Result Interpretation

Environmental exposure:    0.0 - 3.4 ug/dL 

Environmental exposure (WHO): <20 μg/dL

• Occupational exposure: BEI® (sampling time is not critical): 30 μg/dL;1 OSHA Lead Standard: 40 μg/dL

The Centers for Disease Control and Prevention recommends the following testing schedule for children with elevated BLLs (blood lead levels) on a screening test.2 See table.
