What should I do if I have eaten when applying for a health certificate?

If you have eaten before applying for a health certificate, you usually need to wait until another day for the check-up, because eating may affect the accuracy of the test results.

Some of the physical examination items in the health certificate application must be done on an empty stomach. Generally, you need to fast for more than 8 hours, and the diet the day before should be light and digestible. You are not allowed to drink water before the physical examination. After eating or drinking water, it may affect the accuracy of the test results. Generally, the test cannot be done. It is necessary to choose another day to do the test, which will facilitate accurate test results and clearly diagnose whether there are some diseases in the body.

The physical examination items for applying for a health certificate include liver function test, blood lipid and blood sugar test. Liver function test generally requires blood test. After eating, the concentration of blood will be higher, and the liver function pathology cannot be quickly checked, and the blood sugar level will also increase.

People who are engaged in some manufacturing industries, such as food production and processing, or opening restaurants, kindergartens, etc., need to apply for a health certificate and ensure that they are in good health before they can engage in these industries. If the test results show that you have some liver diseases, such as hepatitis B, hepatitis A or hepatitis C, you generally cannot apply for a health certificate, otherwise it is easy to cause cross infection while working in these industries.
