if it is the panel physician you don't need to upload anything as when you get the remedical req. you give the form that you download from gckey to the physician's office, they upload the results all by themselves, it would be helpful to provide the previous medical examination's receipt if you're going to the same physician, but incase if it is not the panel physician then you do need to upload the documents provided by the physician.I have a question
When remedicals are done, do we need to upload anything on the online account?
if you want to be absolutely certain about this just raise a normal webform and upload the receipt from the physician after getting the medical done.
Hope this helps.
