contact the medical centre and ask if the medical exam is the same. if it is you will hopefully be ok, however it may be good to speak with the embassy also to make them aware
I would say if anything there may be additional tests or immunisations, and hopefully the doctor would be happy to do these and add them on. Did you provide the paperwork to them or did they have it already? The reason I ask, is over here in NZ the embassy provides you with the paperwork which you must take to the doctor. There's no mention of a visa type, its just a "US immigration medical" here.
