Who to Test for Lead Poisoning
Healthcare providers should assess all children for risk of lead poisoning at 12 and 24 months of age. The Department of Health recommends performing a blood lead test on children with the following risk factors:
- Lives in or regularly visits any house built before 1950.*
- Lives in or regularly visits any house built before 1978 with recent or ongoing renovations or remodeling.
- From a low income family; income
- Known to have a sibling or frequent playmate with an elevated blood lead level.
- Is a recent immigrant, refugee, foreign adoptee, or child in foster care.
- Has a parent or principal caregiver who works professionally or recreationally with lead. (Examples: remodeling and demolition; painting; works in or visits gun ranges; mining; battery recycling; makes lead fishing weights or shotgun pellets; hobbies involving stained glass, pottery, soldering, or welding).
- Uses traditional, folk, or ethnic remedies or cosmetics. (Examples: Greta, Azarcon, Ghasard, Ba-baw-san, Sindoor and Kohl).
*Screening may not be indicated if the home has previously undergone lead abatement or tested negative for lead after remodeling.
**The Health Care Authority has applied for a waiver to perform targeted testing in children covered by Apple Health. The waiver request is currently pending.
Healthcare providers should consider testing additional children per clinical judgment, such as:
- Children whose parents have concerns or request testing (including older children that have risk of exposure).
- Children living within a kilometer of an airport or lead emitting industry, or on former orchard land.
- Children with pica behavior.
- Children with neurodevelopmental disabilities or conditions such as autism, ADHD, and learning delays.
Other consumer products found to have lead risk are informally imported foods and spices. Some candies imported from Mexico have been found to contain lead. Certain ingredients used in the candies, such as chili powder and tamarindo, are found to be the most common source of exposure. Lead has also been found in the ink of some imported candy wrappers as well as in nonregulated imported spices such as turmeric.
