Doctor's Assessment Included
Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.
Iron (Serum)
Serum iron indicates current iron availability for oxygen transport during exercise. Low levels can directly impact aerobic performance and recovery time.
What It Measures
This test measures the amount of iron bound to transferrin in your blood at the time of testing. It reflects your current iron availability rather than long-term stores.
Why It Matters
Iron is vital for producing red blood cells and carrying oxygen. Both low and high levels can affect your health. Serum iron is best interpreted alongside ferritin and TIBC for a complete picture. Consult your healthcare provider.
When to Test
Testing may be recommended if you experience fatigue, weakness, or shortness of breath. It is often part of an iron studies panel when evaluating anaemia or iron metabolism disorders.
Symptoms
Low Levels
High Levels
Recommendations
Male
Low iron may indicate iron deficiency anemia or blood loss. Consider iron supplementation and evaluation for GI bleeding.
High iron may indicate hemochromatosis or excessive supplementation. Consider genetic testing and reduce iron supplement intake.
Female
Low iron is common in women due to menstruation. Consider iron supplementation (25-50 mg daily) with vitamin C for better absorption.
High iron may indicate hemochromatosis or excessive supplementation. Consider genetic testing and reduce iron supplement intake.
Lifestyle Tips
Eat a balanced diet with iron-rich foods. Pair plant-based iron with vitamin C for better absorption. Avoid excessive iron supplementation without medical guidance, as too much iron can be harmful.
