26285 Heavy Metal Occupational Exposure, with Reflex, Random, Urine (HMUOE)

Heavy Metal Occupational Exposure, with Reflex, Random, Urine (HMUOE)
Test Code: HMUOESO
Synonyms/Keywords

​Arsenic (As)
As (Arsenic)
Cadmium (Cd)
Cd (Cadmium)
Hg (Mercury)
Lead (Pb)
Mercury (Hg)
Pb (Lead)
HMUOE

Test Components

​Arsenic, Cadmium, Mercury, Lead

If arsenic concentration is greater than or equal to 10 mcg/L, then speciation will be performed at an additional charge.

Useful For

​Preferred screening test for detection of arsenic, cadmium, mercury and lead due to occupational exposure using random urine specimens

Specimen Requirements
Specimen TypePreferred Container/TubeAcceptable Container/TubeSpecimen VolumeSpecimen Minimum Volume
(allows for 1 repeat)
Pediatric Minimum Volume
(no repeat)
​Random Urine​Clean, plastic urine container with no metal cap or glued insert​6 mL​3 mL
Collection Processing Instructions

-Patient should not eat seafood for a 48-hour period prior to start of collection.

-High concentrations of gadolinium and iodine are known to interfere with most metals tests. If either gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.

Specimen Stability Information
Specimen TypeTemperatureTime
​Urine ​​Refrigerated (preferred)​7 days
​Frozen​7 days
Rejection Criteria
All specimens will be evaluated at Mayo Clinic for test suitability.
Interference

Consumption of seafood before collection of a urine specimen for arsenic testing is likely to result in a report of an elevated concentration of arsenic found in the urine, which can be clinically misleading.

Nitric acid cannot be added to either the collection or aliquot container. Nitrate interferes with the extraction procedure that would need to take place in the event of a positive arsenic result.
