensitive indicator of urethritis, and most of the new techniques for checking pyuria are also time-consuming and expensive. The recent introduction of test strips for detecting leukocyte esterase activity in urine is ideal for detecting pyuria and for screening NGU patients. Because leukocyte esterase is characteristic of polymorphonuclear leukocytes (PMNs), its vitality is closely related to PMN counts. Test with a plastic strip with one end attached to a containing indoxyl carboxylate filter paper, will it
