Under the state notifiable conditions rule (WAC 246-101) all blood lead test results (regardless of the value) must be reported to the Washington State Department of Health (DOH) by the lab that analyzed the blood sample. Facilities using LeadCare point-of-care devices are the lab under this standing medical order.
DOH is responsible for collecting and uploading lead test results into the state database so that data is available to the local health jurisdictions.
Blood lead case investigations are within the jurisdiction of the county where the child resides. DOH is available to provide support to local public health staff in investigating cases where the blood lead level is at or above the reference value of 3.5 micrograms per deciliter.
