1. A method of characterizing a urine sample from a subject, the method comprising:
- (a) providing a urine sample from a subject;
(b) determining one or more of the light absorption, luminescence, phosphorescence, fluorescence, and chemiluminescence of the urine sample at two or more wavelengths of light;
(c) applying one or more eigenvectors derived from a principle component algorithm to a standardized dataset derived from the determined light absorption, luminescence, phosphorescence, fluorescence, and chemiluminescence of the urine sample to generate a Urine Characterization Index (UCI) comprising one or more values for corresponding principle component(s); and
(d) characterizing a urine sample as a natural urine sample, a lyophilized urine sample, a diluted natural urine sample, a synthetic urine sample, or a chemically-adulterated urine sample based on the UCI.

12. A method of characterizing a urine sample from a subject, the method comprising:
-
(a) providing a urine sample collected from a subject; (b) determining the absorbance at a first wavelength (A1) and the absorbance at a second wavelength (A2) of the urine sample, wherein the first wavelength is from about 230 nm to 250 nm, and the second wavelength is from about 260 nm to 340 nm; (c) applying an algorithm to the determined A1 and the determined A2 to generate a Urine Characterization Score (UCS), wherein the algorithm includes a ratio of the determined A1 to the determined A2; and (d) characterizing a urine sample as a natural urine sample, a chemically-adulterated urine sample, a lyophilized urine sample, a diluted natural urine sample, or a synthetic urine sample based on the UCS. - View Dependent Claims (13, 14, 15, 16, 17)
