What it measures
- Ammonia (NH3) — The main substance measured; high levels can mean the liver is not processing it well.
- Total blood ammonia — The overall amount of ammonia in the sample, reported in micrograms per deciliter (mcg/dL).
- Specimen quality note — Ammonia levels can rise if the sample is handled slowly, so the lab may comment on collection timing.
Preparation
No fasting is usually required, but your clinician may ask you to avoid a high-protein meal or certain medications before the draw. Follow any specific instructions you are given.
Results and what they mean
Results are reported as a number with a reference range, and your clinician interprets them alongside your symptoms, other liver tests, and medical history. A single result rarely tells the whole story. This is general information only and is not medical advice; discuss your results with a qualified clinician.
