The efficiency of the polycarbamate membrane filtration technique for detecting Schistosoma haematobium eggs in urine has been increased by using a pore size of 14 micrometers diameter and the suction of a water jet pump. The technique permits filtration of several 1000 ml of urine in one test. Eggs concentrations of 1 egg in more than 1000 ml of urine were detected. Viability was assess after filtration by staining with trypan blue. Preliminary data of 118 Schistosoma haematobium-positive urine samples of 32 patients suggest that the filtration trypan blue-staining-technique is of high validity in light infection with scanty egg-output.
通过使用直径为14微米的孔径和水喷射泵抽吸，聚氨基甲酸酯膜过滤技术检测尿中埃及血吸虫卵的效率得到了提高。该技术允许在一次检测中过滤数千毫升尿液。检测到每1000多毫升尿液中含1个虫卵的虫卵浓度。过滤后通过台盼蓝染色评估虫卵活力。对32例患者的118份埃及血吸虫阳性尿样的初步数据表明，过滤台盼蓝染色技术在轻度感染且虫卵排出量少的情况下具有很高的有效性。
