worm check method

The worm inspection method is an auxiliary inspection method for detecting parasites. Take all the feces from 24 to 72 hours after taking the medicine, stir with water, filter out the feces with 40 mesh copper sieve or gauze, rinse repeatedly with water, pour into large glassware filled with water, and lining the vessel with black paper. The worms mixed in the feces were detected for identification. This phase check can be used to determine the corresponding symptoms.
