Part Descriptions

LP15279-0   1-Methylhistidine
1-Methylhistidine is an amino acid metabolite and is a component of the dietary peptide anserine. Low levels may be due to inadequate methyl group transfer and result in low histidine levels. Methyl-transferase enzymes require Vitamin B12 and folate, so deficiencies in these may lead to decreased 1-Methylhistidine and histidine levels. Source: Regenstrief Institute

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.
