The main purpose is to check whether there are infectious diseases!
To check liver function and hepatitis B, we should draw blood, send stool to check intestinal bacteria, and check the heart and liver through doctor's auscultation, palpation and visual inspection. What kind of heart disease do you have? If it is mild, most doctors will let it go.
In short, it should be no problem! But you must pay attention to rest when doing business.
I wish you the best of health! Business is booming!
