ACE (Angiotensin-Converting Enzyme)
Angiotensin-Converting Enzyme (ACE) is an enzyme primarily produced in the lungs that converts angiotensin I into the active angiotensin II. ACE blood testing is most commonly used to help diagnose a…

Also known as: ace, angiotensin converting enzyme, angiotensin-converting enzyme, sace, serum ace, Angiotensin I converting enzyme, Kininase II, Peptidyl dipeptidase A
Reference range: 8–53 U/L (Source: ABIM)
Standard unit: U/L
High values may indicate
High ACE levels may indicate active sarcoidosis, Gaucher disease, hyperthyroidism, or certain liver and lung conditions.
Low values may indicate
Low ACE levels often occur with use of ACE inhibitor medications and may also be seen in advanced lung disease; low values can also be normal.
Frequently asked questions
- What is a normal ACE (Angiotensin-Converting Enzyme) level?
- A typical reference range for ACE (Angiotensin-Converting Enzyme) is 8–53 U/L (source: ABIM). Reference ranges vary by laboratory, age, and sex, so always compare against the range on your own lab report.
- What units is ACE (Angiotensin-Converting Enzyme) measured in?
- ACE (Angiotensin-Converting Enzyme) is most commonly reported in U/L. Labs in different countries may use other units — you can convert between them with BloodId's blood test unit converter.
- Where do ACE (Angiotensin-Converting Enzyme) 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 ACE (Angiotensin-Converting Enzyme) over time?
- Yes. Upload results from any lab and BloodId charts your ACE (Angiotensin-Converting Enzyme) over time against its reference range, so you can see whether the trend is rising, falling, or stable.
