I had it awhile ago. The GI's office, BCBS, and Prometheus are still hashing out the payment. The GI's office says they always get it covered, but it will take some time. In the event BCBS won't cover it, Prometheus says it will cost $250. All that information will be in the information packet and forms you fill out for the test.
You might not get a firm answer on coverage until after you take the test.
My results just added more gray to the mix. No antibodies, some Remicade in my system (@ 10mg/kg/6wks). I'm not willing to up the dose or add methotrexate or Imuran to the mix. Right now I've got a terrible rash going on, so I'm postponing (perhaps indefinitely) my infusion.
