As I know they are not going to repeat the same medical examinations, unless they do have some doubts about some of your results, but some different examinasions about the condition of the whole body, so I think it might include alcohol (liver medical test) and drug (blood and/or urine medical tests)... but I do not remember any specific tests they send we are going to take, they just said more detailed examinations
Hope, I help a little
PS - of course, I think you can also asked them
