Raman spectra from 235 urine specimens from healthy individuals.
(A) Overlaid vector normalized spectra. (B) The average urine spectrum (black) with ranges of 1 (red) and 2 (blue) standard deviations.
Fig 2.
Principal component analysis (PCA) results for Raman spectra of 235 urine specimens from healthy individuals.
PCA results based on (A) year individual was born and (B) sex of individual. (C) Contributions of Raman shift leading to separations among principal components.
