Your Labs Were Normal,
So Why Do you Feel Terrible?
by Giacomo Kyle Hatanaka, LAc, MAcOM | Hidden Summit Acupuncture
A woman came into the clinic recently, late thirties, sharp, clearly someone who takes her health seriously. She’d been dealing with insomnia, heart palpitations, headaches, and an energy level that had gradually flatlined over the past year or two. She’d done the responsible thing: she went to her doctor, she got a full panel run, waited for answers.
I think you can predict what the results were. Normal. All of them. Normal, because you or someone you know have been there, right? And you know what comes next, too: her doctor, apparently satisfied, sent her on her way.
She showed up at my office about a week later. Talked about how she had “exhausted all her options.” Like not only she was exhausted, but the options that have been putting up with her were exhausted, too. But you won’t believe how many times I’ve heard that exact phrase. By the time most people walk through the door of an acupuncturist, they are desperate. They don’t know what to do. And I get it. I just try not to take offense when they imply “all their options” does not include me.
I’m not saying all this to be glib about conventional medicine. There are things it does extraordinarily well (where would we be without an ER?). But there is a specific and very common way that standard lab work fails us, and I think it deserves a direct conversation, because it’s leaving a lot of people stranded between feeling genuinely unwell and being told, “Nothing is wrong. Go away.”
What "Normal"
Actually Means
Here’s the thing that most people don’t realize about standard lab reference ranges: they were not derived by studying healthy, optimally functioning people and finding out what their numbers looked like. They were derived by taking a large population sample — which includes plenty of sick, sedentary, chronically stressed, nutritionally deficient people — running their numbers, and defining “normal” as roughly the middle 95 percent of whatever came back.
That’s wild, right?
What this means in practice is that “normal” is a statistical description, not a health endorsement. It means you are not an outlier in a general population that includes a lot of people who aren’t particularly well. It does not mean you are thriving. It does not mean your levels are optimal. It just means you aren’t among the 2.5% of society’s most unhealthy people.
That cracks me up in a dark/Giacomo kind of way.
Your doctor telling you your labs are normal is, in many cases, telling you that you are sufficiently average. Which, if you came in because you feel terrible, is not especially useful information.
The functional medicine world has been pointing this out for years, and while functional medicine has its own problems with overclaiming, the core critique here is valid and well-supported: reference ranges optimized for detecting disease are not the same thing as ranges optimized for detecting whether someone is actually well. Those are different questions, and conventional lab interpretation is set up to answer only the first one.
The Thyroid
Problem
I want to pivot here for a minute, because this is the one that frustrates me most consistently. I see it constantly, and the stakes are real.
Standard thyroid assessment usually measures TSH (thyroid stimulating hormone) and sometimes T4. The conventional reference range for TSH runs roughly from 0.5 to 4.5 or 5.0 mIU/L depending on the lab. If you land anywhere in that window, you’ll typically be told your thyroid is fine.
But here’s what that range doesn’t tell you: TSH is actually a pituitary hormone, not a thyroid hormone. It’s the signal your brain sends to tell your thyroid to produce more hormone. So a high TSH actually means your thyroid is struggling to keep up with demand, and your brain is yelling at it louder to compensate. Many functional practitioners consider anything above 2.0 to 2.5 worth watching closely, especially in the presence of symptoms. The conventional ceiling of 4.5 or 5.0 means you can be quite symptomatic and still be waved through.
And most standard panels don’t even measure the full picture. They don’t look at free T3, which is the active form of thyroid hormone your cells actually use. They often don’t run thyroid antibodies, which would tell you whether an autoimmune process like Hashimoto’s is underway, a condition that can cause significant symptoms for years before TSH moves enough to trigger treatment. You can have a full-blown autoimmune attack on your thyroid, with the fatigue, the cold intolerance, the brain fog, the difficulty losing weight no matter what you do, and walk out of your appointment with a clean bill of health because the one number they measured landed inside a range that was defined too broadly to catch it.
I have lost count of how many patients I’ve seen in exactly this situation. Women in their thirties and forties with a textbook Hashimoto’s symptom picture who’ve been told, repeatedly, that their thyroid is fine. Some of them have been told this for years.
The Prediabetes
Shrug
I have a patient I see weekly, a guy under enormous work stress, eating poorly because he genuinely doesn’t have the bandwidth to do otherwise, carrying extra weight, dealing with circulation issues in his legs. His doctor recently reviewed his labs and told him he was “barely prediabetic,” which in Doctorworld means “basically fine.” A technicality. Close to a line but not over it.
