Iron
What It Is
Serum iron measures the amount of iron circulating in the blood, bound to transferrin.
Why It Matters
Iron is essential for oxygen transport. Both deficiency and overload can have significant health consequences.
If Levels Are High
Elevated serum iron may indicate haemochromatosis, liver disease, or excessive supplementation.
If Levels Are Low
Low iron is a common cause of anaemia, particularly in menstruating women and those on restrictive diets.
Preparation
Morning fasting sample preferred for accuracy.
How Often to Test
Annually, or more often if at risk of iron deficiency or overload.
