I had a liver ultrasound at LBO Clinic in Jungnang-gu, and the explanation was kind and helpful.

I visited the hospital because my liver enzyme levels were high.
I decided to visit because it is close to my workplace and I heard that they provide good medical care in Jungnang-gu.
There are also many people who get checkups on Saturdays and Sundays rather than weekdays.
It seemed like the waiting time was long because there were a lot of general patients.
I think the waiting time was longer because I was having a liver ultrasound. The doctor explained everything kindly and in detail while taking the ultrasound, so it was easy to understand. They mentioned that they start early on weekdays and suggested that it would be better to come on a weekday next time rather than on Saturday or Sunday.
There is a hospital close to my company, so it was convenient to get treated, and since it is a general hospital, I had a good visit.
