Ferritin, found in specific cells, reflects total body iron stores. As a storage form of iron, ferritin binds and releases iron in a controlled manner, buffering against deficiency or overload. Iron plays vital roles in metabolism, cell formation, energy production, oxygen transport, bone marrow function, and muscle health. Ferretin's serum concentration indicates iron status. The test is crucial for diagnosing conditions like iron deficiency anaemia, where levels drop to 1/10th of normal, or iron overload diseases like hemochromatosis, where levels rise.

Reasons for Undergoing the Ferritin Test
The ferritin test is a valuable diagnostic procedure used to measure the levels of ferritin, a protein that stores iron in the body. This test plays an essential role in identifying imbalances in iron levels, which can be critical for maintaining overall health. Whether to investigate symptoms of iron-related conditions, monitor specific diseases, or evaluate the effectiveness of treatment, the ferritin test provides key insights into the body's iron reserves. Here are some common reasons why your healthcare provider may recommend a ferritin test:
- To investigate symptoms of iron deficiency or overload, such as fatigue, weakness, or joint pain
- To diagnose and monitor iron deficiency anaemia
- To determine if iron deficiency contributes to restless legs syndrome (RLS) symptoms
- To help diagnose liver conditions like cirrhosis, hepatitis B, or hepatitis C
- To monitor your response to iron supplementation
- To regularly assess iron levels in individuals with chronic conditions like cancer or kidney disease
- To screen high-risk groups for iron deficiency, such as pregnant women or those with poor diets
List of Parameters Considered During the Ferritin Test
The ferritin test is a vital diagnostic tool used to assess the iron levels in your body by measuring the amount of ferritin, a protein responsible for iron storage, in your blood. This test helps evaluate whether your body has adequate, deficient, or excessive iron, offering insights into your overall health. Here's what the test considers:
- Ferritin Levels: The serum ferritin test measures the amount of ferritin in your blood, reflecting the total iron stored in your body. Normal levels range from 30-400 ng/mL for males and 13-150 ng/mL for females. High levels may indicate iron overload, inflammation, or liver disease, while low levels suggest iron deficiency anaemia.
