Serum Iron Test

The Serum Iron Test measures the concentration of iron circulating in the blood. Iron is essential for producing hemoglobin, the protein in red blood cells that carries oxygen throughout the body.

This test helps healthcare professionals evaluate iron status and investigate possible iron deficiency or iron overload. It is often performed alongside other iron studies for a more complete assessment.

Why Is a Serum Iron Test Recommended?

• Iron Deficiency: Helps investigate low iron levels.
• Anemia Assessment: Supports the evaluation of certain types of anemia.
• Iron Overload: May help assess conditions associated with excess iron.
• Treatment Monitoring: May be used to monitor iron levels during treatment when clinically indicated.

Related Tests

Your healthcare professional may recommend additional tests, including:

• Serum Ferritin: Estimates the body’s stored iron.
• Total Iron-Binding Capacity (TIBC): Assesses the blood’s capacity to bind iron.
• Transferrin Saturation: Indicates the proportion of transferrin carrying iron.
• Complete Blood Count (CBC): Helps assess hemoglobin and red blood cell parameters.

Sample Requirements

• Sample type: Blood, typically serum.
• Fasting: Follow your laboratory’s instructions; morning collection or fasting may be requested because serum iron levels can vary throughout the day and after meals.
• Preparation: Inform your healthcare professional about iron supplements and medicines. Do not stop prescribed medication without medical advice.

Understanding Your Results

Low serum iron may occur with iron deficiency, chronic inflammation, or other conditions.

High serum iron may occur with iron overload, recent iron supplementation, or other medical conditions.

Serum iron levels alone cannot confirm iron deficiency or iron overload. Results should be interpreted alongside ferritin, TIBC or transferrin saturation, CBC findings, and clinical history.
