Part Descriptions

LP16802-8   Arsenic
Arsenic (As, CAS No. 7440-38-2) is a metalloid that exists in both inorganic and organic forms in the environment and is classified as a human carcinogen by the U.S. EPA (Environmental Protection Agency) and IARC (International Agency for Research in Cancer). Arsenic levels are naturally higher in certain geographical areas, including regions of Asia, China, Chile, Mexico and United States. PMID: 27894683 Exposure to toxic levels of arsenic, mainly via ingestion of As contaminated water and food, occur in these areas as well as near hazardous waste sites or in the workplace. Chronic exposure to low level of arsenic can cause skin lesions (e.g. melanosis, leucomelanosis, and keratosis), neurological effects, high blood pressure, diabetes mellitus, cardiovascular and respiratory diseases, and cancers typically involving the skin, lung, and bladder. PMID: 19190988 High exposure levels to arsenic can cause death.

Veterinary Medicine:
Arsenic is seldom reported since the concentrations normally found in animal feeds are significantly less than the toxic dietary concentration. If arsenic poisoning occurs, signs of intoxication include reduce feed intake and depressed growth. Some animal species can have convulsions and incoordination followed by posterior paresis and quadriplegia, blindness and decreased hemoglobin. In pigs, cases of arsenic poisoning usually arise from the use of organic arsenical growth-promoting feed additives. 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.
