Z-visa physical examination requirements

I have a physical examination form filled by my doctor saying i am fit and healthy to enter China, I will be teaching English in the Jiangsu province, does anybody know if the chest x ray and Blood test is compulsory because in Great Britain they cost £300 which is a lot of money. But on this website it states that the Chinese employers will do another physical examination when I arrive in PRC, so is it possible to obtain the Z-type and work permit without a chest xray , blood test and electrocardiogram
When i enter PRC, could I get the tests done in PRC possibly?
