Select link for collection requirements. Both samples should be collected simultaneously.
Requisition/Form:Submit request using Biochemical Genetics Laboratory Requisition.
Please ensure all required information, including patient's clinical history/indication, is provided on the requisition.
Order Restrictions:This test is considered specialty testing; this test will be cancelled if sufficient clinical justification is not provided.
Indications:This test is for the investigation of disorders of amino acid metabolism with specific neurologic presentations (e.g., nonketotic hyperglycinemia, serine biosynthesis disorders, GABA transaminase deficiency).
Method:Amino acids are detected using an Amino Acid Analyzer with internal standard.
