This happened to me too. When I did my medical exam, my BP was about 145/85 so the med tech made me rest for about 15 minutes and took the pressure again. It was still high so he gave me a sheet to be filled by a doctor. To have this filled, I had to give a blood and urine sample and get my BP measured each week (by a nurse) and then I had to get a blood pressure meter because the doctor thought I had white coat syndrome.
It turns out that by pressure is much lower when taken at home, around 120/60. So the doctor filled the sheet saying I have no health problem at all.
It's been long and complicated but I suppose they don't take chances and want everything checked.
Now, It's the 4th week I'm waiting for Borden to clear me. I hope for the best...
