Thanks I think that I may have to have that tested. I had that done a few weeks before the infusions started. I did not know about the 4 week test. Thanks!!!
There are 2 Prometheus Infliximab tests. One where they measure how much is left in your system after your infusion, the other that measures the antibodies. I think my doctor did both and it showed none of the medication left in my system, but enormous amounts of antibodies. At that point we had no choice but to take me off the meds.
I'm not sure what test you had before you started, maybe one that shows if your body will metabolize it correctly?
Make sure you do some research before you order the test, lots of doctors don't know anything about them.
