Test AvailabilityMon - Fri, business hours - urgent testing by arrangement
Turnaround Time1 - 7 days
Reference Interval

Normal non exposed level <0.47 umol/L

0 - 0.02 umoL/mmoL creatinine

Biological Exposure Index for inorganic arsenic and its methylated metabolites is 0.47 umol/L (35ug/L)

Workplace Exposure Standards 2018

Interpretation

Urine arsenic interpretation

If urine results are elevated (above the Biological Exposure Index), and it is unclear what the source of the potential exposure is, then the laboratory suggests the following protocol is followed:
 
Do a follow-up test at the end of a further working week, then re-test on the following Monday (after 48 hours of non-exposure coupled with avoidance of shellfish).  The expectation is that the concentration would halve and may fall under the recommended limit.
Shellfish avoidance should then continue.  Further testing at the end of the next working week should give a gauge of the effect of working practices and the requirement for any adjustments.
 
Note:  The half-life of arsenic is in the order of 48 hours.
Methyl compounds (eg DMA from shellfish) can contribute to reported inorganic arsenic levels.

 

Additional Information

The urine pottle used for specimen collection must be shown to be free of Arsenic contamination. Industrial samples collected at the end of working week. Inorganic arsenic levels are not affected by organic arsenic of dietary origin (i.e. fish). Urine Chromium can be done on the same sample.

 Please take a separate aliquot for creatinine
