I was about an hour, they are very thorough, go through your past medical history (apparently it speeds things up if you take a letter from your doctor saying that you are fit for surgery, I have seen a few girls on here been messed about and stressed because the nurse has not heard back from their GP. They take your blood pressure, blood samples, and mrsa swabs from your nose and groin area, which is abit embarrasing when your nana is in the same room lol. They measure your height, way you, take before pics and run you through everything, don’t think that I have missed anything!! I hope that this helps xx
