I was told everything on the sheet which they ask for must be done. I spent a fortune but had my chest x rays, dentist report and x-rays, bloods all done and general medical along with all my vaccines.
They stated that they need the bloods done before you go as if you test positive you will not be issued a visa and the chest x ray is done to check TB as im guessing if they didn't do this people might lie and end up having to be sent home after they have paid all that money to fly them out.
My medicals took over a month to be approved even though I uploaded mine within 2 week.
Hope this helps
