Blood Lead Surveillance Branch

As of January 1, 2023, the Texas Department of State Health Services (DSHS) has implemented a blood lead reference value (BLRV) of 3.5 micrograms per deciliter (µg/dL), as recommended by the Centers for Disease Control and Prevention (CDC). DSHS uses a BLRV of 3.5 µg/dL to identify children with blood lead levels that are higher than most children's levels. The Reference for Blood Lead Retesting and Medical Case Management, Pb-109 form provides guidance for blood lead levels ≥3.5 µg/dL and has been updated to reflect CDC guidance.

The Blood Lead Surveillance Group is made up of two programs:

1. The Texas Childhood Lead Poisoning Prevention Program
2. The Adult Blood Lead Epidemiology and Surveillance Program

The Texas Childhood Lead Poisoning Prevention Program (TXCLPPP) maintains a surveillance system of blood lead results on children younger than 15 years of age. Texas law requires reporting of blood lead tests, elevated and non-elevated, for children younger than 15 years of age. Physicians, laboratories, hospitals, clinics, and other healthcare facilities must report all blood lead tests to the Texas Child Lead Registry.

The Adult Blood Lead Epidemiology and Surveillance Program (ABLES) maintains a surveillance system of blood lead test results on individuals 15 years of age and older. Laboratories and physicians are required by the Texas Reportable Occupational Conditions Act to report all blood lead levels.
