Testing / Core Metabolic Panel

For LL-37 · Antimicrobial · Mucosal Immunity

Your immune baseline. Before the cathelicidin stack.

LL-37 is the only human cathelicidin — a host-defense peptide that modulates innate immune response, gut mucosal integrity, and systemic inflammation. This panel documents the inflammatory and nutritional baseline your physician needs to justify the prescription and track the resolution.

Why it matters

Three reasons this panel changes the conversation.

01

LL-37 is the immune signal your standard labs never measured

Cathelicidin deficiency underlies recurrent infections, impaired gut mucosal defence, and chronic low-grade inflammation. hs-CRP alongside albumin identifies this pattern objectively — and gives your physician both the prescribing trigger and the outcome marker in one draw.

02

Nutritional status is the other half of the immune picture

Albumin below 3.8 g/dL combined with elevated hs-CRP signals mucosal barrier dysfunction — exactly the phenotype LL-37 addresses. Without the albumin value, the prescription is based on symptoms alone. With it, the indication is documentable.

03

The 90-day retest tells you whether the protocol is working

hs-CRP and albumin both shift measurably over a 12-week LL-37 protocol. The baseline from this panel is the evidence the retest is compared against — without it, improvement is anecdotal.

Common questions

Everything you should know before ordering.

When will LL-37 be available to prescribe?

LL-37 is in the FDA review pipeline with formal review expected February 2027. Testing now establishes your immune and inflammatory baseline — your physician can write the prescription immediately when prescribing opens.

What is LL-37 and why isn't it widely known?

LL-37 is your body's own cathelicidin — produced in the gut lining, lung epithelium, and skin. It's the bridge between innate and adaptive immunity. Most standard labs don't test for it, which is why deficiency goes unrecognised despite causing chronic infection susceptibility and impaired healing.

Is this panel HSA/FSA eligible?

Yes. Physician-ordered diagnostic testing is HSA and FSA eligible. At a 32% tax bracket, the effective cost is approximately $115.
