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.
Collect
Royal blue (K2EDTA) or royal blue (NaHep).
Additional Requirements
Do not spin specimen.
Collect: Dark Blue / Lav Strip
Auto Lab Accepts:
Unacceptable Conditions
Specimens collected in tubes other than royal blue (K2EDTA) or royal blue (NaHep).
Specimens transported in containers other than royal blue (K2EDTA) or royal blue (NaHep) tube or trace element-free transport tube. Clotted specimens.
Specimen Preparation
Transport 3 or 6 mL whole blood in the original collection tube. (Min: 0.5 mL)
Ordering Recommendations
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.
Potentially toxic ranges for blood arsenic: Greater than or equal to 600 ug/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.
Elevated results may be due to skin- or collection-related contamination, including the use of tubes that are not certified to be trace element free. If an elevated result is suspected to be due to contamination, confirmation with a second specimen collected in a certified trace element-free tube is recommended.
