LP18136-9   2-Methylcitrate
2-Methylcitrate (methylcitric acid (MCA)) is measured as a second-tier assay when abnormal propionyl carnitine or methionine concentrations are identified in a primary newborn screen. Methylmalonic acidemia (MMA) and propionic acidemia (PA) are defects of propionate metabolism caused by deficiencies in methylmalonyl-CoA mutase and propionyl-CoA carboxylase, respectively. The clinical phenotype of both conditions includes vomiting, hypotonia, lethargy, apnea, hypothermia, and coma in the newborn period, and both MMA and PA are associated with elevated MCA and propionyl carnitine concentrations. MMA and PA can be distinguished based on methylmalonic acid concentration, which is elevated in MMA and normal in PA. Source: Regenstrief LOINC

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.
