Part Descriptions

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

LP32035-5   Creatinine
Creatinine or creatine anhydride, is a breakdown product of creatine phosphate in muscle. The loss of water molecule from creatine results in the formation of creatinine. It is transferred to the kidneys by blood plasma, whereupon it is eliminated by glomular filtration and partial tubular excretion. Creatinine is usually produced at a fairly constant rate and measuring its serum level is a simple test. A rise in blood creatinine levels is observed only with marked damage to functioning nephrons; therefore this test is not suitable for detecting early kidney disease. Creatine and creatinine are metabolized in the kidneys, muscle, liver and pancreas.
