Frequently Asked Questions
Is fasting required for serum iron test?
Yes, fasting for 8-12 hours is recommended. Serum iron shows diurnal variation, peaking in the morning and declining through the day, so a fasting morning sample ensures accurate results.
What does serum iron measure?
It measures the amount of iron circulating in your blood bound to transferrin, the main iron transport protein. It reflects how much iron is available for red blood cell production.
What causes low serum iron?
Iron deficiency anemia, chronic blood loss, poor dietary intake, malabsorption disorders like celiac disease, and chronic kidney disease can all lower serum iron levels.
What causes high serum iron?
Iron overload conditions such as hemochromatosis, repeated blood transfusions, excessive iron supplementation, and certain liver diseases can raise serum iron.
Which medications affect serum iron results?
Iron supplements, oral contraceptives, aspirin, and chemotherapy drugs can alter iron levels. Inform your doctor about all medications before testing.
How is the sample collected?
A venous blood draw from the arm is collected in a serum separator tube. Results are typically available within 24 hours at Dr. Patho Labs.
