Fasting Required: No Specimen: Blood Results: 3-5 Business Days Description: Lead is a soft metal present in the environment. When it is inhaled or ingested, lead can cause damage to the brain, organs, and nervous system. Even at low levels, it can cause irreversible damage without causing symptoms. Methodology Inductively Coupled Plasma/Mass Spectrometry (ICP/MS) or Atomic Spectroscopy (AS) Reference Range(s) Birth-6 Years <5 mcg/dL >6 Years <10 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 Level Range. Refer to the CDC website regarding Lead Publications/Case Management for recommended interventions. Clinical Significance Blood lead is useful in detecting industrial, dietary and accidental exposure to lead and to monitor detoxification therapy.
