Iron Panel: What Your Iron Studies Mean
An iron panel provides a comprehensive picture of your body's iron status. Iron deficiency is the most common nutritional deficiency worldwide, affecting over 2 billion people. The panel distinguishes between iron deficiency, iron deficiency anemia, and iron overload.

What It Tests
Serum iron, ferritin, TIBC (Total Iron Binding Capacity), transferrin saturation, and sometimes soluble transferrin receptor.

Why It's Ordered
Iron panels are ordered to diagnose iron deficiency anemia, monitor iron supplementation therapy, screen for hemochromatosis (iron overload), and investigate unexplained fatigue or anemia.

Frequently Asked Questions
What pattern of results confirms iron deficiency? expand_more
Low ferritin is the earliest sign. Full iron deficiency shows low ferritin, low serum iron, high TIBC, and low transferrin saturation (below 20%).
What is hemochromatosis? expand_more
Hereditary hemochromatosis is a genetic condition causing the body to absorb too much iron from food. It can damage the liver, heart, pancreas, and joints if untreated.
Should I fast for an iron panel? expand_more
Yes — fast for 8–12 hours and test in the morning for the most accurate serum iron results. Ferritin can be tested without fasting.
Can I take iron supplements before an iron test? expand_more
No — stop iron supplements 24 hours before testing as they significantly raise serum iron levels and can give a false normal result.
