I did my medicals on 28th of August in Fortis, Bangalore. All they required for me was to carry my original passport and 2 copies of them. Along wit that, They do require your passport size photo and I guess thats it. The whole process was pretty quick, and was done within an hour. They took 4300rs approx, and didn't have to do any additional tests other than Xray, Blood and urine test, and Physical examination.
I hope this helps.
