Answer

The workup for iron toxicity includes the following studies:

  • Serum iron

  • Glucose

  • Complete blood count (CBC)

  • Serum lactate

  • Arterial blood gas (ABG) - To assess for metabolic acidosis

  • Serum electrolytes - For anion gap calculation

  • Renal function tests

  • Liver function tests (LFTs)

  • Coagulation studies

  • Lipase and amylase levels - Occasional patients experience pancreatic injury

  • Pregnancy test in women of childbearing age

  • Blood type and cross-matching

  • Ferritin levels - Helpful for diagnosing chronic toxicity; levels may exceed 1000 mcg/L
