Part Descriptions

LP15097-6   5-Hydroxyindoleacetate
5-hydroxyindoleacetate (5HIAA) is a metabolite of serotonin and is excreted in the urine. Serotonin is produced in large amounts by carcinoid tumors. Carcinoid tumors are rare, slow-growing tumors usually found in the lining of the digestive tract or in the lungs. The serotonin that is released by the carcinoid tumors is metabolized by monoamine oxidase in the liver, lungs, and brain to 5HIAA. Testing for elevated levels of 5HIAA in 24 hour urine specimens is 73% sensitive and 100% specific for the diagnosis of carcinoid tumors. A fasting plasma 5HIAA correlates to a urine 5HIAA and other relevant biomarkers.

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.
