    • Description:
      The Centers for Disease Control and Prevention (CDC) has been involved in preventing human exposure to lead and lead poisoning for a number of years. Over time, as an understanding of the adverse health effects of lead poisoning has grown, public health officials have recognized the need for accurate and precise blood lead measurements.

      CDC began the Blood-Lead Laboratory Reference System (BLLRS) in 1990 to help laboratories ensure consistent, high-quality blood-lead measurements. Because of the success of the program, CDC expanded BLLRS in 2006 to include more elements and gave it a new name: the Lead and Multi-Element Proficiency Program, or LAMP.

      LAMP is a voluntary program that focuses on assuring the quality of multi-element analyses in whole blood. At least 100 laboratories, including

      30 international labs, participate in LAMP. Each quarter, these laboratories are required to analyze

      a set of blood samples provided by CDC and return the analyses results to CDC. CDC provides detailed reports to participating laboratories about how well they performed these analyses. LAMP results are not used for accreditation or certification; however, the program does improve the precision and accuracy of blood lead, cadmium, and mercury measurements. In the future, other inorganic toxicants, such as arsenic, selenium, and uranium, will be added to the program.
