Purpose
The Ferritin Blood Test measures the concentration of ferritin, a protein that stores iron in the blood. Ferritin levels reflect the amount of iron stored in the body.
This test is important because it helps assess iron status and detect conditions such as iron deficiency anemia or iron overload (hemochromatosis). It investigates the cause of fatigue, weakness, or abnormal blood counts.
The test can be done alongside Serum Iron, Total Iron-Binding Capacity (TIBC), Transferrin Saturation, Complete Blood Count (CBC), and C-Reactive Protein (CRP) or ESR.
These combined tests give a clearer picture of iron metabolism and overall health.
Patient Preparation
The patient should avoid taking biotin supplements for at least 72 hours before sample collection.
Samples
1ml with a minimum volume of 0.7ml of serum or plasma collected in a Gel-barrier, red-top, or green top tube (lithium heparin). Avoid using EDTA, oxalate, or citrate plasma. Transfer separated serum or plasma to a plastic transport tube if a red top tube is used. Store the sample at room temperature.
Reference Range
Male 1-9 years 12-124ng/ml, female 12-79ng/ml, adult male 30-400ng/ml, adult female 15-150ng/ml
Results Turnaround
Within 24 hours after sample collection.
Diseases / Diagnostic indicators
Abnormal ferritin levels can help diagnose various conditions related to iron metabolism. Elevated ferritin levels often point to iron overload disorders such as hemochromatosis, while low ferritin levels are a key indicator of iron deficiency anemia. It also plays a role in evaluating hypochromic microcytic anemia, where red blood cells are smaller and paler than normal due to low iron.
High ferritin levels may indicate:
- Hemochromatosis – a condition causing excess iron storage
- Liver disease, such as hepatitis or fatty liver
- Chronic inflammation or infection – ferritin acts as an acute-phase reactant
- Certain cancers or autoimmune diseases
Low ferritin levels typically suggest:
- Iron deficiency anemia – the most common cause of low ferritin
- Chronic blood loss – from ulcers, heavy menstruation, or gastrointestinal bleeding
- Poor dietary iron intake
Ferritin results are interpreted alongside other iron studies to determine the cause and guide treatment. For more on the Ferritin Blood Test, read this study.
