Recommendations and Requirements for Blood Lead Testing in Missouri

The Center for Disease Control (CDC) and the Association of Pediatrics work together to provide recommendations for blood lead testing. The Centers for Medicare and Medicaid Services (CMS)/Missouri Department of Social Services, Division of Medical Services and Department of Health and Senior Services have state requirements for the blood lead testing of children.

Childhood Lead Testing Requirement Areas

The State of Missouri categorizes its testing areas into two designations:

A testing designation is given to a geographic area based on a formula developed by the Department of Health and Senior Services. An area’s designation may change based on the yearly information provided by that area. These testing requirement designations assist physician’s offices, local health departments, and others in determining whether children are required or recommended to be tested for lead. Regardless of the designation in which you live, it is recommended that all children be screened and/or tested for lead annually.

The Department publishes the testing requirement area maps annually, in April. The testing requirement maps for the State of Missouri can be viewed at:

Methods of Testing

The choice of a sample collection method (venous or capillary) should be determined by the physician. Capillary sampling can perform well as an initial testing tool. If the results of the capillary are 10 μg/dL or greater, the capillary results should be confirmed with a venous blood draw.
