Does Obtaining a Health Certificate Require Fasting?

Generally, it is necessary to be fasting when applying for a health certificate. Therefore, it is recommended to fast for 6 to 8 hours in advance to avoid affecting the test results. When applying for a health certificate, a physical examination is usually required, which mainly includes chest X-ray or CT examination, blood routine examination, liver function test, kidney function test, etc. Among them, the blood routine examination, liver function test and kidney function test usually require a fasting state. If you eat before the examination, the food may be digested and absorbed by the body, which will affect the biochemical indicators in the blood and make the test results inaccurate. Therefore, to ensure the accuracy of the test results, avoid eating before applying for a health certificate. In addition, avoid staying up late and drinking alcohol before applying for a health certificate to avoid adverse effects on your body.

After the test results are released, if there are no abnormalities or diseases, you can usually proceed with the application process normally. However, if there are abnormal test results and you have certain diseases, it may affect the normal progress of the application. In this case, you need to cooperate with the doctor for treatment before proceeding with the application.
