I used the same lab, but I didn't have to order it myself, yet the bill for the testing went to me instead of the ortho's office. The orthopedist ordered the metal and bone cement kit for me which was sent to his office, and they did the blood draw and sent the blood off to the Chicago lab. As I mentioned the results showed I was allergic to 5 metals. You are right about the expense, it was approx $600. This test was not suggested by my orthopedist surgeon, but I demanded it before surgery based upon my allergic history. In fact, he discouraged it stating allergies were rare. He did seem surprised at the number of metals I was allergic to. I was warned Medicare would not cover it. Still hopeful I wrote up a lengthy petition to Medicare to cover this test, justifying my need. I sent them complete records of all my other allergy testing in the past. Previously they covered patch testing for me twice. Patch testing cost $1,500 per kit. I also had the orthopedist write up a justification for allergy testing for me. I went through the lengthy appeal process and in the end was denied.
