Arsenic (As) As (Arsenic) Cadmium (Cd) Cd (Cadmium) Hg (Mercury) Lead (Pb) Mercury (Hg) Pb (Lead) HMUOE
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.
Preferred screening test for detection of arsenic, cadmium, mercury and lead due to occupational exposure using random urine specimens
-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.
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.