My patient relayed this to me with something approaching relief. Then he asked if I could do something about his blood pressure.
I want to be careful here, because he’s not wrong that acupuncture can support blood pressure regulation. But the picture of himself he’s bringing into my clinic is not a “barely” picture. It is a picture of a metabolic system under serious strain, heading somewhere specific if nothing changes. Prediabetic with those accompanying signs is not “almost fine.” It is a window (probably still a wide one, but a window) to intervene before the trajectory finishes its sentence.
The A1C reference range considers anything below 5.7 normal, 5.7 to 6.4 prediabetic, and 6.5 and above diabetic. But research increasingly supports that metabolic dysfunction (insulin resistance, impaired glucose clearance, the downstream inflammation that damages vessels and nerves) begins well before those thresholds. A fasting glucose that’s been creeping up for three years and an A1C of 5.6 can represent significant pathology in progress. What it doesn’t represent is a reason to relax.
The “pre” in prediabetic has a way of making people feel like they’re safely in a waiting room rather than already in the building.
The Whole Vitamin D
Situation
The conventional sufficiency threshold for Vitamin D (typically defined as 20 ng/mL serum 25-hydroxyvitamin D) is almost certainly too low, and the evidence for this has been accumulating for a while.
Most functional practitioners and a growing number of researchers consider optimal levels to be somewhere between 40 and 60 ng/mL, with some literature suggesting higher for certain conditions. The official threshold was set primarily to prevent deficiency diseases like rickets, not to optimize immune function, mood regulation, cardiovascular health, or cancer risk reduction. All areas where Vitamin D appears to play meaningful roles at levels above the official floor.
But there’s another layer to this that almost never gets discussed in a standard appointment: Vitamin D metabolism is genetically variable. Specific polymorphisms in the VDR gene (the gene encoding the Vitamin D receptor) affect how efficiently your body converts sun exposure and dietary intake into usable Vitamin D, and how effectively your cells respond to it. Two people with identical serum levels can have dramatically different functional availability of the vitamin at the cellular level, depending on their receptor genetics. Testing everyone against the same threshold and treating the number as the whole story ignores this entirely.
If you live in a place like Boise, where winters are real and sun exposure drops significantly for months at a time, and you have any of the common VDR variants, a serum level that looks “sufficient” may not be functionally sufficient for you specifically. This is not fringe science. It’s just science that hasn’t made it into the standard fifteen-minute appointment yet.
What the Appointment Structure
Doesn't Have Room For
I want to say something about this carefully, because I’m not interested in cheap shots at physicians who are, in most cases, doing a genuinely difficult job under genuinely bad structural conditions.
The average primary care appointment in the United States runs about fifteen minutes. In that fifteen minutes, a physician is expected to review your history, address your concerns, order appropriate tests, interpret results, manage existing conditions, and document everything in a way that satisfies insurance requirements. The system is not designed to find the early, subtle, pattern-level dysregulation that sits between “you have a diagnosable disease” and “you are optimally well.” It’s designed to identify pathology at a threshold that justifies a billable intervention.
This is not a conspiracy. It’s an incentive structure, and it produces predictable outcomes. One of those outcomes is that a lot of people who feel genuinely unwell get told their labs are normal and leave without answers, because the tool being used was built to answer a different question than the one they were asking.
The question they were asking is: why do I feel like this. The question the lab panel was built to answer is: do you have a disease we’re currently equipped to treat.
Those are not the same question.
Where Does Acupuncture
Fit Into All this?
I’m not going to claim that acupuncture replaces lab work or that we can diagnose thyroid conditions or metabolic disease. We can’t, and we don’t try.
What I can say is that the framework we work from (rooted in pattern recognition, in how systems are relating to each other, in the gap between how someone looks on paper and how they actually feel) is well suited to exactly the kind of picture that falls through the cracks of standard lab interpretation. We’re not looking for a threshold. We’re looking at how you’re functioning across multiple systems simultaneously and trying to understand what the pattern is trying to tell us.
The woman who came in last week with normal labs and a list of symptoms (the insomnia, the palpitations, the headaches, the low energy), we didn’t need an abnormal TSH to start working with her. We could see the pattern. And we could start addressing it.
That’s usually where we come in. Not as a last resort, though I understand why we end up there. As a different set of eyes, asking a different set of questions, working with what’s actually happening rather than what the reference range did or didn’t flag.
