|Test Code||ARS24 / 007039L|
|Test||ARSENIC EXPOSURE PROFILE, URINE|
|Methodology||Total: Inductively Coupled Plasma-Mass Spectrometry (ICP-MS)
Inorganic: Flow Injection Atomic Absorption Spectrometry (FIAS)
|Description||Useful as a monitor of chronic exposure to arsenic|
|Specimen||5 mL (minimum volume: 2.5 mL) from a random or 24 hour urine collection. Sampling time is the end of the work week for industrial exposure monitoring. Avoid contact with metal during collection. Send urine at room temperature in a plastic urine container with no preservative.
NOTE: Patient must avoid all seafood for 72 hours prior to collection. Seafood consumption two to three days prior to specimen collection can markedly elevate levels of total arsenic in urine. This dietary form of arsenic is nontoxic and is comprised primarily of arsenobetaine and arsenocholine. Inorganic arsenic is used for industrial exposure monitoring.
|Reference Values||Environmental exposure:
Total: 0 - 50 µg/L (0 - 50 µg/24 hours)
Inorganic: < 20 µg/L
BEI® (sampling time is end of workweek): 35 µg/g creatinine
|Analytic Time||1 Day|
|Day(s) Test Set Up||Monday through Friday|
