They do not give you the medical results, the results are sent to the embassy towards the end of the sponsorship process. My Husband did his medical about a week before I returned to Canada, and I brought the documentation with me to send with the application.
On Ecas it showed medicals received just before he was issued his visa. He had passed his interview and was told he was approved about 2 months before he received the visa. I have heard that the embassy requests the medical result once they have approved the applicant.
When the person is approved it usually says "Medical received, decision made" on Ecas. when it is a refusal it just says decision made, there is no mention of the medical.
I personaly took a medical exam here to present that stated that I was in good health, and had no communicable diseases.
Good luck
