Is it reliable for the company to arrange a medical examination in the United States? Do I need to go to the hospital for another check-up after I finish?

My personal feeling is quite reliable. If you are really not at ease, you can go to the hospital for re-examination. It's my first time to go to the United States for a big health, and I took my dad for a physical examination. At that time, B-ultrasound showed fatty liver, so I went to the hospital for reexamination. Indeed, the liver index is not very good. This year's physical examination showed a positive breath test, so I didn't check it again. I went directly to the gastroenterology department for consultation, and the doctor gave me medicine after reading the physical examination report.
