Arsenic blood test is useful to detect acute or very recent arsenic exposure. Organic forms of Arsenic are normally present in certain food types. Inorganic Arsenic is carcinogenic to humans. This assay helps in the diagnosis of Arsenic intoxication. Since blood concentrations of Arsenic are elevated only for a short time after exposure, hence urine Arsenic is the preferred method of screening for Arsenic exposure.
Measurement of urine arsenic is the preferred method of screening for arsenic exposure.
Reference values apply to all ages – 0-12 ng/mL. Abnormal blood arsenic concentrations (>12 ng/mL) indicate significant exposure.
