LAMP: A CDC Program to Ensure the Quality of Blood-Lead Laboratory Measurements.CONTEXT
 To investigate the ability of US laboratories, participating in the Centers for Disease Control and Prevention (CDC) LAMP program to accurately measure blood-lead levels (BLL) 0.70 to 47.5 μg/dL using evaluation criteria of ±2 μg/dL or 10%, whichever is greater.


 The CDC distributes bovine blood specimens to participating laboratories 4 times per year.  The CDC sent 15 pooled samples (3 samples shipped in 5 rounds) to US laboratories.  Laboratories reported their BLL analytical results to the CDC.  The CDC sent blood samples to approximately 50 US laboratories for lead analysis.


 Laboratories participating in the CDC's LAMP program can accurately measure blood lead using the current Clinical Laboratory Improvement Amendments of 1988 guidance of ±4 μg/dL or ±10%, with a success rate of 96%.  When challenged with samples that have target values between 3 and 5 μg/dL, nearly 100% of reported results fall within ±4 μg/dL, while 5% of the results fall outside of the acceptability criteria used by the CDC's LAMP program.
