Alternative test to C-Reactive Protein

Although I know for sure that scientifically CRP is proven to be confirmatory test for inflammation, it has never worked in my case. Even when I was in flare, my CRP would come out normal. I checked my records since I was diagnosed and it has been consistently recorded as less than 0.5 and I know I was in flare few times in that period.

Hence, I am looking for another test that I can use to test the level of inflammation. Has anyone done any other test than CRP to test the inflammation?

Thanks in advance.

Calprotectin stool test. Some use lactoferrin (also stool)

For Calprotectin, do they need any specific stool sample, like morning etc. or any sample is fine?

I'd say SED is not reliable according my person experiences. I had CRP of over 7 while my SED was at 1, totally normal, in my blood work.

Calprotectin is the way to go.
