-HMUOE / Heavy Metal Occupational Exposure, with Reflex, Random, Urine


Secondary ID

608893

Useful For

Detecting mercury toxicity due to occupational exposure in random urine specimens

Method Name

Only orderable as part of a profile. For more information see:

-HGUOE/ Mercury Occupational Exposure, Random, Urine

-HMUOE / Heavy Metal Occupational Exposure, with Reflex, Random, Urine

 

Triple-Quadrupole Inductively Coupled Plasma Mass Spectrometry (ICP-MS/MS)

Reporting Name

Mercury Occupational Exposure

Specimen Type

Urine

Specimen Minimum Volume

1.5 mL

Specimen Stability Information

Specimen Type Temperature Time Special Container
Urine Refrigerated (preferred) 7 days
  Frozen  7 days

Clinical Information

The correlation between the levels of mercury (Hg) excretion in the urine and the clinical symptoms is considered poor. However, urinary Hg is the most reliable way to assess exposure to inorganic Hg.

 

For more information, see HG / Mercury, Blood.

Reference Values

Only orderable as part of a profile. For more information see:

-HGUOE/ Mercury Occupational Exposure, Random, Urine

-HMUOE / Heavy Metal Occupational Exposure, with Reflex, Random, Urine

 

Biological Exposure Index (BEI): <35 mcg/g creatinine prior to shift

Cautions

To avoid contamination by dust, specimen should be collected away from the site of suspected exposure.
