Do I need a consultation first?

No. The free call is the only prerequisite. If you already have testing you want read instead, that is the Precision Health Assessment, one visit and a plan you keep, and its fee credits toward this if you go further.

Why does it take two months?

Metabolomics and stool culture run on their own timelines and cannot be rushed without losing accuracy. I also do not interpret anything until all three panels are back, because reading them together is the entire method.

Where does the blood draw happen?

At a Quest near you, ordered in advance so you walk in and out. The urine and stool collections happen at your intake visit, and I handle the shipping.

What if you find something serious?

I tell you directly and I help you get to the right specialist. This is an optimization evaluation, not a substitute for the care you already have. Some findings belong with a cardiologist or a gastroenterologist, and I will say so.

Is this functional medicine?

No. This is Health Optimization Medicine, a defined clinical framework with optimal ranges derived from healthy twenty-somethings. Every recommendation traces to a finding. Nothing goes in your plan because it is popular.

Am I going to end up on twenty supplements?

No. Most plans start with three or four things, and several of them are not products at all. I take nothing from any supplement company, so there is no reason for that list to be long.

How is this different from the consumer testing panels?

Those sell you the data. This is a physician reading the data in context, with a history and an exam behind it, and then sitting with you until you understand it.

What happens after the thirty days?

Nothing, unless you want it to. Most people take the plan and run it. If you want ongoing care we talk about it then, and never before.

Can I do this without home visits?

Yes. The kits ship to you, your blood is drawn at a lab near you, and both visits happen on video. Same panels, same synthesis, same plan, and it costs less than having me at your house. What it goes without is me seeing the place your health actually happens.

What does membership change about testing?

Inside the Precision Partnership, testing passes through at my cost with interpretation always included, as part of ongoing care rather than as a separate purchase. A Longevity Baseline can be how you start, or it can stand on its own.

Is this covered by insurance?

No, I do not bill insurance. You can use an HSA or FSA in most cases, and I provide documentation you can submit if you want to try.

The Longevity Baseline

Your health, measured properly.All 200 markers of it.

A standard annual measures about 40 markers, and nearly every one is looking for disease that has already arrived. This measures more than 200, read against optimal ranges instead of disease cutoffs. It is the foundation the rest of your care gets built on.

What a standard annual sees

Forty markers. Then two hundred.

Standard annual physical

About 40 markers

The Longevity Baseline

More than 200 markers

The forty are not wrong. They are answering a different question.

What gets measured

Three panels. Three different questions.

Each panel sees something the other two cannot. Read separately they are three folders of results. Read together they are one picture.

Advanced blood

Hormones, thyroid, nutrient status, inflammation, and the cardiometabolic markers a standard draw leaves out.

ApoB · Lp(a) · hs-CRP · fasting insulin · full thyroid · sex hormones with binding globulin · homocysteine · ferritin and iron studies

Organic acids

A metabolomic read from urine. How your mitochondria are running, where your B vitamins actually sit, what your detoxification pathways are carrying, and where the bottlenecks are.

Mitochondrial energy intermediates · neurotransmitter metabolites · functional vitamin markers · oxidative stress · bacterial and yeast metabolites

The gut

A full stool analysis with food sensitivity testing. Digestion, absorption, inflammation, and the microbiome, which quietly decides how much of everything else lands.

Pancreatic elastase · calprotectin · secretory IgA · short-chain fatty acids · bacterial and fungal culture · food sensitivity panel

All of it read through Health Optimization Medicine and synthesized into one picture. That is what makes it a foundation rather than a folder of results.

How it runs

Three stages, about two months

Metabolomics and stool analysis take the time they take. Reading them together is the point, so nothing gets interpreted until all of it is back.

The intake

A visit at your kitchen table. Full history, exam, and a look at what you live in and how you move. I collect the specimens there and order your blood in advance at a Quest near you, so none of the logistics land on you.

The measurement

Three panels and more than 200 markers, six to eight weeks while the labs run. You have my number the whole time, not only at the end.

The synthesis

This is the work. Every result read together against optimal ranges rather than disease cutoffs, then walked through with you at your table, marker by marker, until it makes sense.

The deliverable

You keep the Precision Health Plan

Not a portal login, and not a stack of PDFs from three labs. One written document in plain language: what your chemistry shows, what matters most and why, and the protocol to start. Every recommendation traces back to a specific finding. If I cannot point to the marker that prompted it, it does not go in the plan.

Thirty days of direct access afterward, so the first month of doing the work is not done alone.

The price

Two formats, by where the visits happen.

Recommended

In your home

Charlotte metro

Two home visits. I collect the specimens myself, and the visit includes the context that needs me in the room: what you live in, and how you move.

Virtual

Anywhere in North Carolina

Two virtual visits. The kits ship to you and your blood is drawn at a lab near you. Same panels, same synthesis, same plan.

The testing is the same either way. The panels are billed at my actual cost, with the invoice visible, and I make nothing on them. What changes between the two is whether I come to you.

I perform every visit myself. If I’m full when you call, I’ll tell you when I can start.

Talk to Dr. Tagge

We decide together whether this is the right measurement for you.

My commitment to you.

The Health Fiduciary Standard

When I recommend something, it’s because you need it, not because I make money on it.

The Fire Your Doctor Guarantee

Sixty days to decide it wasn’t worth it, and the fee comes back.

The Same-Day Guarantee

Reach me during business hours and I respond that same day. If I don’t, your thirty days of access extends by thirty more.

Worth it if.

This is for you if

You want to know what your biology is doing, not whether you have crossed a line yet.
You have symptoms nobody has explained and standard panels keep coming back fine.
You are already doing the work and want to know what to aim it at.
You want the measurement once, properly, before deciding anything else.

This is not for you if

You want a number today. This takes weeks, because the testing does.
You need care for something urgent. That is a different visit, and I will tell you to be seen.
You want a subscription and a monthly supplement box. That is not what this is.
You want the panels without the interpretation. I do not sell testing on its own.

“I came to Daniel after trying everything. He found bottlenecks in my metabolism that nobody had even looked for. The work he does is a different category of medicine.”

How this relates to the practice.

Members of the Precision Partnership get their testing at cost with interpretation included as part of ongoing care. A Longevity Baseline can be the way into the practice or a one-time measurement, whichever serves you.

I make house calls

Your life happens at home.

Now, your medicine can too.

Your doctor has never seen the place where your health actually happens. You spend most of your hours inside these walls. The air you breathe, the light in your bedroom, the water you drink, the food in your fridge and pantry. All of it shapes how you feel more than anything I could measure in an office.

So I come to you. You are at ease in your own home, there is no waiting room and nowhere to drive, and I see in an hour what a chart could never tell me. The plan I write is designed for the life you actually live.

The molecules you take, and the water you drink.
The food you buy, and the food you actually eat.
The light, air, and temperature in your sanctuary.
The air and light where you spend your evenings.

Your environment is data.
