Part Descriptions

LP18431-4   Carnitine.free (C0)
Carnitine.free is a primary marker for carnitine uptake defect, propionic acidemia, maternal carnitine uptake defect, carnitine palmitoyltransferase I deficiency and primary lactic acidemia (various types). It is also a secondary marker for maternal glutaric acidemia type I. 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.
