What Your Lab Results Aren't Telling You
You've had bloodwork done and everything came back fine - but you still feel exhausted, foggy, or off. This is something I hear often in practice, and it's worth exploring.
Naturopathic lab interpretation uses a functional lens: we look at a broader range of markers and apply optimal reference ranges alongside standard ones. This can help identify patterns and opportunities for support that might not be visible otherwise.
Optimal vs. reference ranges
Take ferritin (stored iron) as an example. Reference ranges note anything above 30 µg/L as within range, but research suggests many people feel their best when ferritin is above 75 µg/L. If yours is sitting just above 30, there may be real room to support your levels - and that can make a meaningful difference in energy and wellbeing.
The same nuance applies to thyroid markers, vitamin D, B12, and others. A functional approach looks at where you sit within a range, not just whether you're inside it.
Markers worth exploring
- Full thyroid panel: TSH is a great starting point; adding free T3, free T4, and thyroid antibodies gives a more complete picture of thyroid function.
- Nutrient levels: Vitamin D, B12, magnesium, zinc, and iron together can reveal deficiencies that contribute to fatigue, mood changes, and more.
- Inflammatory markers: hs-CRP and homocysteine can provide early insight into cardiovascular and inflammatory health.
- Fasting insulin: A useful early marker for blood sugar regulation, alongside fasting glucose.
How I approach lab work
When I review labs - whether they're new or ones you've had for years - I look at the full pattern, not just individual markers. I also consider your symptoms, history, and goals alongside the numbers. A result that looks fine in isolation might tell a different story in context.
I can also order additional testing through naturopathic requisitions, including specialty panels that complement your existing care.
