When I came, from Australia, I downloaded and printed the Health Check form, which I got from the Embassy website, and took it to my own doctor, who did all the necessary, sent me to get the required X-rays, blood tests, etc.
I then sent this to my college in China, and this was needed for them to get me the approval to invite me to their college, and to get the necessary paperwork for me to get a Z Visa.
When I went to the Embassy, to get my visa, they also needed a copy of the Health Check form.
But, still, when I got here, I still needed to go to the local clinic, to have most of the tests done again. But the college took care of that, all it cost me was my time.
Hope this helps you.
