Can I get a health certificate only in the morning?

No, you can handle it during normal working hours. The health certificate can be processed not only in the morning, but also during normal working hours, just by fasting. It is also mentioned that some examinations need an empty stomach, but if these examinations are over, the rest of the physical examination and chest radiograph will be done in the afternoon, and you can eat normally at noon, which will not affect the results of the physical examination. Therefore, it is suggested that it is better to go to the physical examination center or the hospital outpatient service on an empty stomach in the morning.
