What is the normal ammonia level range in the blood, and what does an elevated level indicate?

The normal ammonia level range in the blood is typically between 10 to 80 mcg/dL. An elevated level within this range can indicate liver disease, particularly conditions that could lead to hepatic encephalopathy, where the liver is unable to effectively remove ammonia from the bloodstream. This is critical because ammonia is a byproduct of protein metabolism, and its accumulation can have toxic effects on the brain.

In liver disease, the liver's capacity to process nitrogenous waste diminishes, leading to increased ammonia levels. This highlights the necessity of monitoring ammonia levels in patients with suspected liver dysfunction, as it can provide insights into the severity of the disease and the need for potential interventions.
