The Legionella Urinary Antigen EIA kit (Binax, Portland, Maine) was compared with the EQUATE RIA Legionella Urinary Antigen kit (Binax) for its ability to detect the presence of urinary antigens to Legionella pneumophila serogroup 1. Urine specimens from patients without Legionnaires' disease (n = 33) were negative by both methods (specificity, 100%). Twenty (77%) of 26 urine specimens from patients with Legionnaires' disease positive by the radioimmunoassay kit were also positive by the enzyme immunoassay (EIA) kit. If the cutoff for a positive EIA result were lowered to a ration of > or = 2.5, 23 of 26 (88%) urine specimens would have been positive by EIA and the specificity would remain 100%. Use of the EIA kit is an acceptable method for detecting L. pneumophila serogroup 1 urinary antigens by laboratories that do not want to handle radioactive materials.
将军团菌尿抗原酶免疫分析试剂盒(Binax,缅因州波特兰)与EQUATE放射免疫分析军团菌尿抗原试剂盒(Binax)检测嗜肺军团菌血清1型尿抗原的能力进行了比较。来自非军团病患者的尿液标本(n = 33)两种方法检测结果均为阴性(特异性为100%)。放射免疫分析试剂盒检测为阳性的26例军团病患者尿液标本中,20例(77%)酶免疫分析(EIA)试剂盒检测也呈阳性。如果将EIA阳性结果的临界值降至≥2.5,则26例尿液标本中有23例(88%)EIA检测呈阳性,且特异性仍为100%。对于不想处理放射性物质的实验室,使用EIA试剂盒是检测嗜肺军团菌血清1型尿抗原的一种可接受方法。
