I had my medical on Monday - it was a fairly straightforward process and there wasn't anything out of the ordinary.
The medical itself took only 20-30 minutes; however, the chest x-ray itself took 5 minutes and the blood was relatively quick! It's mainly waiting for the chest x-ray that add time as it was a walk in appointment (30-40 minutes in my case)!
The medical itself had a few elements to it. The first part involved the doctor going through my vaccination history records, filling in a worksheet that had each required vaccination, and the dates that I had that particular vaccination (the list of vaccinations is on the CDC's website). The only vaccination that I did not have was chickenpox (had this a child) and influenza (exempt at the moment because the 2019 vaccination isn't available yet/not flu season). For this, it definitely helps to have a detailed list of vaccinations and dates administered (most doctor practices have computer software that prints vaccinations completed at that practice in a nice and neat list for you).
We then went through a few questions about medical history. Some questions included: any illnesses/injuries that involved being hospitalized, any heart conditions/heart disease, am I a smoker, do I have asthma, do I have a history of stroke, do I have difficulties with learning/memory/speech, do I use recreational drugs or engage in substance abuse, have I tried to end my life, pregnancy, etc.?
A physical examination follows where we the doctor then examined my body (this involved touching the abdomen, skin, neck, etc.). Tests were also done on my lungs, blood pressure, heart rate, ears, height, weight, throat, teeth, and mouth. There was also a test on reflexes to check brain asymmetry (i.e. does my brain react to stimuli in the say way/degree on both sides of my body). The last part was an eye test to see how my vision faired by asking me to read the smallest line I could see.
After all this was done, it was a visit to the x-ray centre for a chest x-ray (to check for TB), followed by a visit to the pathology lab for a urine sample/blood test. Results are sent to the doctor, who then gives you a copy of the x-ray and completed vaccination worksheet. The medical itself is sent to the embassy and, unfortunately, you're not allowed to see it (I was told that there wasn't any issues with the examination, but we cannot get a copy of the form itself).
Hoping this helps anyone that's curious about the whole medical process!
