Test Code ASB Arsenic, Blood
Ordering Guidance
The preferred method of screening for arsenic exposure is measurement of urinary arsenic concentration. Order either SPASU / Arsenic Speciation, 24 Hour, Urine or SPAS / Arsenic Speciation, Random, Urine.
Specimen Required
Patient Preparation: High concentrations of gadolinium and iodine are known to potentially interfere with most inductively coupled plasma mass spectrometry-based metal tests. If either gadolinium- or iodine-containing contrast media has been administered, a specimen should not be collected for 96 hours.
