摘要: 本文观察了肺吸虫炭粒抗原用于诊断肺吸虫病的结果。抗原制备以10~12mg研磨、超声粉碎、浸渍的成虫全抗原致敏100mg活性炭的效果为最适宜。炭粒抗原的特异性较高。 对现症肺吸虫病人、正常人及其他疾病患者的血清作微量间接炭粒凝集试验的结果表明,以≥1:32作为诊断标准,对肺吸虫病的敏感性为100%,特异性为97.3%,而与正常人及其他疾病患者的交叉反应仅2.4%。 本法的敏感性不亚于酶联免疫吸附试验(100%)和间接血凝试验(96.9%),而高于对流免疫电泳(84.1%)和琼脂凝胶扩散试验(73.4%),对近期(2~7个月)疗效的考核尚欠理想,而对一年后的疗效考核可能有一定意义。

Abstract: A serological method for the diagnosis of paragonimiasis was introduced; The carbon antigen was prepared with carbon particles sensitized by sonicated Porogonimus antigen (100mg carbon: 10-12mg antigen). Sera of 64 patients of paragonimiasis were tested and all of them showed positive reactions (≥1:32), while 374 sera of normal human and other patients gave 2.4% false positive only. Four other serological test were run simultaneously with this method, the positive rate of ELISA and ICAT were 100% (64 cases), IHA 96.9%, CIE 84.1% and AGD was 73.4%. Thus the ICAT is a specific, sensitive, simple and rapid diagnostic tool for paragonimiasis.
