Lead Screening and Testing

The State of Delaware is working with schools and health care partners to ensure free and accessible lead screening is available to families. There are two types of tests for the presence of elevated blood lead levels: Finger Sticks/Capillary Test (known as a lead screening) and Venous Tests (known as a blood test).

DPH Mobile Unit

The Division of Public Health performs Blood Lead Screenings (Capillary Fingerstick), as well as the following health services, through its Community Health Services Mobile Unit:

While there is no safe level of lead in children’s blood, capillary screening results 3.5 µg/dL or higher are considered “elevated” and require further action.

Step 1. Confirmatory Test

Capillary screening results of 3.5 µg/dL or higher require a confirmatory venous (blood) test. Please contact your child’s primary care physician for this confirmatory blood testing for lead.

The CDC’s recommended schedule for obtaining a confirmatory blood test is as follows and becomes more urgent with higher screening results:

• 3.5 to 9.9 µg/dL – testing within 1 to 3 months
• 10 to 44 µg/dL – testing within 1 week to 1 month
• 45 to 59 µg/dL – testing within 48 hours
• 60 to 69 µg/dL – testing within 24 hours

If the test confirms an elevated blood lead level, follow-up testing to track changes to the blood lead level may be necessary.

Step 2. Identify and Remove the Source of Exposure

Lead can be found in numerous places in the home and in a child’s environment, including lead dust from peeling paint, contaminated soil, drinking water (pipes/solder), vintage dinnerware as recent as 2005, certain food items, imported spices, imported cookware, imported makeup, costume jewelry, toys, imported supplements, and more.

Delaware’s Childhood Lead Poisoning Prevention Program will mail a packet of information to assist parents in identifying the source of exposure, and families may receive a free home risk assessment if the confirmatory bloodtest is 7.0 µg/dL or higher.

Residents of certain ZIP codes in New Castle County may be eligible for home remediation. The “No Lead” program addresses and remediates lead hazards in homes within 5 ZIP codes: 19703, 19720, 19801,19802, 19805, and 19806. Households with children under the age of 6, with pregnant women, or those built before 1978 may be eligible. Learn More

Step 3. Importance of Diet

Feed children healthy, low-fat foods high in iron, calcium, and vitamin C, which helps prevent lead from being absorbed. Because lead is more easily absorbed on an empty stomach, more frequent small meals are recommended.

Step 4. Early Education

Early education exercises the brain, builds neural networks, and can help overcome the cognitive effects of lead poisoning. All Delaware children ages birth to three years with a confirmatory venous test of 5 µg/dL or higher are automatically eligible for early intervention services.
