Why I Use Function Health to Track My Autoimmune Healing

If you’ve followed my journey healing from severe eczema and psoriasis, you know that I'm trying to heal the root cause of my skin conditions instead of patching over the symptoms and kicking the can down the road.

Healing naturally takes time, and if you are off directionally, potentially way more time. Testing is crucial so that you know the healing protocol you are on has the highest chances of success. This is where Function Health has been an absolutely lifesaver for me.

The Problem With the Traditional Route

The traditional medical system is largely reactive.

You show up with symptoms.
You get a prescription.
You’re told to come back if it gets worse.

If you want deeper labs, you often have to:

  • Convince a doctor you “need” them
  • Wait weeks for an appointment
  • Hope insurance covers them
  • Risk surprise billing
  • Accept surface-level interpretation

When you’re dealing with severe eczema and psoriasis — systemic inflammatory conditions — that pace is too slow.

Healing requires iteration.

And iteration requires feedback.


What Function Health Actually Is

Function Health is a membership-based lab testing platform (currently around $365 per year) that gives you access to over 160 biomarkers annually.

These aren’t just basic cholesterol labs.

They include:

  • Advanced lipid markers
  • Inflammatory markers (like hs-CRP)
  • Insulin and metabolic markers
  • Thyroid hormones
  • Nutrients
  • Liver enzymes
  • Heavy metals
  • Hormonal markers
  • And much more

Labs are processed through Quest Diagnostics, but you order everything through Function’s dashboard.

You choose.
They schedule.
You get tested.
Results show up in a clean interface.

No gatekeeping.


Why This Has Been Powerful for My Healing

1. Speed of Iteration

If I test something — like:

  • Carnivore diet
  • Water fasting
  • L-glutamine supplementation
  • Red light therapy
  • Prednisone taper
  • Gut-focused protocol shifts

I can re-test biomarkers quickly.

I don’t have to wait 6 weeks to “ask permission.”

That speed matters.

Autoimmune healing is not static.
You make adjustments.
You observe.
You adjust again.

Function supports that loop.


2. Cost Transparency (Especially If You’re Self-Employed)

I’m self-employed and use health sharing instead of traditional insurance.

That means:

  • My monthly healthcare costs are lower.
  • I’m not relying on insurance to approve exploratory labs.
  • I can budget intentionally for testing.

When you try to order labs individually through Quest as a self-pay patient, costs can add up quickly.

Bundled under Function’s membership, the per-biomarker cost becomes very reasonable.

In my experience, many of the tests I wanted would have cost more if ordered individually.

And I wouldn’t have had the longitudinal dashboard.


3. Longitudinal Tracking (This Is the Real Value)

One lab result is interesting.

A trend over time is powerful.

Function stores all your biomarkers in one place. I can see:

  • Inflammation trends
  • Lipid changes during diet shifts
  • Liver enzyme changes
  • Thyroid shifts
  • Nutrient improvements

Eczema and psoriasis are not just skin conditions.

They are systemic inflammatory conditions.

Patterns over time are where insight lives.


4. AI That Understands My Labs

Function includes an AI chat that has access to your biomarker history.

I can ask:

  • Why would LDL increase during fasting?
  • What does ferritin mean in the context of inflammation?
  • Should I be concerned about this liver enzyme shift?

It doesn’t replace a doctor.

But it gives structured, contextual explanations immediately.

Compared to a rushed 10-minute appointment, this depth is incredibly helpful.


Who This Is For

Function Health is probably not for everyone.

If you:

  • Want your doctor to fully direct everything
  • Don’t care about biomarkers
  • Aren’t interested in root-cause exploration

Then it may not be necessary.

But if you:

  • Are investigating autoimmune conditions
  • Want to track inflammation deeply
  • Care about preventive care
  • Are self-employed or on a high-deductible plan
  • Want faster iteration without medical gatekeeping

It can be an incredibly powerful tool.

Important Disclaimer

This is not medical advice.

Function Health does not replace a physician. It’s a tool that helps you gather data so you can become a more informed participant in your healthcare.

For me, that shift — from passive patient to active investigator — has been essential.

Severe eczema and psoriasis forced me to take ownership.

Data gives you clarity.

Clarity gives you direction.

And direction is what root-cause healing requires.
