Are you talking about the levels in the blood? If so, it's called the IFX test from Prometheus labs and yes I have about 2 years ago. I wasn't sure if I had the proper amount because I was still having some issues. Found out that my levels were fine but the Colazal I was on at the time was the culprit.
