摘要
塑料管COPT诊断法,(塑管法)即将血清采集、血清分离及抗原血清孵育三步合成一步在管内完成,两大滴血清虫卵悬液只需几个视野即观察完毕。使用本法诊断血吸虫病441例粪阳者的阳性反应,90.9％;常规法89.8％;615例居民现场普查,两法分别为38.2％、39.2％,均无统计学差异。在轻重疫区,其现场检出率与常规法比较,亦无差异。本法具省工省时,节约器材等优点,适用于基层普查。
A modified technique of circumoval precipitin test for diagnosis of schistoso-miasis japonica by using polyethylene capilla ries instead of test tubes for blood collection and slides for ova incubation was introdeced.
Of 441 blood samples from schistosomiasis patients 401 were positive (90.9%) by the modified technique, and of 89.8% (396/441) by the classical procedure. 377 samples were positive and 21 were negative by both techniques.
In an epidemiological survey, 614 blood samples from inhabitants of production brigades with different levels of prevalence were tested simultaneously by both modified and classical techniques, 238 positive samples were detected by the former, while 242 by the latter.
It is suggested that the modified polyethylene capillary technique is much cheaper, more time-saving, and as effective as the classical method for large scale diagnosis in epidemiological survey of schistosomiasis japonica.
