Ferritin is a blood cell protein that contains iron. It's important to understand that while ferritin itself does not circulate iron, it is a key marker used by healthcare professionals to assess your iron stores. The amount of ferritin in the blood reflects the total amount of iron stored in the body. Usually, ferritin levels are measured in nanograms per milliliter (ng/ml).
Measuring ferritin is common in routine blood tests, especially if there are symptoms of iron-related disorders. When your doctor assesses your ferritin level, they can get crucial insights into whether your body’s iron metabolism is functioning correctly.
Ferritin plays a vital role in the storage and release of iron, a mineral crucial for various bodily functions. Iron is essential for the formation of hemoglobin in red blood cells, which carries oxygen from the lungs to the rest of the body. Without adequate iron, your body cannot produce enough healthy oxygen-carrying red blood cells, resulting in iron deficiency anemia.
Moreover, ferritin also acts as an iron buffer, helping maintain iron in a non-toxic form even when body levels exceed nutritional needs. By doing so, it minimizes oxidative damage and keeps other cells and tissues safe from free radicals that excess iron can produce.
Having abnormal ferritin levels can indicate a range of health issues. Low levels of ferritin often suggest iron deficiency, which is the most common cause of anemia. Symptoms associated with low ferritin include fatigue, weakness, and shortness of breath.
On the other hand, high ferritin levels might suggest conditions such as hemochromatosis (wherein there is too much iron in the body), chronic inflammation or liver disease. High ferritin might also be seen in people who regularly consume too much iron or take high doses of dietary iron supplements.
Both extremes of ferritin levels require medical attention to determine the underlying cause and appropriate treatment.
The normal range for ferritin levels varies slightly depending on the lab, but generally, adult males should have levels between 20 and 500 ng/ml, and females should have levels between 20 and 200 ng/ml. These ranges can be lower or higher based on individual health conditions and labs.
If your ferritin levels are low, consider incorporating iron-rich foods such as red meat, beans, lentils, and fortified grains into your diet. Vitamin C-rich foods can also enhance iron absorption. If recommended by your healthcare provider, iron supplements can also help.
For high ferritin levels, it’s important to consult your doctor for potential causes and treatment options. This might involve dietary adjustments, medication, or other medical interventions.
