If it is a municipal hospital, all departments have relevant doctors and nurses on duty on Saturday and Sunday.
If the hospital you want to see is a private clinic or a small township hospital, ask in advance whether there is a doctor on duty during this period on Saturday and Sunday.
It's just that there are fewer staff on Saturdays and Sundays, and there are more people to see a doctor, so the waiting time may be longer than usual, whether it's laboratory tests or queuing for medical treatment.
