Renewal visa but they found on my x-ray that i have ptb

Hi. I've been working for 9yrs here in abu dhabi. But today on my renewal of visa, my pro told me that there was a problem on my medical. They make me sign a form regarding the treatment for ptb and non compliance will cancel my recidency. After two weeks i recieved my passport and visa and they gave me a paper that says i will go for x-ray on july. That will be 3 months from my 1st medical exam. It has a note that says issue certificate and follow up, with all my info details. Then below it says
Final action for this case: Release the certificate, ensure that the patient is followed up in infectious diseases clinic after signing the consent form, Report non compliance to DOH/CDD.

What does it mean. Do i need to go to a clinic physician now before my scheduled x-ray which is 3 mo from now? Or should i just do the x-ray and wait for the result if they will be the one who will endorsed me to a physician? Because im wondering why a retake after 3 months? If i haven't got any treatment yet. Im really nervous. Anyone who had the same situation also for renewal but found ptb on x-ray. What was the process?
