The criterion standard is a whole blood lead level (BLL). Any BLL higher than 10 Âµg/dL is considered positive and consequential. Patients with BLLs between 10 and 20 Âµg/dL require removal from the exposure, repeated testing, and follow-up. A free erythrocyte protoporphyrin (FEP) level may be useful in demonstrating the degree of biological abnormalities that exist.
