According to the inquiry, some doctors believe that it is not necessary to have an empty stomach to apply for a health certificate. Health certificates are mainly aimed at service personnel in catering industry, staff in water industry, medicine industry and beauty service industry. The examination items include stool culture, chest radiation examination and blood examination. Blood test does not check blood sugar and blood lipid, but mainly checks alanine aminotransferase.
With the update of modern detection equipment, alanine aminotransferase can be detected at any time without fasting.
