介绍了用抗ＥＣＡＭｃＡｂ双位点夹心ＥＬＩＳＡ法检测尿中肠杆菌科细胞共同抗原（ＥＣＡ）快速诊断尿路感染的临床研究。９６０份送检标本中，肠杆菌科细菌＞１０５ＣＦＵ／ｍｌ的２２３例，ＥＬＩＳＡＰ／Ｎ＞３．１的２２２例，２．２～３．１的１例；细菌在１０２～１０５间的８６例，Ｐ／Ｎ＞３．１的５０例，２．２～３．１的３２例，≤２．１的４例；有４例无菌生长尿液，Ｐ／Ｎ＞２．１，抗生素活性均阳性。结果表明，用免疫方法检测ＥＣＡ不受抗生素等干扰因素影响，有快速诊断尿路感染的价值。
A clinical study on the rapid diagnosis of urinary tract infection by Enterococcus faecalis common antigen (ECA) in urine by anti-ECAMcAb two-site sandwich ELISA was introduced. Of the 960 samples tested, 223 Enterobacteriaceae bacteria> 105 CFU / ml, 222 cases with ELISAP / N> 3.1, and 1 case from 2.2 to 3.1; 86 cases with 102 to 105 bacteria , P / N> 3.1 in 50 cases, 2.2 ~ 3.1 in 32 cases, ≤ 2.1 in 4 cases; 4 cases of sterile growth urine, P / N> 2.1, antibiotic activity Are positive. The results showed that immune method to detect ECA without antibiotics and other interference factors, the rapid diagnosis of urinary tract infection value.
