Doctor's Assessment Included

Every result includes a professional assessment from a BIG-registered doctor. For treatment decisions, discuss your results with your GP.

Minerals

Iron (Serum)

Serum iron fuels oxygen delivery to muscles and organs. Adequate levels support energy, endurance, and the stamina you need for an active lifestyle.

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

Low serum iron may be associated with fatigue, pale skin, weakness, dizziness, cold hands and feet, and difficulty concentrating.

High Levels

High serum iron may be associated with joint pain, fatigue, abdominal pain, and skin changes. Chronically elevated iron can damage organs and requires medical evaluation.

Recommendations

Male

If Low

Low iron may indicate iron deficiency anemia or blood loss. Consider iron supplementation and evaluation for GI bleeding.

If High

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.

Frequently Asked Questions

Why does serum iron fluctuate?
Serum iron levels can vary throughout the day, with meals, and due to recent iron intake. For the most accurate results, testing is typically done in the morning while fasting.
What is the difference between serum iron and ferritin?
Serum iron reflects current circulating iron, while ferritin indicates stored iron. Together, they give a more complete picture of your iron status.
Can diet alone correct low iron?
Mild deficiencies may improve with dietary changes, but significant deficiencies may require supplementation. Always consult your healthcare provider for appropriate guidance.
