Frequently asked questions
- What is a normal Aldosterone level?
- A typical reference range for Aldosterone is 3–30 ng/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 Aldosterone measured in?
- Aldosterone is most commonly reported in ng/dL. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do Aldosterone 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 Aldosterone over time?
- Yes. Upload results from any lab and BloodId charts your Aldosterone over time against its reference range, so you can see whether the trend is rising, falling, or stable.
