So today I got my results back from my blood test a few weeks ago. When I got this blood test, it was two days before my Remicade infusion. My doctor and I were suspecting that my levels of Remicade were starting to get low around week 6 since that is when some of my symptoms start to reappear (I discussed some of this in a post from a few days ago). I have noticed this pattern for the last three infusions. Currently, I am on the 8 week cycle of the standard dosage of Remicade. I am just confused since my symptoms reappear around week 6 but my levels are adequate and I have no antibodies. My doctor did decide to discontinue 6mp back in February, but I don't think that has necessarily been the issue. Any thoughts?
