操作步骤: 1.作一蚕豆大小的棉在球,放於5％匹拉米董酒精溶液中,浸透後再放於一块洁净的戟物片上。 2.滴加冰醋酸及过氧化氢各2-3滴於棉球上。 3.用竹(?)排粪便一小块(约黄豆大)涂在棉花球上并稍加压力,使粪便与棉花球及试药液紧密接触。检视结果: 因为棉花本身是非常洁白的,如含有隐血粪便,使接触的棉花表面即呈浓烟色,瞬即变为蓝色,并随著纤维的毛细管现象向深层及四面扩散,很容易观察。 Steps: 1. For a bean-sized cotton ball, place it in a 5% palamid alcohol solution and then soak it in a clean tablet. 2. Add 2-3 drops of glacial acetic acid and hydrogen peroxide to the cotton balls. 3. Use bamboo (?) to excrete a small piece of manure (approximately large soybeans) on the cotton ball and apply a little pressure so that the stool is in close contact with the cotton ball and the test solution. Viewing results: Because the cotton itself is very white, if it contains occult blood, the surface of the exposed cotton will have a dense smoke color. It will turn blue immediately and spread to the deep and four sides with the capillary phenomenon of the fiber. It is easy to observe. .
