@anwar01....
In my country we require 4 passport photos for Medical per family member and for PCC 2 photos each (Myself and my wife)
So associated documents may really vary from one country to the other...please contact them or read on their associated site before going to make sure..however the passport(and several copies for each ) will be a common requirement for any country in the associated process
Also for me.... They didn't ask for any special requirement for the photos layout and didn't ask for fasting before analysis as its only investigate very specific abnormalities
