Your Iron Labs Are Being Read Wrong
The difference between iron deficiency and anemia of inflammation, and why one number gives it away
My client (who we’ll call Rose) had been taking iron for 19 months.
She had spent hundreds of dollars on iron bisglycinate, desiccated spleen, taken the co-factors for absorption (like vitamin C), dosed exactly what the doctor told her. Her ferritin (storage form of iron) had climed from 22 to 68. On paper, the problem was being solved. Her doctor told her the numbers looked great and suggested she consider therapy for her fatigue.
Yet, she still struggled to climb a flight of stairs wihtout her heart punding like a drum out of her chest. Her hair was still running thin and falling out in the shower, her hands were still cold (even though it was mid summer), and when she finally brought me the full iron panel instead of the one number her doctor circled, the story fell apart before our eyes. Her serum iron was 41, her transferrin saturation was 11%, her TIBC (Total Iron Binding Capacity), the marker almost nobody looks at correctly, was sitting at 248 when it should have been climbing.
That panel was not describing a woman who needed MORE iron. It was describing a woman whose body had made a decision to HIDE the iron she already had, and had been making that decision every single day for that year and a half.
In a previous article I explored how bacteria may cause a reaction in the body to hide iron and how certain supplements like lactoferrin may play a role in correcting this process. However; I didn’t explore how to assess whether or not you maybe truly anemic vs experiencing anemia of inflammation.
In this article I hope to correct that so you can analyze your labs in a way that gives you more calrity on the subject.
TLDR: Here’s what I’ll be covering (and why its important)
Low iron on a blood panel can come from two completely different physiological situations, and they require different action steps to correct.
Iron deficiency means your warehouse is empty. Your body is in need of iron and either enough isn’t coming in or usage outweighs what is being put back into stock.
Anemia of inflammation means the warehouse is full and locked; however, body has iron and is deliberately refusing to release it, because inflammation triggers an ancient defense system that starves invaders of iron. This can be for emany reasons, which i’ll be exploring with you
The hormone that makes this decision is hepcidin. It is produced by your liver, driven up by the inflammatory signal IL-6, and it destroys the only door iron has to exit your cells.
TIBC and transferrin are the cleanest tell. They rise in true deficiency and stay flat or fall in inflammation.
Ferritin lies during inflammation. It is an acute phase protein and rises with immune activation, which means a “normal” ferritin does not rule out deficiency in an inflamed body.
Soluble transferrin receptor (sTfR) and reticulocyte hemoglobin (Ret-He) cut through the inflammation and report what the bone marrow is actually receiving.
The two conditions coexist constantly. Reading them as either/or is the mistake that costs people years.
Pushing iron into a hepcidin-blocked system wastes the iron, feeds pathogens, and irritates the gut. We’ll discuss how lowering inflammatory drivers can free up the warehouse.
