My insurance company doesn't cover calprotectin, so it's been $250 out of pocket for me each time. I tried appealing the insurance company but it was denied because "calprotectin is experimental." I found a lab in Chicago that does the test by mail order for $125 but the doctor has to sign up with the lab. My doctor is contracted with his employer not to sign up with any (non employer) labs. He would give me a requisition in hand, or be happy to fax the requisition to any lab but that's not good enough for this lab. Does anyone have any advice?
