Arsenic, Blood : 0099045

Mnemonic: ARS B

Methodology: Inductively Coupled Plasma/Mass Spectrometry
Performed: Mon-Sat
Reported: 1-3 days
Specimen Required: Collect:  One 7 mL royal blue (K2EDTA) or (Na2EDTA).

Transport:  7 mL whole blood at 20-25°C. (Min: 1 mL)

Pediatric Collection/Transport:  0.5 mL whole blood at 20-25°C.

Unacceptable Conditions:  Heparin anticoagulant.

Stability:  If the specimen is drawn and stored in the appropriate container, the trace element values do not change with time.
Reference Interval:
0.0-13.0 µg/L
Interpretive Data: 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.
Note: Elevated results from noncertified trace element-free collection tubes may be due to contamination.  Elevated concentrations of trace elements in blood should be confirmed with a second specimen collected in a tube designed for trace element determinations, such as a royal blue (Na2EDTA) tube.
CPT Code(s): 82175
