Detection of iron and zinc in human skin using non-invasive Raman spectrophotometer - A validation study among children under five years of age living in sub-Saharan Africa
This validation study in rural Burkina Faso and Kenya found that while the non-invasive Cell-/SO-Check Raman spectrophotometer is unsuitable for clinical diagnosis of iron and zinc deficiencies in children under five due to poor agreement with standard biomarkers, it may still be useful for ranking zinc status in population-based studies.
