Part Description

LP18406-6   2-Methyl-3-Hydroxybutyrate
2-Methyl,3-Hydroxybutyric acid (HMBA) is involved in isoleucine catabolism and beta-oxidation of fatty acids and ketogenesis. HMBA is excreted in abnormally high amounts in beta-ketothiolase deficiency. PMID: 10755375 Source: Regenstrief LOINC, PMID: 10755375

Change Reason
Corrected typo by replacing comma between 'methyl' and '3' with a dash.; 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.
