Collection Guidelines

Specimen cannot be collected for 48 hours if either gadolinium or iodide containing contrast media has been administered.

Reference Range

See reference lab report

Limitations and Contraindications

High concentrations of gadolinium and iodine are known to interfere with most metals tests. If either media has been administered, do not collect specimen for 96 hours. Blood is not a good specimen to screen for arsenic. Test is not useful for evaluation of chronic arsenic exposure.

Interpretation

Abnormal blood concentrations >12 ng/mL indicate significant exposure. Absorbed arsenic is rapidly distributed into tissue storage sites with a blood half-life of <6 hours. Unless a blood specimen is drawn within 2 days of exposure, arsenic is not likely to be detected in a blood specimen

Additional Information

Arsenic is also included in Heavy Metals Screen
