Blood Lead
BLOOD LEAD
Blood lead is a biomarker used for monitoring occupational and environmental lead exposure. The Occupational Safety and Health Administration (OSHA) has established the following blood lead screening guidelines and actions for workplace exposure: over 60 micrograms per deciliter (>60 mcg/dL): removal from workplace; >50 mcg/dL in three consecutive months: removal of individual from workplace; >40 mcg/dL: medical evaluation only: a goal of the ABLES program of the Centers for Disease Control and Prevention is a guideline of <25 mcg/dL. The Centers for Disease Control and Prevention (CDC) has established the following blood lead screening guidelines and actions for childhood environmental lead exposure: <9 mcg/dL: acceptable background lead exposure; 10 to 19 mcg/dL: more frequent rescreening and nutritional/educational interventions; 20 to 44 mcg/dL: consider pharmacologic therapy; 45 to 69 mcg/dL: pharmacologic therapy; >70 mcg/dL: medical emergency.
