How to use Iron Status Guide
Interpret ferritin, hemoglobin, and transferrin saturation with deficiency risk and dietary/ supplementation guidance.
Choose measurements that describe your actual session or situation, confirm the units, then calculate. Read the result alongside its assumptions and use the tool again when your inputs change.

How to interpret the output
Screening outputs are informational, not a diagnosis. Discuss concerning symptoms or measurements with an appropriate clinician.
Repeat measurements using similar conditions when monitoring trends. Numerical predictions can vary with input accuracy, measurement method and individual circumstances.
Limitations and responsible use
Iron status interpretation requires clinical context. Do not supplement iron without testing — iron overload is dangerous. Consult a physician.

What does the Iron Status Guide estimate?
Interpret ferritin, hemoglobin, and transferrin saturation with deficiency risk and dietary/ supplementation guidance.
Which information do I need for this health tool?
Provide Ferritin (ng/mL), Hemoglobin (g/dL), Transferrin saturation (%), Sex, Age, and any additional fields shown above. Use your own relevant measurements and the units indicated in each field.
How should I interpret the result?
Screening outputs are informational, not a diagnosis. Discuss concerning symptoms or measurements with an appropriate clinician. Compare results with your goals and other relevant observations rather than using a single output to make a major decision.
