Interpretive Data

Reference intervals are based on the CDC's Blood Lead Reference Value (BLRV). Thresholds and time intervals for retesting, medical evaluation, and response vary by state and regulatory body. Contact your State Department of Health and/or applicable regulatory agency for specific guidance on medical management recommendations.

Capillary collections are prone to contamination from skin and from use of nontrace element-free collection tubes. Results above the reference interval should be confirmed with a venous specimen collected in a certified trace element-free tube.

Methodology: Inductively Coupled Plasma-Mass Spectrometry (ICP-MS).
