In any case, hyperammonemia is generally defined as ammonia levels greater than 50 μmol/L in adults and greater than 100 μmol/L in newborns. [2] [4] These values should be considered as decision limits and the normal reference ranges of individual laboratories should be used for clinical interpretation. [4]
More specifically, optimal levels are generally close to a central tendency of the values found in the population. However, usual and optimal levels may differ substantially, most notably among vitamins and blood lipids, so these tables give limits on both standard and optimal (or target) ranges.

Adults with high blood ammonia levels: disorientation, confusion, slurred speech, unusual and extreme combativeness or agitation, stroke-like symptoms, lethargy and delirium. Many may be seen by neurologists or psychiatrists because of psychiatric symptoms, including schizophrenia and bipolar disorder.
[2] [6] It may be supported by blood ammonia levels, an electroencephalogram, or computer tomography (CT scan) of the brain. [4] [6] Hepatic encephalopathy is possibly reversible with treatment. [1] This typically involves supportive care and addressing the triggers of the event. [4] Lactulose is frequently used to decrease ammonia levels. [1]
The comprehensive metabolic panel, or chemical screen (CMP; CPT code 80053), is a panel of 14 blood tests that serves as an initial broad medical screening tool. The CMP provides a rough check of kidney function, liver function, diabetic and parathyroid status, and electrolyte and fluid balance, but this type of screening has its limitations.

Diagnosis is based mainly on clinical findings and laboratory test results. Plasma concentrations of ammonia (>150 μmol/L) and citrulline (200-300 μmol/L) are elevated. Elevated levels of argininosuccinic acid (5-110 μmol/L) in the plasma or urine are diagnostic. Molecular genetic testing confirms diagnosis.
