Where do I need to have Health Check Certificate in Hong Kong to apply China Student Visa?

I am a permanent Hong Kong resident and am joining a Shanghai University. I went to the PRC consulate in Hong Kong to apply for student visa (X visa) however my application was not accepted as I did not have the health check certificate. I have with me the JW202 form (issued by the Ministry of education of the PRC) and the enrollment notice from the University. Can someone tell me where I can go (In Hong Kong) for health check? The PRC consulate could not (read, did not) particularly help. Alternatively, can I go to Shanghai on ordinary tourist visa and change it to student Visa (x visa) after arriving China?

Thank you in advance for your assistance in this.
