Ammonium in plasma

We remind you that independent interpretation of the results is unacceptable, the information provided below is for reference purposes only.

Ammonia is a laboratory test that measures the concentration of ammonia in plasma. Ammonia is produced during the breakdown of proteins and is normally converted into urea in the liver. The test is used to assess liver function, metabolic disorders, and certain neurological conditions.

Indications

The test is recommended in cases of:

• suspected liver failure
• hepatic encephalopathy
• acute and chronic liver diseases
• liver cirrhosis
• urea cycle disorders
• altered mental status
• confusion, drowsiness, or disorientation
• unexplained seizures
• monitoring patients with severe liver disease

Procedure

• Venous blood sample collection under special laboratory conditions
• The sample must be processed quickly to avoid result alteration
• The analysis is performed using biochemical methods
• The procedure takes only a few minutes
• Results are usually available the same day or within 1 working day

Interpretation of Results

• Elevated ammonia level:
  • may indicate impaired liver function
  • occurs in liver failure and hepatic encephalopathy
  • may be associated with inherited metabolic disorders
  • can cause neurological symptoms
• Decreased ammonia level:
  • is rare
  • usually has no significant clinical relevance

Clinical Significance

• Ammonia is an important indicator of protein metabolism and liver function
• Increased levels may have toxic effects on the central nervous system
• The test is useful in diagnosing and monitoring hepatic encephalopathy
• Results should always be interpreted together with clinical findings and other laboratory tests

IMPORTANT!

It is essential to remember that the information provided in this section is not intended for self-diagnosis or self-treatment. If you experience any symptoms or a condition worsens, it is crucial to consult a healthcare professional for proper diagnosis and treatment. Only a qualified specialist can accurately diagnose and determine the appropriate course of action. For the most accurate and consistent evaluation of test results, it is recommended to have them performed at the same laboratory. This is because different laboratories may use varying methods and units of measurement for similar tests.
