Two-wavelength excitation spectroscopy for non-invasive detection of the iron deficiency indicator zinc protoporphyrin IX

Not Accessible

Your library or personal account may give you access

Abstract

Increased formation of fluorescent zinc protoporphyrin IX (ZnPP) inside erythrocytes indicates functional iron deficiency. Two-wavelength excitation spectroscopy detects ZnPP even through intact skin. Its suitability was successfully tested in women, surgical patients, infants and blood donors.
