0099045: Arsenic, Blood

Test 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
