New Question

is initial ammonia level accurate for diagnosing hepatic encephalopathy?

Answer

Measuring initial ammonia levels alone is not sufficient for accurately diagnosing hepatic encephalopathy (HE).

Serum ammonia levels

Diagnosis of HE

Neurophysiological and psychometric tests

Differential diagnosis

In conclusion, while serum ammonia levels can aid in the diagnosis of HE, they are not sufficient on their own. A comprehensive approach including clinical criteria, exclusion of other causes, and neurophysiological and psychometric tests is recommended for accurate diagnosis.
