Laboratory assay overview

Amino acid analysis is necessary for the diagnosis of a variety of inborn errors of metabolism. These include, but are not limited to, Phenylketonuria, Tyrosinemia, Citrullinemia, Non-Ketotic Hyperglycinemia, Maple Syrup Urine Disease, and Homocystinuria. The assay is also key for the continued monitoring of treatment plans for these disorders and useful for assessing nutritional status of patients. Our methodology is highly accurate at very low levels as well as at elevated levels.

Laboratory assay overview

Diagnosis and monitoring of inherited aminoacidurias. Most notably, quantitation of amino acids in CSF is useful in the diagnosis of glycine encephalopathy. CSF samples are most informative when a plasma sample is collected at the same time and ratios of the amino acid concentrations in CSF to plasma are calculated.

Verify these ranges and sources

We compile every detail above directly from named laboratory directories and published clinical studies. Laboratories calculate standard reference intervals from the statistical distribution of tested populations for a specific assay method and demographic group, rather than setting universal optimal targets.
