Amino Acid Analysis, Plasma

This test quantitatively measures amino acids in plasma to detect abnormalities associated with inborn errors of metabolism such as amino acidurias. Disturbances of amino acid metabolism may be suspected in infants or children who have feeding abnormalities, growth failure, development failure, seizures, unexplained acidosis (uncommon), elevated blood ammonia.

Argininemia, Homocystinuria, Maple syrup urine disease, Phenylketonuria (PKU)

Clinical Information

Amino acids are components of all of the body’s proteins, both enzymatic and nonenzymatic. Any abnormality in the metabolism of amino acids may lead to intellectual disabilities or other problems. Treatments are available for some amino acid disorders which can help prevent the disabilities and other symptoms.

Technical Information

Amino acids are measured using an amino acid analyzer (ion exchange chromatography).

Specimen Requirements

  • Plasma is the accepted sample type for this test. A minimum of 3 mL whole blood collected in a sodium heparin tube.
  • Or, blood can be centrifuged and a minimum of 1 mL plasma removed and sent for analysis.

Transport Instructions

  • Plasma should be frozen after collection and shipped frozen, preferably on dry ice.
  • Whole blood should be shipped at ambient temperature.
