Introduction
Generally, a health certificate requires fasting. When applying for a health certificate, certain biochemical tests—such as blood glucose, cholesterol, and liver function—are usually required. It is recommended to fast for 8–12 hours before the examination to minimize interference from food components on blood-related indicators, thereby ensuring the smooth completion of the medical check-up and the issuance of the health certificate.
Generally, a health certificate requires fasting to ensure the accuracy of test results. The detailed explanation is as follows:
When applying for a health certificate, certain biochemical tests—such as blood glucose, cholesterol, and liver function—are typically required. These tests must be performed on an empty stomach to ensure accurate results. Eating before the examination causes food to be digested and absorbed, which may affect the biochemical levels in the blood and lead to inaccurate test results. Generally, to ensure accuracy, it is recommended to fast for 8–12 hours prior to obtaining the health certificate.
It is advisable to maintain good sleep and dietary habits, stay relaxed, avoid staying up late, and bring all necessary identification documents on the day of the medical examination to prevent any impact on the test results.
