Project TitleQuantification of Heavy Metals in Dried Blood Spots
Track Code2012-186
Short Description

A "field-friendly," non-invasive method for quantifying human exposure to heavy metals, especially in children. #healthcare #diagnostictool #medicaldevice #diagnosticsandmeasurement

Abstract

Northwestern researchers have developed a "field-friendly" and non-invasive approach to determining environmental exposure to heavy metals. Drops of whole blood are collected on pre-treated filter paper following a simple finger or heel stick. The invention includes a dried blood spot (DBS) collection device and kit for quantifying heavy metal blood concentrations.
