Blood lead levels
Blood lead levels measure the amount of lead in a person's bloodstream, typically expressed in micrograms per deciliter (µg/dL). Lead is a toxic metal that can enter the body through contaminated water, soil, or dust, and exposure can cause serious health issues, especially in children, affecting development and cognitive functions. The Centers for Disease Control and Prevention (CDC) considers a blood lead level of 5 µg/dL or higher as a concern. Reducing lead exposure is crucial for health, particularly in homes, workplaces, and communities with known lead sources. Regular testing can help monitor and manage risks.

Blood lead levels refer to the concentration of lead found in a person’s bloodstream. Lead is a toxic metal that can harm various body systems, particularly in young children, where it can affect brain development, learning, and behavior. Elevated blood lead levels usually result from exposure to lead-based paints, contaminated soil, or certain plumbing. Health professionals measure these levels through blood tests, and values are expressed in micrograms per deciliter (µg/dL). The Centers for Disease Control and Prevention (CDC) considers a blood lead level of 5 µg/dL or higher as a cause for concern, necessitating further evaluation.
