Background: Lead has not any vital function in the human body, but is toxic even at low doses, leading to acute and chronic effects. Studies in Latin Americans children have showed that lead poisoning is a major health problem, because there are different forms of exposure. There are no established maximum permissible serum levels which can guarantee long-term security. Type of study: Cross-sectional, analytical, performed with a convenience sample. Methodology: CINVESTAV made the determination of lead in blood samples from bags stored in the blood bank of the General Hospital of Ecatepec, in the period from December 2012 to January 2013. Results was given according with the criteria of the norm NOM-047 -SSA1-2011. Results: 225 samples were analyzed, finding 163 donor samples at low levels (<5 µg/dL), 46 samples in the range of 5 to 10 µg/dL and 15 samples with values between 10 to 19 µg/dL. Recommendations: 1. It is essential to determine the values of lead donor blood before transfusing patients. 2. Include a screening of the donor blood lead levels. 3. It is essential to limit this risk factor that contributes to neurological damage in newborns, like the high lead serum levels.
