There is a moment I have experienced many times as a physician. A patient sits across from me, sometimes exhausted, sometimes frustrated, and sometimes fighting back tears, and says something like this: “They told me my labs are normal, but I know I don’t feel well.”
I believe them.
Laboratory testing is extraordinarily valuable. I order labs. I study labs. I appreciate the objective information they give us. Modern medicine would be unrecognizable without them. But somewhere along the way, we began behaving as though the laboratory value itself was the patient.
It is not.
A number on a page is one piece of information about a living, breathing, enormously complex human being. It tells me something. It may tell me something very important. But it does not tell me everything.
I often return to an old lesson in medicine attributed to Sir William Osler: listen to the patient, because the patient will tell you what is wrong. That philosophy has become even more meaningful to me over the years. A person's story is data too. Their physiology matters. Their genetics matter. Their environment matters. Their relationships, stress, sleep, beliefs, history, nutrition, sense of agency, and capacity to respond to adversity matter.
In Anatomy of a Soul's Calling, I write about medicine as a relationship and about listening not only to disease but to the whole human being. I describe the body as possessing an inherent capacity for healing when we help create the conditions in which healing can occur.
That is why I do not believe a laboratory reference range is the gold standard of patient care. The patient is.
A Laboratory Test Is a Snapshot, Not the Whole Movie
Think of a laboratory test as a photograph taken during a much longer movie.
It may be a very useful photograph. It can show us blood sugar, thyroid markers, nutrient levels, inflammatory signals, hormone values, liver function, kidney function, or hundreds of other physiologic measurements. But the human body is dynamic. We are continually responding to food, sleep, movement, relationships, medications, hormones, infections, stress, trauma, environmental exposures, age, and the world around us.
A snapshot cannot tell the entire story.
This is not a rejection of conventional laboratory testing. Far from it. It is a call to put laboratory information back into its proper context.
Even the larger field of precision medicine has moved toward this understanding. The National Institutes of Health describes precision medicine as an approach that considers differences in genes, environment, and lifestyle rather than assuming that every person will respond like an “average” patient. (National Institutes of Health)
That makes intuitive sense to me. Humans are not averages. And this is where my integrative approach begins to widen the lens.
Your Genome Is a Blueprint, Not a Verdict
One of the tools I find fascinating is genomics.
Our genes can help us understand inherited tendencies involving nutrient metabolism, hormone metabolism, inflammatory pathways, neurotransmitter function, detoxification pathways, cardiometabolic health, and other biological processes.
But I want to make something very clear: genes are not destiny.
Your genomic information is better thought of as a blueprint containing possibilities and predispositions. What happens with that blueprint can be influenced by many factors, including lifestyle and environment.
That is precisely why I do not want someone receiving a genomic report and walking away frightened because they have a particular variant. Information without context can create anxiety rather than agency.
The useful question is not simply, “What genes do I have?”
The more useful question is, “Knowing something about my inherited tendencies, how might I care for this body more intelligently?”
That shift matters enormously. We move from fear to curiosity. We move from helplessness to participation.
We move from “This is what is wrong with me” toward “This is something I understand about myself.” That is an entirely different relationship with health.
Hormones, Stress, and the Conversation Happening Inside the Body
Depending on the individual and the clinical question, another lens I may consider is hormone and stress-response testing, including tools such as DUTCH testing.
The purpose is not to collect impressive-looking reports. Lord knows we have enough paper in medicine.
The purpose is context.
Hormone production and metabolism, along with patterns of cortisol and stress-response signaling, can add another layer to understanding what is happening physiologically. In the framework I have been developing, I think of this information as one possible way of looking at the body's current neuroendocrine landscape rather than as an isolated answer unto itself.
And again, a test cannot replace a complete medical evaluation. It does not diagnose every endocrine problem, nor should it be treated as though it does.
The goal is integration.
What does the laboratory information mean in the context of the person's symptoms, medical history, sleep, stress load, medications, relationships, nutrition, stage of life, and lived experience?
Now we are practicing medicine.
The Gut Is Another Part of the Conversation
Then there is the gastrointestinal ecosystem.
There is increasing interest in the relationship among the gut, immune system, metabolism, and brain. In selected situations, stool testing such as GI-MAP may provide another lens through which to look at digestive function and microbial patterns.
But I want to resist the temptation to turn every health concern into a microbiome problem.
The gut matters enormously.
It is simply not the whole person either.
A GI test should not be expected to explain every symptom or replace appropriate evaluation of gastrointestinal disease.
What it can sometimes do is add another piece to the puzzle.
And that is really the theme here. We are gathering pieces, but we must continue looking at the picture they belong to.
The same is true for micronutrient and metabolic testing. Nutrient patterns may help us explore questions involving energy, cellular function, metabolism, and dietary sufficiency. But more data is not automatically better care. Testing is valuable when it changes what we understand or what we reasonably choose to do next.
Otherwise, we are simply creating prettier binders.
Perhaps very expensive binders.
The Part of Health That Cannot Be Put Into a Test Tube
Now we come to an area I believe medicine still does not adequately address.
You. Not your blood. Not your microbiome. Not your genome.
You.
What has happened in your life? What relationships surround you? How safe do you feel within yourself and your world? What happens when life does not go according to plan? What do you believe about your body? What are you afraid of? Where have you stopped trusting yourself? What patterns do you continue even though some part of you knows they are no longer serving you?
