How to get IL-6 testing?

Elevating a single inflammatory cytokine (IL-6) lifelong is sufficient to, in some ways, prematurely age mice

Crp is a good proxy, but I think il-10 is the issue.

I’ve gotten IL-6 measured via Quest Diagnostics

(a bit more expensive than other standard markers, so I don’t do it that often)

If you live in the US, Life Extension Foundation (LEF) offers it through Labcorp for $75.

Isn’t CRP proxy for IL-6 and good enough alternative?
Why do you test IL-6? What information do you get that CPR won’t provide, when we are talking general health?

John H can perhaps comment on differences.

One that I’ll continue to use it is that my hs-CRP is always under the lowest detectable level, while the IL-6 is not - so I hope to be able to see trends in IL-6 that I can’t see (the Quest or Labcorp in the US)

Edit: actually, just went back to the test I’m below the measurement threshold of the quest IL-6 test too, so it’s sensitivity is not helpful in the way I thought.

I would need to read up more to say anything useful. I have not tried to get il6 as crp seems a good proxy and i get it in the standard panel.
