Importance of KHADAMAT (Medical Test in India) before going to Kuwait

Dear All,
I received my VISA and did medical test today in KHADAMAT, India. I would like to know before going to Kuwait, what is the importance of these medical reports?
What if there is a UNFIT on my medical reports?
Do I have to do medical tests once again?

If there is an UNFIT, you will not be be allowed to work in Kuwait. It's as simple as that. You will have to repeat the medical test in Kuwait anyway.
