Blood Tests Significantly Underestimated Lead Levels, FDA And CDC Warn 

May
23

Federal officials are warning that some blood tests may have “significantly” underestimated lead levels, and they are urging the retesting of some children, as well as pregnant and breast-feeding women. The Food and Drug Administration and the Centers for Disease Control and Prevention said the tests in question were made by Magellan Diagnostics, a Massachusetts-based testing company whose products are used in laboratories and doctors' offices throughout the country. The problem may go as far back as 2014, the agency said. The warning applies only to tests in which blood samples are taken from a vein, not the more common, less invasive tests in which fingers or heels are pricked for a blood sample. (McGinley, 5/17)
