Well, I don’t know much about Zhangdian. Many hospitals can do these three things, and you don’t need to go to a special hospital to do them. Those near the train station, such as Zhangdian District People's Hospital, Railway Hospital, and even Zibo Maternal and Child Health Hospital, can do it... (because I often pass by when buying books)
Electrocardiogram, chest X-ray and hepatitis B series They are all very common projects. The machines are all the same and the reagents are all used in China. The sensitivities are not much different. Basically, no special experience is required. You can check the same thing wherever you go. Unlike color ultrasound, the technical level of the doctor will have a greater impact on the examination results.
Well, the medical charges in Zibo City and Linzi District should be similar... Just for your reference. I had an internship at Linzi District People's Hospital, where the ECG is 30 yuan, the hepatitis B series is 50 yuan (approximately), and the chest X-ray is only 50 yuan (very few people do this anymore...). The ECG and chest X-ray results will be available immediately. For the hepatitis B series, blood will be drawn in the morning and the results will be available in the afternoon. Fasting is not required and will not affect the results.
