I had to get a blood test to check if I had a blood condition which would affect me being able to have surgery or not. It cost about £28 but was necessary as my medical records did not state if I had it or not.
I believe that if u have a history of breast cancer or heart issues additional tests or medical records that are upto date need to be submitted.
Your Pc/nurse will make u aware of all this by the time ur medical checkup with the nurse happens because that’s when the tests are taken. I had my test four weeks prior to my op so if there were any issues (MRSA, I was concerned about as I work with children and teens) I would have time to sort it out
Hope that helps
