Tungsten/Creatinine [Mass Ratio] in 24 hour Urine
Active
Term Description
Analysis of tungsten levels in 24-hour urine collections is performed to determine exposure and accumulation of the toxic metal due to environmental or occupational (e.g. military) exposure or hazards. Toxic metals are reported as units per creatinine (e.g. ug/g{creat}) to account for urine dilution variations.
Part Descriptions
LP18123-7 Tungsten
A metallic element with the atomic symbol W, atomic number 74, and atomic weight 183.85. It is used in many manufacturing applications, including increasing the hardness, toughness, and tensile strength of steel; manufacture of filaments for incandescent light bulbs; and in contact points for automotive and electrical apparatus.

LP18123-7 Tungsten
Tungsten, also known as wolfram, is a hard, rare metal found in rocks and minerals and in numerous applications, including incandescent light bulb filaments, X-ray tubes, welding elctrodes, and golf clubs. It is also used in the military for armor-piercing munitions. Tungsten is released to the atmosphere by various mechanisms, including windblown dusts and during ore processing, tungsten alloy (hard-metal) fabrication, tungsten carbide production and use, and municipal waste combustion. Individuals who work in manufacturing, fabricating, and reclaiming industries may be exposed to higher levels of tungsten or tungsten compounds compared to the general population. Conditions such as pulmonary fibrosis, memory and sensory deficits, and increased mortality due to lung cancer have been attributed to occupational exposure to hard metals, including tungsten.

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.
