REGARDING HEPATITIS B INFO required for employment in OMAN

Can Anyone brief immediately the various types of VISAS in OMAN for employment and whether all VISA need do blood tests for Hepatitis B, I request an urgent reply since I have to reply whether I am ready to take the offer or not. Be kind and give me the maximum details.

Don't go there because they deported me just 2 months before and my DNA PCR was negative but only HBSage screening was positive.
My LFT report was normall and I submitted doctor sertificate also in that certificate doctor clearly mentioned this person doesn;t required any treatment because his DNA PCR is negative and LFT is normal but Ministry of health was very strict they forcely sent me out of Oman. Please tell me about this in UAE and I will wait for your reply to me.
I am an Architectural Technician and worked 10 years in Oman just went for visa renewl.
