Ferritin

Optimal Result: 30 - 400 µg/dL, 5.37 - 71.60 µmol/L, 30.00 - 400.00 ng/mL, or 30.00 - 400.00 ug/L.

Understanding Ferritin and Iron in Your Body

Iron is a crucial element for our health, playing a vital role in oxygen transport throughout our body. Ferritin, a key protein in this process, acts as the body's iron storage system. Let's explore its importance and how it's measured.

The Role of Iron and Ferritin

Our bodies rely on iron in red blood cells to carry oxygen everywhere. Without enough iron, our red blood cells are unable to efficiently supply oxygen, potentially leading to a condition called anemia. Anemia can cause fatigue, weakness, and other health issues.Ferritin is a blood cell protein that holds iron and releases it in controlled intervals. It is produced by every cell in the body but is found most commonly in the liver, spleen, skeletal muscles, and bone marrow.

Ferritin Blood Tests

A ferritin blood test checks the amount of ferritin in the blood, which indicates how much iron is stored in your body. A healthcare professional might order a ferritin blood test to:

- Find the cause of anemia, especially iron deficiency anemia

- Detect inflammation in the body

- Diagnose iron overload conditions like hemochromatosis

- Monitor the effectiveness of iron treatments (whether to raise or lower iron levels)

Normal Ferritin Ranges

Ferritin levels are measured in nanograms per milliliter (ng/mL). Normal ranges vary by age and gender:

Age/Gender Normal Range (ng/mL)
0-1 month 25-200
1-2 months 200-600
2-5 months 50-200
6 months - 14 years 10-140
Adult male 24-336
Adult female 11-307

Health Implications

Low ferritin levels may indicate iron deficiency, which can lead to anemia. Symptoms might include fatigue, weakness, and pale skin. High ferritin levels could suggest iron overload, inflammation, or liver disease. Symptoms of iron overload may include joint pain, fatigue, and skin discoloration.By understanding ferritin and its role in iron storage, you can better monitor your health and discuss any concerns with your healthcare provider.

What does it mean if your Ferritin result is too high?

Hemochromatosis, a large buildup of iron in the body, can cause a very high ferritin blood level. In individuals with hereditary hemochromatosis, the daily absorption of iron from the intestines is greater than the amount needed to replace losses. Since the normal body cannot increase iron excretion, the absorbed iron accumulates in the body.

The excess iron deposits in the joints, liver, testicles, and heart, which causes damage to these organs and results in signs and symptoms of hemochromatosis. Some other diseases like alcoholism, thalassemia, and some types of anemia that cause red blood cells to be destroyed can also lead to hemochromatosis.

High ferritin levels may also be caused by Hodgkin’s disease, leukemia, infection, inflammatory conditions (such as arthritis or lupus), or a diet that is too high in iron. Symptoms of iron overload may include:

- Joint pain

- Fatigue / weakness

- Weight loss

- Lack of energy

- Abdominal pain

- Loss of sex drive

- Loss of body hair

- Heart problems such as congestive heart failure

-----------------------

Elevated ferritin levels, when all other iron markers (such as serum iron, total iron-binding capacity (TIBC), and transferrin saturation) are normal, can indicate several possible conditions. Ferritin is a protein that stores iron, and its levels can be influenced by factors other than iron status. Some possible reasons for elevated ferritin levels include:

  1. Inflammation or Infection: Ferritin is an acute-phase reactant, meaning its levels can increase in response to inflammation or infection. Conditions such as chronic inflammatory diseases (e.g., rheumatoid arthritis) or acute infections can raise ferritin levels.

  2. Liver Disease: Liver diseases, such as hepatitis, cirrhosis, or fatty liver disease, can lead to elevated ferritin levels because the liver plays a key role in storing and regulating iron.

  3. Malignancy: Certain cancers, particularly hematologic malignancies (like leukemia and lymphoma) and solid tumors, can cause elevated ferritin levels.

  4. Chronic Kidney Disease: Ferritin levels can be elevated in chronic kidney disease due to decreased clearance and increased inflammation.

  5. Metabolic Syndrome: Conditions associated with metabolic syndrome, such as obesity, insulin resistance, and type 2 diabetes, can be linked to elevated ferritin levels.

  6. Hemochromatosis: While typically associated with elevated iron markers, early stages or milder forms of hereditary hemochromatosis might present with high ferritin and normal other iron markers.

  7. Alcohol Consumption: Chronic heavy alcohol use can cause liver damage, leading to increased ferritin levels.

  8. Genetic Factors: Some people may have genetic predispositions to elevated ferritin levels without other iron overload indicators.

If elevated ferritin is detected, it is important for healthcare providers to consider these possibilities and potentially conduct further testing to determine the underlying cause.

What are potential options to decrease elevated Ferritin levels?

There are several potential options to decrease elevated ferritin levels:

1. Dietary changes:
   - Follow a low-iron diet, especially for those with hemochromatosis
   - Consume foods rich in phytic acid and polyphenols, which can reduce iron absorption (e.g. whole grains, vegetables)
   - Increase intake of green tea and coffee, which can inhibit iron absorption
   - Increase fiber intake
   - Limit alcohol consumption, as it can damage the liver and increase ferritin

2. Adopt a plant-based diet:
   - The Low Inflammatory Foods Everyday (LIFE) diet, rich in dark green leafy vegetables, was shown to reduce ferritin levels

3. Phlebotomy (blood removal):
   - For those with hemochromatosis, regular phlebotomy is recommended until ferritin falls to around 50 ng/mL

4. Address underlying conditions:
   - Treat any inflammatory conditions, liver disease, or metabolic disorders that may be causing elevated ferritin

5. Lifestyle changes:
   - Quit smoking, as it's associated with higher ferritin levels
   - Manage obesity, as it's a common cause of elevated ferritin

6. Avoid iron supplements and iron-fortified foods unless prescribed by a doctor

7. For mild elevations, observation over time may be appropriate under medical supervision

It's crucial to work with a healthcare provider to determine the underlying cause of elevated ferritin and develop an appropriate treatment plan. The approach may vary depending on the severity of elevation and any associated conditions.

What does it mean if your Ferritin result is too low?

Decreased levels of ferritin in the blood signify a reduced amount of iron stored in the body, which can lead to iron deficiency, the most common cause of anemia.

Ferritin acts as a cellular storage protein for iron, so its levels are a good indicator of the body's iron reserves. When these reserves are low, the body struggles to produce enough hemoglobin, a protein in red blood cells that enables them to carry oxygen. This condition can lead to iron deficiency anemia, characterized by symptoms such as fatigue, weakness, pale skin, shortness of breath, dizziness, and strange cravings for non-nutritive substances like ice or dirt, a condition known as pica.

The diagnosis of iron deficiency involves blood tests that measure ferritin, hemoglobin, and hematocrit levels, along with a complete blood count (CBC).

Causes of decreased ferritin levels include chronic blood loss (from heavy menstrual periods or internal bleeding), a diet insufficient in iron, an inability to absorb iron properly, and certain diseases that affect iron metabolism.

Treatment focuses on addressing the underlying cause of the iron deficiency and may include dietary changes to include more iron-rich foods, iron supplements, and, in some cases, intravenous iron therapy or treatment for conditions causing blood loss. For severe or persistent cases, a healthcare professional might investigate more deeply to rule out or treat underlying conditions contributing to the deficiency.
