Claim 18:
19. 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;
(d) characterizing a urine sample as a natural urine sample based on the UCS; and
(e) performing genetic analysis of genetic material present in the urine sample.
