About this test

The Ammonia Test is a blood test used to measure ammonia levels in the body. It helps assess liver function and diagnose conditions related to ammonia buildup in the blood.

AMMONIA This Test measures the level of ammonia in the blood. Ammonia is a product formed during protein metabolism and is normally processed by the liver. Elevated levels may indicate liver dysfunction or problems in removing toxins from the body.

Conditions associated with this test:

  • Liver disease or liver failure

  • Hepatic encephalopathy

  • Urea cycle disorders

  • Kidney dysfunction

    The Ammonia Test is performed to:

    • Measure ammonia levels in the blood

    • Assess liver function

    • Help diagnose hepatic encephalopathy

    • Evaluate causes of confusion or altered mental state

    • Support the diagnosis of metabolic disorders

AMMONIA Test Purpose

This Test is performed to measure the level of ammonia in the blood. Primarily, the test is used to assess liver function and help diagnose hepatic encephalopathy, a condition in which impaired liver function causes ammonia to accumulate in the bloodstream and affect brain function. Additionally, it assists healthcare providers in evaluating individuals with symptoms such as confusion, altered mental status, excessive drowsiness, irritability, tremors, or coma. Furthermore, the test may be recommended to investigate inherited urea cycle disorders, particularly in newborns and children with unexplained neurological symptoms. Moreover, the results are interpreted alongside liver function tests, kidney function tests, neurological examination, and other laboratory findings to provide a comprehensive assessment.

  • Individuals with suspected hepatic encephalopathy.
  • Patients with chronic liver disease, cirrhosis, or liver failure.
  • People experiencing confusion, altered mental status, or unexplained drowsiness.
  • Individuals with unexplained neurological symptoms.
  • Newborns or children with suspected urea cycle disorders or inherited metabolic disorders.
  • Patients undergoing evaluation for acute liver failure.
  • Individuals with unexplained vomiting, lethargy, or seizures, especially in infants.
  • Patients requiring monitoring of liver disease progression or treatment response.
  • Anyone advised by their healthcare provider to assess blood ammonia levels.
