Plasma Ammonia
Plasma ammonia is a byproduct of protein digestion that a healthy liver swiftly converts into harmless urea for kidney clearance.

Physiological Reference Ranges
The ranges below represent standard adult physiological values. Your laboratory's printed reference range always takes precedence.
11 – 55 µmol/L
11 – 48 µmol/L
15 – 55 µmol/L
What does a low result mean?
A low level is standard and optimal, proving that liver urea cycle clearance is working with high efficiency.
What does a high result mean?
A mild elevation is very often a pre-analytical artifact caused by sample tube transport without immediate ice chilling.
Questions ready for your doctor
Bring these questions to your next consultation to discuss with your healthcare practitioner:
- Was the sample kept strictly on ice during laboratory transport to prevent in-vitro ammonia release?
- Does this align reassuringly with my other liver enzymes (AST, ALT)?
- Is a confirmatory retest under strict cold protocol recommended?
