Therefore, the iron level drawn after ingestion may be deceptively low if measured after its peak. Iron is rapidly cleared from the serum and deposited in the liver. Levels above 500 micrograms/dL are associated with severe systemic toxicity. Levels between 350 to 500 micrograms/dL are associated with moderate toxicity. Peak serum iron levels below 350 micrograms/dL are associated with minimal toxicity. Sustained-release or enteric-coated preparation may have erratic absorption, and therefore a second level 6 to 8 hours post-ingestion should be checked. A serum iron level measured at its peak, 4 to 6 hours after ingestion, is the most useful laboratory test. ![]() Serum iron levels are used to determine a patient’s potential for toxicity. The diagnosis of iron toxicity is based on the history and clinical presentation.
