A Different Set of Questions
People who come to us for functional medicine have often already had bloodwork done. Sometimes a lot of it. They have been told their results are normal, but they do not feel normal, and they want to understand why those two things do not line up.
The gap usually comes down to what was tested and what was not.
Lab ranges and their limits
Standard lab reference ranges are built by measuring a value across large populations and defining normal as the range that covers most of the group. That range is designed to identify disease. A result inside it means you probably do not have the condition the test is screening for. It does not mean your body is functioning well, or that nothing is heading in the wrong direction.
This is not a criticism of standard medicine. Those tests do what they are designed to do, and they do it well. But there is a meaningful gap between "no detectable disease" and "functioning well," and standard panels do not measure much inside that gap.
We use testing that asks different questions: not just whether a threshold has been crossed, but how the body is actually working, and whether something is heading in a direction worth addressing now rather than later.
The timing problem
Most chronic health conditions build slowly. Insulin resistance develops over years before fasting glucose moves out of range. Hashimoto's produces measurable antibody activity long before TSH is affected. Adrenal stress patterns become entrenched before cortisol levels show anything unusual on a morning blood draw. Hormonal changes in perimenopause are well underway before standard hormone panels flag anything.
By the time standard testing catches a problem, the window for the most effective early work has often already closed, or at least narrowed. Once a condition has progressed far enough to be treated with medication, medication is usually the right call. But before that point, the primary appropriate tools are nutrition, exercise, sleep, stress management, and nutritional support. Those tools work best when the problem is caught early. We use testing that catches it early.
The specific tests
Fasting insulin alongside fasting glucose. Standard blood sugar testing measures fasting glucose and A1C. These are late markers. Fasting insulin is the earlier signal. Insulin resistance develops when the body stops responding efficiently to insulin, and the pancreas compensates by producing more of it. Glucose stays normal for years during this process because the extra insulin is keeping it in check. But elevated insulin is already driving fat storage, inflammation, and hormonal disruption. A fasting insulin catches this pattern years before fasting glucose moves, while the window for lifestyle work is still wide open and medication is not yet indicated.
Full thyroid panel instead of TSH alone. TSH measures what the pituitary gland is telling the thyroid to do. It does not measure what the thyroid is actually producing, how well the body is converting thyroid hormone into its active form, or whether the immune system is attacking thyroid tissue. A person can have a normal TSH and still have low free T3, elevated reverse T3, or significant TPO and thyroglobulin antibodies indicating Hashimoto's disease. We run the full panel because those are different questions with different answers, and the answers change what we do.
Cortisol rhythm testing instead of a single cortisol level. Cortisol follows a daily rhythm: high in the morning, dropping through the day, low at night. That rhythm is what matters clinically. A single morning blood draw tells you the level at one moment. Salivary or urinary cortisol measured at multiple points across the day tells you whether the rhythm is intact. A person can have a normal morning cortisol and still have a disrupted pattern that explains fatigue, poor stress tolerance, afternoon crashes, and sleep that never feels restorative.
Comprehensive hormone testing including how hormones are cleared. Standard hormone panels measure levels in circulation at a single point in time. They do not tell you how hormones are moving through a cycle, how they are being processed by the liver, or how the body is clearing them. Two people with identical serum estrogen can have very different patterns in how that estrogen is processed, with very different effects on symptoms, mood, and long-term health. We use testing that captures the fuller picture because total levels alone often do not explain what someone is experiencing.
Inflammatory and cardiovascular markers beyond a standard lipid panel. A standard cholesterol panel tells you total cholesterol, LDL, HDL, and triglycerides. It does not tell you whether inflammation is contributing to cardiovascular risk, whether homocysteine is elevated, or whether LDL particles are the type more associated with arterial damage. High-sensitivity CRP and homocysteine catch inflammatory cardiovascular risk at a stage where nutrition and lifestyle work are the primary appropriate tools and medication is not yet indicated.
Nutrient levels that affect how you function day to day. Standard panels rarely check vitamin D, magnesium, B12, iron status beyond hemoglobin, or the other nutrients closely linked to energy, mood, cognitive clarity, immune function, and hormonal balance. Deficiencies in these areas are common, are often the missing piece behind symptoms that do not fit a standard diagnosis, and are straightforward to address once identified.
Turning results into a plan
We use the results to build a specific approach for your situation. The goal is to address what we find at the stage we find it, using the tools that fit that stage. For conditions that have not yet progressed to the point where medication is indicated, those tools are nutrition, exercise, sleep, stress management, and nutritional support. That is not an alternative to conventional medicine. It is what fits the stage of the problem.
For people who are already on medication for a condition, we work on the factors the medication is not covering. Any changes to your prescriptions stay between you and your prescribing doctor.
If you have been told your labs are normal but you do not feel normal, or if you want to understand what is going on before something progresses further, a functional medicine consultation is a reasonable next step.
