I have had Crohn's over 30 years. 6 surgeries and multiple pcp's and gastro doctors. Now on Remicade for 3 years. I just changed gastro's because the one I had was very far away and really didn't appear to be the least bit interested in anything but the actual intestines. Like most people I have crohn's related issues. Vison, AS, joint problems etc. So very new Gastro is local and this is the first Remicade infusion with her. I called to see if she wanted blood tests prior to the infusion and no response.... last doctor also only took blood test yearly. What is usual? 8 week infusions- when should testing be done??
