I knew I had metal allergies because the only metal jewelry I can tolerate is gold or stainless steel. I used the same lab and am so grateful I paid the $600 out of pocket. Medicare will not cover this test.
My results were disappointing although I was not surprised based on jewelry issues for years. I tested positive to nickel, chromium, aluminum and 2 others. I didn't test positive to titanium.
However, my ortho told me even the purest titanium has traces of other metals in it. The ceramic coated implants are coatings over metals, normally titanium , they wear over time and then you are exposed to the titanium with traces of my allergic metals.
I cancelled my surgery.
