May be useful for the detection of recent (<24 hours after exposure) and/or large dose arsenic exposures. For acute or chronic exposure, Arsenic, Urine with Reflex to Fractionated (0025000) is preferred.
Quantitative Inductively Coupled Plasma-Mass Spectrometry
Diet, medication, and nutritional supplements may introduce interfering substances. Patient should be encouraged to discontinue nutritional supplements, vitamins, minerals, and non-essential over-the-counter medications (upon the advice of their physician) and avoid shellfish and seafood for 48 to 72 hours.
Royal blue (K2EDTA or Na2EDTA).
Transport 7 mL whole blood in the original collection tube. (Min: 0.5 mL)
Room temperature. Also acceptable: Refrigerated.
Specimens collected in tubes other than Royal Blue (EDTA). Specimens transported in containers other than Royal Blue (EDTA) tube or Trace Element-Free Transport Tube. Heparin anticoagulant. Clotted specimens.
Trace Elements requisition form may be required (ARUP form #32990).
Ambient: Indefinitely; Refrigerated: Indefinitely; Frozen: Unacceptable
Elevated results may be due to skin or collection-related contamination, including the use of a noncertified metal-free collection/transport tube. If contamination concerns exist due to elevated levels of blood arsenic, confirmation with a second specimen collected in a certified metal-free tube is recommended.
Potentially toxic ranges for blood arsenic: Greater than or equal to 600 µg/L.
Blood arsenic is for the detection of recent exposure poisoning only. Blood arsenic levels in healthy subjects vary considerably with exposure to arsenic in the diet and the environment. A 24-hour urine arsenic is useful for the detection of chronic exposure.
