Raman Chemometric Urinalysis (RametrixTM) was used to discern differences in Raman spectra from (i) 362 urine specimens from patients receiving peritoneal dialysis (PD) therapy for end-stage kidney disease (ESKD). (ii) 395 spent dialysate specimens from those PD therapies. and (iii) 235 urine specimens from healthy human volunteers. RametrixTM analysis includes spectral processing (e. https://chefesquipmenters.shop/product-category/adapter-bars/
