The Lead Risk Questionnaire is a brief, structured screening tool — typically a five-item checklist derived from CDC guidance — that helps pediatric, family medicine, and public health teams identify children whose environment, household, or caregivers place them at elevated risk for lead exposure. A positive or "don't know" answer to any item indicates the need for a confirmatory capillary or venous blood lead test. Zentake's HIPAA-compliant digital platform lets clinics administer the questionnaire at check-in, auto-flag positive responses, and route results directly to the EHR for follow-up.
The most widely used version of the questionnaire is built on the CDC's 1991 five-question screening framework. The exact wording varies by state and health department, but the standard domains are:
1. Older or recently renovated housing. Does the child live in or regularly visit a house, child care facility, or relative's home built before 1960 (or 1978, depending on jurisdiction) with peeling or chipping paint, or that has had recent or ongoing renovation or remodeling within the last six months?
2. Household or playmate with elevated lead. Does the child have a sibling, housemate, or frequent playmate who is being followed or treated for lead poisoning (elevated blood lead level)?
3. Adult occupational or hobby exposure. Does the child live with or regularly spend time with an adult whose job or hobby exposes them to lead — for example, painting, plumbing, soldering, construction, battery recycling, auto repair, ceramics, stained glass, or firearms/ammunition?
4. Proximity to lead-producing industry. Does the child live near an active lead smelter, battery-recycling plant, or other industry that may release lead into the environment?
5. Additional jurisdictional risk factors. Many state and local health departments add items covering enrollment in Medicaid or WIC, recent immigration or international adoption, refugee status, use of imported foods, spices, cosmetics or traditional remedies, exposure to private well water, or living in a designated high-risk ZIP code.
A positive ("yes") or "don't know" answer to any item triggers a recommendation for a blood lead test. Many practices pair the questionnaire with universal blood lead screening at 12 and 24 months for Medicaid-enrolled children, and any child between 24 and 72 months without a documented prior test.
| Result | Interpretation | Recommended Next Step |
|---|---|---|
| All five answers "No" | Lower risk based on this screen | Routine re-screening at next well-child visit; follow state and Medicaid testing requirements |
| Any "Yes" or "Don't know" | Elevated risk | Order capillary or venous blood lead test |
| Medicaid enrollment, regardless of answers | Mandatory testing population | Blood lead test required at 12 and 24 months and any child 24–72 months without a documented prior test |
CDC uses a blood lead reference value (BLRV) of 3.5 µg/dL — children with confirmed blood lead at or above this level require follow-up, environmental investigation, and case management per CDC guidance.
| Capability | Paper | Zentake Digital |
|---|---|---|
| Risk flagging | Manual review after the visit | Real-time auto-flagging of any "yes" or "don't know" response |
| Scoring accuracy | Depends on staff review | Logic applied identically every time |
| Pre-visit completion | Not practical | SMS/email delivery before well-child visits |
| EHR integration | Manual scan or data entry | Direct routing to chart and lab order workflow |
| HIPAA documentation | Paper chart with chain-of-custody risk | Encrypted, audit-logged, role-based access |
| Public health reporting | Manual extraction | Structured data ready for state lead surveillance reporting |
All children from approximately six months through six years of age should be screened at each well-child visit, with focused attention at 12 and 24 months. The CDC and AAP recommend universal blood lead testing for all Medicaid-enrolled children at 12 and 24 months, and any Medicaid child between 24 and 72 months without a documented prior test, regardless of questionnaire responses.
CDC currently uses a blood lead reference value of 3.5 µg/dL. Children with confirmed blood lead levels at or above this value require follow-up testing, environmental investigation, nutritional counseling, and connection to case-management services per CDC clinical guidance. Specific follow-up timelines depend on the confirmed level.
No. The questionnaire is a risk-stratification tool — it identifies children who need a blood lead test, but a blood test is the only way to confirm exposure. Many jurisdictions also require universal testing for Medicaid-enrolled children and for children living in designated high-risk ZIP codes regardless of questionnaire answers.
Most caregivers complete the five-item version in two to three minutes. Expanded versions with state-specific items typically take five to ten minutes. Zentake's digital delivery removes paper handling and scoring time, so the only time cost is the parent or guardian's response.
Zentake stores responses as structured data with timestamps and patient identifiers in a HIPAA-compliant audit-logged record. Practices can export results in formats that align with state lead surveillance program requirements, and integration with the EHR allows lab results to be matched to the originating screening event.
The questionnaire screens for risk factors that suggest exposure may have occurred; a blood lead test measures the actual amount of lead in a child's blood. Risk-based screening helps target testing where it has the highest yield, but it does not detect every exposed child — which is why universal testing is required for high-risk populations.
