Lead in goat blood might not be on the top of your shopping list, but for U.S. medical personnel who each year perform more than 2 million human blood measurements, Standard Reference Material (SRM) 955c from the National Institute of Standards and Technology (NIST) can’t be beat.SRM 955c is an improved version of SRM 955b, a material clinicians already relied on heavily to provide quality assurance for lead blood measurements. Significant changes in material composition, lead levels and expanded uncertainties of the certified lead concentrations make SRM 955c an even more effective tool for use in addressing lead poisoning, a condition particularly harmful to the developing nervous systems of fetuses and young children, causing learning disabilities and behavior problems and, at high levels, seizures, coma and death.
