Search Links: General Info : Protocols : LabTestsOnline

DescriptionUrine is the preferred sample type for assessing exposure to arsenic. Inorganic arsenic is rapidly eliminated from the blood. A low blood arsenic concentration cannot exclude clinically significant exposure. Please see tests and tubes entry for Arsenic (urine).
IndicationPlease request urine arsenic as a first line test if exposure to arsenic is suspected.
Additional InfoProlonged exposure in arsenicals in fruit sprays, weed killers, rat poisons, industrial compounds (copper, lead & zinc smelting). Symptoms: characteristic skin pigmentation, weakness, malaise, GI bleeding. Pathology: arsenic binds to sulphydryl groups interfering with enzymatic processes
Concurrent Testsna
Dietary Requirementsna
InterpretationTotal blood arsenic concentration may be elevated following fish consumption due to the presence of the non-toxic arsenic compound arsenobetaine. It is not possible to separate the arsenic species in a blood sample to determine the source of exposure. Please request urine arsenic as the first line test as this will give more information regarding the source of exposure.