These are not frivolous questions.
The biopsychosocial model of medicine has long recognized that biological, psychological, and social factors interact in health and illness. Research has also emphasized that a patient's subjective experience is relevant to both humane care and clinical outcomes. (PubMed Central (PMC))
We cannot meaningfully talk about whole-person health while politely ignoring the person's actual life. This is where mindset enters the conversation. And when I use the word mindset, I do not mean pretending everything is wonderful.
I do not believe you can paste a positive affirmation over grief, trauma, anger, fear, exhaustion, or an unhealthy relationship and call it healing. That is not transformation. Sometimes healing asks us to face the music.
Neural Resilience: Staying Connected to Yourself
I use the term neural resilience to describe something more nuanced than simply “being strong.”
Neural resilience, in the framework I teach, is the capacity to experience emotional and physiological activation while maintaining, or recovering, access to present-moment awareness, connection, flexible thinking, context, and intentional action.
Notice what that definition does not say. It does not mean remaining calm every minute. It does not mean never feeling afraid. It does not mean becoming endlessly positive.
It means developing a greater ability to remain connected to yourself while life is happening. That changes how we engage with our health. Because knowing what to do and being able to do it are two completely different things.
A person may intellectually understand that sleep matters, but continually sacrifice sleep because their identity is tangled up in productivity.
They may know movement is beneficial but live in an all-or-nothing relationship with exercise.
They may understand that a relationship is chronically dysregulating them but remain afraid to establish a boundary.
They may know their body needs nourishment while continuing to treat food as punishment.
No laboratory test can resolve those conflicts for us. Eventually, there is an invitation to take responsibility. Not blame. Responsibility.
Those are very different words.
Your Health Requires Your Participation
This is where transformation becomes personal.
There are moments when we must acknowledge that we cannot outsource our health entirely to a physician, medication, supplement, laboratory, wearable device, or beautifully organized wellness plan.
We have to participate. Sometimes that means taking the supplement consistently. Sometimes it means going to bed. Sometimes it means changing how we eat. Sometimes it means asking for help. Sometimes it means saying no. Sometimes it means finally grieving. Sometimes it means recognizing that the belief “I will always be sick” has quietly become part of our identity.
And sometimes it means becoming willing to imagine ourselves well.
I use the word manifestation carefully here because I do not believe thoughts magically override biology. Illness is not evidence that someone failed to think positively enough. That kind of message is neither compassionate nor scientifically responsible.
But I absolutely believe our beliefs influence our behavior, attention, relationships, expectations, and willingness to engage with change.
If you fundamentally believe nothing can improve, you are likely to approach your health differently than someone who can hold the possibility that change is available.
Hope matters. Agency matters. Meaning matters. Self-compassion matters.
The ability to picture a healthier life matters because we are far more likely to build a life we can first imagine ourselves inhabiting.
The Gold Standard Is Integration
So, what is the gold standard? For me, it is integration. It is conventional laboratory testing when appropriate. It is genomic information when useful. It may include hormone and stress-response testing such as DUTCH testing. It may include assessment of the gastrointestinal ecosystem through GI-MAP when clinically relevant. It may include micronutrient and metabolic assessment.
It includes nutrition, movement, sleep, environment, relationships, stress physiology, and behavior. And it includes something medicine has too often treated as an afterthought: the human being who must actually live the plan. That means examining mindset, emotional patterns, beliefs, self-connection, meaning, agency, and neural resilience.
My work has increasingly brought me back to this central truth: a person is not a collection of laboratory abnormalities waiting to be corrected. A person is a living system.
Body, mind, relationships, history, environment, spirit, choices, biology, and story continually communicate with one another. We do not heal a spreadsheet. We care for a person.
A Different Kind of Health Journey
This philosophy is at the heart of our six-month program.
It is designed for people who are ready to move beyond collecting isolated pieces of health information and begin understanding how those pieces relate to one another.
Over six months, we look at the biological landscape while also exploring the lived landscape. Depending on individual needs and clinical relevance, that may involve genomics, hormone and stress-response patterns, gut health, micronutrient and metabolic information, alongside nutrition, sleep, movement, mindset, emotional patterns, beliefs, resilience, and the very practical work of making sustainable change.
The laboratory testing is not the transformation. The interpretation is not the transformation.
Even my guidance is not the transformation.
The transformation happens when information becomes awareness, awareness becomes choice, and choice is practiced long enough to begin becoming a different way of living.
That requires something from me as a physician. And it requires something from you.
I will bring curiosity, medical knowledge, pattern recognition, guidance, honesty, and deep respect for your story. You bring your willingness. Your willingness to look. Your willingness to ask questions. Your willingness to become curious about your biology without being ruled by it. Your willingness to face the places where change may be asking something of you. Your willingness to participate in your own life.
There are no guarantees in healing, and there should not be. Human beings are far too complex for promises neatly wrapped with bows. But there can be partnership. There can be knowledge. There can be agency. There can be a deeper relationship with the body you inhabit.
And there can be the possibility of transformation. If you are ready for a different kind of health journey, our six-month integrative program may be the place to begin.
Not because we have one magical test. Not because I possess one magical answer. But because we are willing to look at the whole map together.
Perhaps the most important laboratory of all is the life you are living. And that life deserves our attention.
With love and holding space for your transformation,
Dr. Louder
