An Iron (Total) test measures the amount of iron circulating in your blood bound to transferrin protein. This test is part of evaluating iron status and diagnosing the cause of anemia.
What This Test Measures
Serum Iron:
The amount of iron bound to transferrin in your blood. Iron is essential for producing hemoglobin and carrying oxygen. Serum iron levels fluctuate throughout the day and with meals.
Reference Ranges
• Men: 65-175 mcg/dL
• Women: 50-170 mcg/dL
Who Should Consider This Test
• Symptoms of iron deficiency (fatigue, weakness, pale skin)
• Evaluating the cause of anemia
• Suspected iron overload (hemochromatosis)
• Monitoring iron supplementation
• Heavy menstrual periods
• Chronic fatigue
Limitations of Serum Iron Alone
Serum iron can vary significantly based on:
• Time of day (higher in morning)
• Recent meals (especially iron-rich foods)
• Inflammation (lowers iron even with adequate stores)
• Supplements taken recently
For complete iron assessment, ferritin and TIBC are recommended alongside serum iron.
