一、直接涂片法（Direct Smear ）
二、饱和盐水浮卵法（Fecal Flotation）
Mix several grams (a teaspoonful) of feces with the flotation solution in a plastic cup.
Strain the mixture through a cuprum strainer (60 mesh) into another plastic cup.
Allow the flotation to stand for at least 5 minutes.
Take a few drops of the surface of the solution with cuprum wire loop on a microscope slide, examine them under the mecroscope with the 10× lens.
三、沉淀法（Fecal Sedimentation）
Mix about 100ml of water with about 10g of feces and place in a plastic cup.
Strain the mixture through a cuprum strainer (60 mesh) into another cup.
Allow mixture to sit for 10 minutes and then decant the supernatant.
Add more water, mix, and repeat the sedimentation procedure until the supernatant will be very clear.
Stir remaining mixture and place a few drops on a microscope slide, examine them under the mecroscope with the 10× lens.
