| 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. |
