Why “NORMAL” Lab Results Don’t Mean You’re HEALTHY
Why This Matters
Most lab tests are graded one way: normal or abnormal. That works fine for catching disease, but it misses everything in between. Chronic conditions like diabetes and thyroid disease don't show up overnight. They build slowly, often over 7 to 10 years, and for most of that time your labs will still say "normal." Meanwhile you're tired, foggy, and not performing the way you used to.
This is the gap functional medicine tries to close. Instead of only asking "is this a disease or not," it asks "is this number where a healthy, thriving person's number would be?" Catching a small drift early is a lot easier to correct than waiting until it becomes a full diagnosis. That's why understanding your own lab values, not just the lab's normal range, matters for anyone in Henderson or Las Vegas who feels off despite a clean bill of health.

2-minute summary
Dr. Krugly, a board-certified chiropractic sports physician with a diplomate in sports medicine, breaks down why "normal" lab results don't always mean your body is running well. Standard labs are built from a bell curve of the local population. If that population includes a lot of people who are pre-diabetic, overweight, or on multiple medications, "normal" gets pulled toward what's common, not what's actually healthy.
He walks through several markers where a tighter, more optimal range tends to predict how people actually feel:
- Thyroid (TSH): Standard range is roughly 0.5 to 4.5. Most patients feel and function better between 1.8 and 3.0, and around 2.5 for fertility.
- Ferritin (iron storage): He looks for a range of roughly 40 to 100, with timing of the draw mattering for female patients close to their cycle.
- Vitamin D: Ideally 40 to 80. Since it's fat soluble, a low result can also point to a gallbladder or fat absorption issue.
- Vitamin B12: He doesn't want to see patients drop below 600, since lower levels are linked to fatigue and neurological symptoms.
- Inflammation markers: C-reactive protein at 1 or below, with homocysteine checked as a backup marker since it can damage the lining of blood vessels over time.
He also stresses that a lab value never stands alone. A TSH that's technically "in range" but paired with thinning eyebrows, dry skin, and a slow Achilles reflex still points to a thyroid problem worth addressing. Reading labs well means connecting the numbers to the patient in front of you, not just checking a box.
Key Takeaways
- "Normal" on a lab report is based on the average person tested at that lab, not necessarily a healthy person.
- Chronic disease develops slowly, which means there's a long window where labs still look fine but the body is already drifting.
- Thyroid, iron, vitamin D, B12, blood sugar, and inflammation markers all have an "optimal" range that's often narrower than the standard lab range.
- Symptoms and physical exam findings should be read alongside the numbers, not instead of them.
- Autoimmune conditions rarely travel alone, so one diagnosis is a reason to screen for others.
Frequently Asked Questions
If my labs are "normal," why do I still feel terrible?
Because "normal" is a statistical range, not a guarantee of good health. Your result can sit inside that range and still be far from where your body performs best. This is exactly the gap functional medicine testing is built to find.
What's the difference between free and total thyroid hormone?
Total hormone measures everything in your bloodstream. Free hormone measures what's actually available for your cells to use. You can have a normal total number and still run low on free hormone, which is one reason a basic TSH test alone can miss thyroid problems.
Can an infection throw off my iron or ferritin results?
Yes. Ferritin rises during infection because it acts as part of the body's immune response, so a recent illness can artificially raise or lower both markers. That's why the full clinical picture, not just the number, matters when your results are reviewed.
How much does a full functional medicine lab panel cost?
Out of pocket through a typical lab, a comprehensive panel like the one described in the video can run around $1,300. Through Agape's negotiated lab pricing, patients typically pay closer to $150 for the same panel.
