When you apply for a health certificate, check the stool routine. The general laboratory will send a plastic specimen box and a stool spoon. Usually you only need to take a finger-sized specimen for examination when defecating. If you feel uncomfortable during the examination, you can also take the specimen the next morning.
Before the examination, carry out as usual according to the original living habits and eating habits, and be careful not to eat and drink. 2. Take feces with bamboo sticks or sawdust, the size of broad beans, put the feces into a box as a sample, write your name, and then send it for inspection immediately. The inspection time generally does not exceed two hours. 3. If there is purulent blood in the feces, take the purulent blood.
