My wife has to have routine blood tests every month, and up until lately we have been able to stretch them out a bit if necessary to suit our travel plans. However the NHS has decided to upgrade her specialist biological drugs which means that the routine Blood tests now have to be very regular, every 28 days without fail! So here's the question "has anybody had to have Blood tests in Europe (after Brexit) under the GHIC system? and if so how does it work? Are Phlebotomy appointments easy to make? or must they be booked weeks in advance?
