🩸 Ferritin & Iron Stores Analyzer
How this ferritin checker works
Enter the ferritin value from your blood test in ng/mL (this is the same number as µg/L) and choose your sex. The tool places the value in one of four bands: below 30 ng/mL (iron stores likely depleted), 30–50 (borderline), within the usual range, or above about 150 ng/mL for women / 300 ng/mL for men (raised).
Why ferritin can mislead
Ferritin rises with inflammation, infection, liver disease and some other conditions, so a normal or high value does not always mean iron stores are full. This tool cannot adjust for that. Your doctor may also look at haemoglobin, transferrin saturation and CRP.
Important
This is an educational check, not a diagnosis. Do not start or stop iron supplements based on this tool — iron overdose is harmful. Always discuss your results with a doctor.
