Interleukin-6 Blood Test

Measures IL-6, a signalling protein involved in immune responses.

Measures

IL-6, a signalling protein involved in immune responses.

Why it matters

IL-6 is one of the cytokines that coordinate inflammatory responses — it's part of what triggers the liver to produce CRP.

It's measured much less often than CRP because it's less stable, more expensive and moves quickly. It's a research-adjacent marker in most consumer contexts rather than a routine one.

Before you collect

Recent illness, injury or intense exercise raises IL-6. Collect when otherwise well.

Suits

People whose practitioner has a specific reason to measure IL-6 rather than CRP.

Your next step

Once you have your results, book with a Canwell naturopath, nutritionist or practitioner to talk them through and build a wellness plan that suits you. Book with Canwell
