In functional medicine, we focus on uncovering the root causes of illness—not just managing symptoms. Unfortunately, many practitioners (and even some patients) are drawn to running very small lab panels because they’re less expensive up front and quicker to review. While this may sound convenient, the reality is that small panels are often inconclusive and don’t provide the depth needed to guide meaningful care.
The Problem With Small Panels
Running only a handful of labs can create a false sense of security. For example:
- A basic thyroid panel that only includes TSH may look “normal” while deeper thyroid dysfunction goes completely unnoticed.
- A single inflammatory marker like CRP may miss underlying issues if homocysteine, fibrinogen, or other markers aren’t checked alongside it.
- Lipid testing limited to just total cholesterol and LDL tells us very little about cardiovascular risk without a full ratio breakdown.
- Some practitioners may piece meal functional tests for a single or a few systems rather than a comprehensive functional panel to give the total picture of what your body is doing – not allowing for a true all systems functional assessment.
In other words, smaller panels often leave both the patient and practitioner guessing. Functional medicine is about patterns, and you can’t see patterns without enough data.
Why Patients Sometimes Request Smaller Panels
It’s natural for patients to want flexibility or to keep costs down. Some may only want a few markers they’ve heard about online. While this is understandable, it is not in the patient’s best interest if it means overlooking critical pieces of their health puzzle.
The Hidden Truth: Small Panels Are More Profitable for Practitioners
Here’s something most patients don’t realize: running smaller panels is actually more profitable for the practitioner than ordering comprehensive labs.
Why? Because:
- Small panels are billed individually. Each small set of labs carries its own cost, and when patients need multiple sets over time, it adds up quickly.
- Comprehensive panels offer bundle discounts. Larger, more inclusive panels are negotiated at a lower cost per test. While this saves the patient money, it reduces the practitioner’s markup and profit margin.
- Less data = more repeat testing. When the big picture is missed, patients often come back for additional tests—leading to more revenue for the office, but more expense and frustration for the patient.
At our practice, we choose the opposite approach: comprehensive, bundled panels that give us real answers at the lowest possible cost to the patient. It may not be as profitable for us, but it’s the right thing to do for your health.
The Bottom Line
In functional medicine, data drives insight. Running very small panels may seem appealing, but they rarely provide enough clarity to guide effective care. And while they may be more profitable for the practitioner, they are not in the best interest of the patient.
By using comprehensive functional labs, we ensure our patients receive answers that are accurate, actionable, and deeply personalized—while also keeping long-term costs as low as possible.
Your health deserves more than guesswork—it deserves a complete picture.
Our Functional Medicine Testing Philosophy
At our office, we take a comprehensive approach to lab testing. This doesn’t mean ordering every possible lab, but it does mean looking at the full scope of systems most likely to contribute to dysfunction. By doing so, we gather a complete picture that allows us to create personalized, targeted treatment strategies.
Here are the core labs we include in our functional medicine panels (from 2 separate laboratories) that costs roughly $600 with our lab co-op (retailing for around $5,000):
Each lab value is linked to a glossary description for your reference.

Specialized Testing for Fertility
For both men and women, we include additional fertility-focused labs when there are concerns about reproductive health. These help us identify subtle imbalances that may be overlooked with standard panels and guide targeted strategies for optimizing fertility naturally.
