Ferritin (Iron) Blood Test

Ferritin is also considered an acute-phase reactant, meaning its levels can increase in response to issues in the body, such as infections, autoimmune diseases, or cancer.

The blood in our body is composed of red blood cells, which are responsible for carrying oxygen to body tissues via the circulatory system. Red blood cells primarily contain a protein called haemoglobin, which is formed with the help of iron and ferritin. Iron is an essential mineral required by the body in small quantities daily. Iron deficiency occurs when the body lacks sufficient iron. This can lead to exhaustion and breathlessness due to reduced oxygen levels in the blood. Additionally, iron plays a vital role in muscle growth, as well as maintaining healthy hair and nails. Iron deficiency or anaemia can result in fatigue at work or home and has also been linked to increased heart palpitations.

Iron can only be absorbed through dietary intake. Consequently, individuals with poor dietary habits or certain medical conditions may be more prone to iron deficiency or anaemia. On the other hand, excessive iron levels can lead to iron toxicity. Maintaining the correct level of ferritin is therefore crucial.

At Welzo, our special Ferritin Blood Test can measure the levels of iron and ferritin in your blood. The results can help determine whether you need to consult a doctor, take iron supplements, or adjust your diet to ensure a healthy balance.

Symptoms of Iron Deficiency

If you experience one or more of the following symptoms, you may want to consider a ferritin blood test:

Dizziness or light-headedness

Severe exhaustion or frequent fatigue

Pale skin

Weakness

Rapid heartbeat or palpitations

Sore or inflamed tongue

Hair loss

Ferritin Blood Tests

Ferritin blood tests measure the amount of ferritin, a protein that stores iron, in your blood. Doctors may order a ferritin blood test if you exhibit signs or symptoms of iron deficiency, such as fatigue, weakness, or shortness of breath. This test may also be performed during anaemia treatment.

What is Ferritin?

Ferritin is a protein that stores iron in your cells. It is found in nearly every cell of the body, with the highest concentrations in the liver, bone marrow, and muscles. When the body needs iron, ferritin releases it into the bloodstream. Ferritin levels provide an indicator of how much iron is stored in your body.

The normal range for ferritin levels varies depending on age and sex. For adults, the typical range is between 20 and 400 nanograms per milliliter (ng/mL). If your ferritin level is below the normal range, your doctor may recommend treatment with iron supplements. Significantly elevated ferritin levels can indicate medical conditions such as hemochromatosis.

Understanding Ferritin Blood Test Results

Your doctor will interpret your ferritin blood test results alongside your symptoms and other lab tests. Low ferritin levels often indicate iron deficiency, while high ferritin levels may signal conditions like hemochromatosis. If you have concerns about your results, consult your doctor to discuss further testing or treatment options.

Importance of Addressing Iron Deficiency

Iron deficiency is the most common nutritional deficiency worldwide and a leading cause of anaemia. It is particularly prevalent among women of childbearing age, pregnant women, and young children. Symptoms of iron deficiency include fatigue, weakness, pale skin, and shortness of breath. Treatments range from dietary adjustments and supplements to injections.

If you suspect you may have iron deficiency, speak with your doctor. A blood test can confirm your iron levels, and your doctor can recommend appropriate treatments. For those with iron-deficiency anaemia, supplements or iron-rich foods may be prescribed.

Low Ferritin Levels and Anaemia

Low ferritin levels often indicate anaemia, a condition in which the body lacks sufficient red blood cells to carry oxygen effectively. This can result in fatigue, weakness, and pale skin. Monitoring ferritin levels is essential to track your response to anaemia treatments.

Types of Anaemia

There are several types of anaemia, each with distinct causes and symptoms. The most common type is iron-deficiency anaemia, which arises from insufficient iron levels. Other types include:

Sickle-cell anaemia: A hereditary condition where red blood cells are misshapen and unable to carry oxygen effectively.

Thalassemia: A genetic disorder affecting haemoglobin production.

Anaemia of chronic disease: Associated with conditions like cancer or kidney disease.

Pregnancy-related anaemia: Common due to increased iron demand during pregnancy.

Anaemia can also result from bleeding, such as gastrointestinal ulcers or heavy menstrual periods.

Conclusion

Anaemia is a serious condition but is often treatable. If you suspect you have anaemia, consult your doctor for a proper diagnosis and tailored treatment plan. For iron-deficiency anaemia, this may include dietary changes, supplements, or other interventions. Staying proactive about your health by monitoring ferritin levels and addressing symptoms early can help ensure optimal well-being.

A Ferritin (Iron) Blood Test measures the levels of ferritin in your blood, which helps assess your body’s iron stores and overall iron health.

The NHS provides Ferritin (Iron) Blood Tests based on eligibility criteria, consultations, and local guidelines.
