在粪检阳性率为74.4％的血吸虫病重流行区,如以环沉率≥1％为阳性反应,则免疫荧光环卵沉淀反应(IFCOP)和常规环卵沉淀反应(COP)与粪检阳性的符合率均在90％以上;环沉率≥6％者的符合率均为69.5％,无显著性差异。粪检阳性率为15.4％的轻流行区如以环沉率≥1％为阳性反应,则两种方法与粪检阳性的符合率分别为88.9％和6.7％,差异显著:环沉率≥5％者,分别为39.7％和41.3％。提示在轻流行区IFCOP对抗体水平低的患者,其敏感性要高于常规COP,并表明若以环沉率≥5％为阳性界限,两法均有相当多的病人被漏诊。
In the endemic area of schistosomiasis with a positive stool detection rate of 74.4%, immunofluorescence enucleated (IFCOP) and conventional circovirus (COP) and stool positive Of the coincidence rate of more than 90%; ring deposition rate ≥ 6% were 69.5% coincidence rate, no significant difference. If the prevalence of fecal seizures is 15.4%, the coincidence rates of the two methods with fecal seizures are 88.9% and 6.7%, respectively %, Respectively, 39.7% and 41.3%. These results suggest that the sensitivity of patients with low IFCOP antibody level in the light endemic area is higher than that of the conventional COP and that a considerable number of patients with both IFCOP and light COPD patients are missed if they are ≥ 5% positive.
