Part Descriptions

LP14463-1   Metanephrine
Metanephrine is a metabolite generated when epiniphrine is cleaved by catechol O-methyltransferase. It is also known as 4-hydroxy-3-methoxy-alpha-((methylamino)methyl) benzenemethanol with formula C10-H15-N-O3. Copyright Text is available under the Creative Commons Attribution/Share-Alike License.

LP14463-1   Metanephrine
Extra-neuronal catechol-o-methyl transferase (COMT) metabolite of the catecholamine epinephrine. Measurement of plasma metanephrines is more sensitive (but may be less specific) than measurement of catecholamines for the detection of neuroblastoma and pheochromocytoma.

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.
