Part Descriptions
LP14483-9 Carnitine esters
Esterified carnitine in blood. L-carnitine is essential for the transport of free fatty acids into mitochondria where fatty acids are oxidized from fat to produce energy. Low carnitine levels in skeletal muscle, liver, heart, and kidneys result in decreased ability of these tissues to utilize long chain fatty acids as an energy source. Low levels indicate muscle carnitine weakness or secondary carnitine deficiency associated with renal failure, cirrhosis, and many other defects.

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.
