Performing Lab
Arsenic, Whole Blood
Clinical Use
Order TestUse
Monitor recent or acute exposure to arsenic
Special Instructions
In some cases, additional time may be needed for confirmatory or reflex tests. Testing schedules can vary.
Limitations
Arsenic has a short half-life in blood, making it primarily useful for assessing recent or acute exposure. This limits its effectiveness for chronic exposure assessment. The blood test should not be used as the sole measure for arsenic exposure; urine testing might provide better insights in some cases.
