Note: The normal range may vary among different laboratories. Consult your healthcare provider about your specific test results.
Deviation from normal levels indicates the following:
A. Increased levels of amino acids may indicate:
- Fructose intolerance
- Ketoacidosis (from diabetes)
- Eclampsia
- Inborn error of metabolism
- Kidney failure
- Reye syndrome (rare disorder affecting liver and brain, often post-viral infection)
B. Decreased levels of amino acids may indicate:
- Inborn error of metabolism
- Adrenal cortical hyperfunction (excessive production of adrenal gland hormone)
- Hartnup disease (genetic disorder impairing amino acid absorption in the intestine)
- Huntington chorea (inherited neurodegenerative disorder)
- Malnutrition
- Nephrotic syndrome
- Phlebotomus fever (vector-borne disease transmitted by sandflies)
