In this post, I’ll cover everything you need to know about ferritin and hypothyroidism. The ferritin test is a simple blood test, and it is one of the most important tests you should have if you have Hashimoto’s disease, Graves’ disease, and hypothyroidism. Ferritin is a storage form of iron, and the ferritin level test can tell you if your iron stores are low and need to be increased. The ferritin test is rarely ordered by conventional doctors, so many patients are left with the signs and symptoms of hypothyroidism when it is actually their low ferritin levels that are causing their health problems. The first issue with iron is that iron deficiency may be quite severe, but blood markers such as hemoglobin and the red blood cell count may be normal. This leaves many patients, especially women, misdiagnosed as not having anemia.
The ferritin test may be the most important blood test you ever get, especially if you have a thyroid problem.
When I began my training in the diagnosis and management of internal disorders immediately after graduation, one of the first things we studied heavily was blood chemistry analysis. My teachers always stressed the importance of taking a careful look at iron levels in the blood and a rare test known as the ferritin test.
What is ferritin?
Ferritin is an iron-containing protein and is the primary form of iron stored inside your cells. Even though there is a small amount of ferritin released into your bloodstream, it is an accurate marker of how much iron is actually stored in your body. Iron is primarily stored in your liver, muscles, spleen and bone marrow but if you have too much it can accumulate in your organs and the brain.
