Handling a health certificate is a prerequisite for food and other work to prevent the spread of infectious diseases. To a great extent, it protects the health of employees and customers. Time varies from place to place, and you can get a health certificate in about a week.
Before applying for a health certificate, you need to go to the physical examination department of the hospital for a comprehensive physical examination. Health certificates usually exclude infectious diseases, such as hepatitis B and tuberculosis. You can't eat any food or water in the morning because you need an empty stomach blood test. After eating, transaminase will increase, which will affect the test results.
