ARS24 / 007039L
ARSENIC EXPOSURE PROFILE, URINE

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 g/L (0 - 50 g/24 hours)
Inorganic: < 20 g/L
Occupational exposure:
BEI (sampling time is end of workweek): 35 g/g creatinine 
Analytic Time 1 Day 
Day(s) Test Set Up Monday through Friday 
CPT Code(s) 82175  Arsenic
