成对的白天和夜晚的血液标本41人生活在埃塞俄比亚西南部的高流行性班氏丝虫病地区进行了检查微丝蚴核孔过滤器，厚膜，计数室技术。过滤技术非常敏感，通过过滤白天的血液而不是通过常规方法检查夜间的血液来确定更多的感染者。将过滤的血液体积从1 ml增加到5 ml，增加了当天鉴定的阳性数量。过滤5毫升白天的血液就不需要检查夜间的血液，即使很高比例的感染者的循环微丝蚴数量非常低。
Paired day and night blood specimens from 41 persons living in a hyperendemic Wuchereria bancrofti area of southwestern Ethiopia were examined for microfilariae by Nuclepore filter, thick film, and counting chamber techniques. Filtering techniques were so highly sensitive that more infected persons were identified by filtering day blood than by examining night blood by conventional methods. Increasing the volume of blood filtered from 1 ml to 5 ml increased the number of positives identified during the day. Filtering 5 ml of day blood obviated the need for examining night blood, even though a high proportion of infected persons had very low numbers of circulating microfilariae.
