Frequently asked questions
- What is a normal Iron level?
- A typical reference range for Iron is 60–170 µg/dL (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is Iron measured in?
- Iron is most commonly reported in µg/dL. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do Iron reference ranges come from?
- BloodId uses ABIM standard reference ranges and educational information from MedlinePlus (see our methodology). Reference ranges still vary by lab, age, and sex, so always compare against your own report.
- Can I track Iron over time?
- Yes. Upload results from any lab and BloodId charts your Iron over time against its reference range, so you can see whether the trend is rising, falling, or stable.
