Iron poisoning is a medical emergency that occurs when someone ingests excessive amounts of iron-containing substances like supplements or multivitamins. It is caused by the accumulation of free iron in the bloodstream that damages the gastrointestinal tract, liver, and other vital organs. The Iron, Serum test is the most important test for diagnosis because it directly measures dangerously elevated iron concentrations in the blood.

Iron poisoning is caused by ingesting excessive amounts of iron-containing products, most commonly iron supplements, multivitamins with iron, or prenatal vitamins. Children are particularly vulnerable because they may mistake colorful iron tablets for candy and consume dangerous quantities. In adults, iron poisoning typically occurs from intentional overdose or accidental ingestion of large doses. Once absorbed, excess iron overwhelms the body's natural binding proteins and circulates as free iron, which generates harmful free radicals that damage cell membranes throughout the body.
The Iron, Serum test is the most important test for iron poisoning because it directly measures the concentration of iron circulating in your bloodstream, which becomes dangerously elevated after an overdose. This test confirms the diagnosis and helps emergency medical providers determine the severity of toxicity, which is critical for deciding whether treatments like whole bowel irrigation or chelation therapy with deferoxamine are necessary. Serum iron levels above 350-500 mcg/dL indicate serious toxicity, while levels exceeding 1000 mcg/dL represent life-threatening poisoning requiring immediate intensive treatment. Healthcare providers may also order additional tests like total iron-binding capacity (TIBC) and liver function tests to assess organ damage.
You should get tested immediately if you or someone you know has ingested a large amount of iron supplements or iron-containing vitamins, even if symptoms have not yet appeared. Seek emergency testing if you experience severe abdominal pain, vomiting (especially if the vomit contains blood or looks like coffee grounds), diarrhea with blood, or lethargy after taking iron pills. Children who have accidentally swallowed iron tablets need immediate testing regardless of the amount consumed, as even small overdoses can be dangerous for their smaller body size. Time is critical because iron poisoning progresses through stages, and early detection allows for interventions that can prevent permanent organ damage or death.
