Part Description

LP15331-9   Alanine
Alanine is a non-essential amino acid that exists as two distinct enantiomers: L-alanine and D-alanine. Alanine is one of the primary amino acids (secondary to leucine) used for protein construction. It is produced from pyruvate, exists in high levels in plasma, and is involved in the metabolism of sugar and organic acids.[PubChem: Alanine] Alanine acts as a substrate for alanine aminotransferase (ALT), an enzyme commonly measured to determine liver health. Increased alanine levels are seen in patients with lactic acidosis, carbamoyl phosphate synthetase deficiency, histidinemia, hyperprolinemia, and ornithine transcarbamylase deficiency. In patients with a mitochondrial disease, elevated alanine levels are primarily seen during times of physiologic stress or regression. PMID: 18243024 Source: Regenstrief LOINC

Change Reason
The PrThr property is used for LOINC terms whose results are reported using an ordered categorical scale, regardless of whether or not an internal threshold was used to make that determination. This change was approved by the Laboratory LOINC Committee in June 2016.
