Written by Private MD Labs Medical Writing Team • Last Updated: September 8, 2025
Iron poisoning is a serious medical emergency that occurs when someone ingests excessive amounts of iron-containing substances, such as iron supplements or multivitamins. This condition can cause severe damage to the gastrointestinal tract, liver, and other vital organs, making prompt diagnosis and treatment critical.
Recommended Test
Iron, Serum
This test directly measures the concentration of iron in the blood serum, which becomes dangerously elevated following iron poisoning. High serum iron levels confirm the diagnosis and help healthcare providers assess the severity of toxicity, enabling them to initiate appropriate emergency treatment to prevent serious organ damage to the gastrointestinal tract, liver, and other vital organs.

Diagnosing Iron Poisoning
While the diagnosis of iron poisoning begins with a thorough history of exposure and clinical symptoms, blood testing is essential to confirm dangerous iron levels in the bloodstream. Measuring serum iron levels provides healthcare providers with crucial information to assess the severity of poisoning and guide immediate treatment decisions.
Understanding Iron Toxicity
Iron poisoning typically occurs in phases, starting with gastrointestinal symptoms and potentially progressing to systemic toxicity. Elevated serum iron levels can indicate the body's inability to properly regulate iron absorption, leading to free iron accumulation that damages cellular structures throughout the body.
Important Considerations
