1. A method of determining a patient profile of a peritoneal dialysis patient, the method comprising:
obtaining a volume of fluid associated with the peritoneal dialysis patient;
generating patient information via fluorescence analysis of the patient fluid; and
determining the patient profile based on evaluating the patient information with a profile library, wherein the profile library comprises peritoneal equilibration test (PET) information and the patient profile comprises a peritoneal transport status classification;
wherein fluorescence analysis includes:
capturing two-dimensional (2D) fluorescence measurements comprising systematically scanning an excitation wavelength of the patient fluid while a corresponding emission spectra of the patient fluid is captured; and
generating, based on the 2D fluorescence measurements, a 2D correlation map enabling identification of multiple fluorophores in the patient fluid.
