Medical Providers

New Hampshire is now a ‘Universal’ pediatric blood lead level testing state that requires all children to have a blood lead level test at age one and a second test, at age 2.

Contact a Public Health Nurse

Public Health Nurses, working within New Hampshire Division of Public Health Services, Healthy Homes and Lead Poisoning Prevention Program, are available to answer health care provider questions on childhood lead exposure, blood lead level testing, and clinical management of children with elevated blood lead levels.

Nurse Case Management Services

The Division of Public Health Services provides nurse case management services at no cost to the families of all children with elevated venous blood lead levels at or above the State’s public health action level of 5 micrograms per deciliter (μg/dL). Nurse case management services begin with a nurse home visit to each child’s home and continue until child’s blood lead level has dropped below 5 μg/dL or until child is over 72 months of age.

NH Blood Lead 'Action Level' Triggering Public Health Intervention

New Hampshire's ‘action level’ under RSA 130-A Lead Paint Poisoning Prevention and Control is a venous blood lead of 5 micrograms per deciliter (μg/dL) for a child 72 months and younger.  When a child has a blood lead level of 5µg/dL or higher, this triggers nurse case management and an environmental investigation. New Hampshire's 'action level' is set by state law and is different from the blood lead reference value established by the Centers for Disease Control and Prevention (CDC) and lowered in October 2021 to 3.5 µg/dL.  

CDC’s Blood Lead Reference Value

CDC’s blood lead reference value of 3.5 µg/dL is a screening tool to identify children who have higher levels of lead in their blood compared with most children. The reference value is not health-based and is not a regulatory standard. States independently determine action thresholds based on state laws, regulations, and resource availability. Learn more about CDC’s Blood Lead Reference Value.

Distribution of Lead and Children Fact Sheet to Parents

New Hampshire state law requires that any health care provider conducting capillary blood lead level testing with point-of-care in-office analyzers, provide the Lead and Children factsheet to any parent or guardian of a child whose test indicates any presence of lead. The Lead and Children fact sheet is available as a PDF and in four other languages that can be found on our Publication and Resource page. To receive printed copied of the factsheet at no cost, contact:

Adults and Lead

Most adults with lead poisoning do not look or feel sick. Symptoms of lead poisoning include headaches, stomach cramps, constipation, muscle/joint pain, trouble sleeping, fatigue, irritability, and loss of sex drive. Lead exposure can cause high blood pressure and brain, kidney and reproductive health issues in adults. The Adult Medical Management ‘Quick Guide’ is available as a resource for Healthcare Providers that outlines what occupations are at risk for lead exposure and how to manage the follow up testing of adults that test positive for lead. The Lead and Adults fact sheet is available as an educational resource for adult patients that have tested positive for lead.
