Determination of creatinine level in patient blood samples by Fourier NIR spectr

In this paper, in vivo spectra from 23 patients' blood samples with various Creatinine (Cr) concentration levels ranging from 0.96 to 12.5 mg/dL were measured using Fourier transform near-infrared spectrometer (FT-NIRS) and spectrum quantitative analysis method. Since Cr undergoes passive filtration
