Agencies Warn of Faulty Blood Tests for Lead, Recommend Retesting
By Kelly Young
Some blood tests made by Magellan Diagnostics may falsely report low lead levels in children and adults, the FDA and CDC cautioned on Wednesday.
The FDA is warning against using Magellan Diagnostics LeadCare analyzers with venous blood samples. The alert doesn't apply to blood collected by finger- or heelstick.
Children currently younger than 6 years need to be retested if they had venous blood samples analyzed with any of the following Magellan products — LeadCare, LeadCare II (which is used in provider offices and clinics), LeadCare Plus, or LeadCare Ultra – and their results were 10 µg/dL or less. Pregnant and nursing women should also be retested.
The problem with falsely low readings began as far back as 2014, the FDA said.
