Three individual formalinized stool specimens from each of 123 patients were pooled and examined for ova and parasites. Results obtained from the pooled specimens were compared with those obtained with the three individual specimens used to make the pooled specimens. Of 123 sets examined, 92 were negative and 31 were positive for ova and parasites. The pooled specimens were positive and all individual specimens were negative eight times, whereas the pooled specimens were negative and the individual specimens were positive twice. The data indicated that the pooled system is a useful and economical method of screening for ova and parasites.
从123名患者中每人采集三份经福尔马林固定的粪便标本,将其合并后检查虫卵和寄生虫。将合并标本的检查结果与用于制备合并标本的三份单独标本的检查结果进行比较。在检查的123组标本中,92组虫卵和寄生虫检查呈阴性,31组呈阳性。合并标本呈阳性而所有单独标本均为阴性的情况出现了八次,而合并标本呈阴性而单独标本呈阳性的情况出现了两次。数据表明,合并标本检查系统是一种用于筛查虫卵和寄生虫的实用且经济的方法。
