使用漂浮集卵法(浮集法)检查粪内华支睾吸虫卵,虽然国内、外曾有试用报告,但由于检出率低等缺点,终未被广泛采用。1975年,我所首次使用70％碘化钾溶液静置浮集法检查粪内华支睾吸虫卵获得成功,并认为该法具有操作简单、检出率高等优点。惟所用化学试剂(碘化钾)价格较贵,因而其应用范围受到限制。为了求得改进,我们进行了以下几个方面的 Although the test report of fecal Clonorchis sinensis was used to detect the fecal Clonorchis sinensis eggs by using the floating egg collection method (floating method), it has not been widely adopted because of the low detection rate. In 1975, for the first time, we used the 70% potassium iodide solution standing float method to check the fecal egg of fecal Clonorchis sinensis, and found that the method has the advantages of simple operation and high detection rate. However, the chemicals used (potassium iodide) are more expensive and therefore have limited application. In order to make improvements, we conducted the following aspects
