Reference Range
Arsenic, Blood <23 mcg/L
Whole Blood Arsenic level >100 mcg/L is indicative of acute/chronic exposure. Urine is usually the best specimen for the analysis of arsenic in body fluids. Blood levels tend to be low even when urine concentrations are high.

Lead, Blood  
0-6 Years <5 mcg/dL
>6 Years <5 mcg/dL
Blood lead levels in the range of 5-9 mcg/dL have been associated with adverse health effects in children aged 6 years and younger. Patient management varies by age and CDC Blood Lead Level range. Refer to the CDC website regarding Lead Publications/Case Management for recommended interventions.

Mercury, Blood ≤10 mcg/L
