Xanthine/Creatinine [Molar ratio] in Urine

Part Descriptions

LP15953-0 Xanthine
A purine base found in most body tissues and fluids, certain plants, and some urinary calculi. It is an intermediate in the degradation of adenosine monophosphate to uric acid, being formed by oxidation of hypoxanthine. The methylated xanthine compounds caffeine, theobromine, and theophylline and their derivatives are used in medicine for their bronchodilator effects. (Dorland, 28th ed) Source: National Library of Medicine, MeSH 2006

LP15953-0 Xanthine
Xanthine is a product on the pathway of purine degradation and is converted to uric acid by the action of the xanthine oxidase (xanthine dehydrogenase) enzyme. Some people lack sufficient xanthine oxidase, and thus xanthine cannot be converted to uric acid. This rare genetic disorder is called xanthinuria results from excessive excretion of xanthine into the urine. This disorder can result in urolithiasis and sometimes myopathy from xanthine deposition. Elevated xanthine can also result from allopurinol treatment. Xanthine is also the core chemical component of a group of alkaloids that are commonly used for their effects as mild stimulants and as bronchodilators, notably in treating the symptoms of asthma. Their effects, however, are widespread and their therapeutic range is narrow and so they are not the drug of choice in asthma treatment. Methylated xanthine derivatives include caffeine, theophylline, and theobromine (found mainly in chocolate). These drugs inhibit phosphodiesterase and antagonise adenoine. 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.
