Claim 17:
18. A method of identifying a condition of a subject, comprising:
obtaining Raman spectra from a urine sample from a subject using the system of claim 1;
comparing the Raman spectra of the urine sample to a selected model;
wherein the selected model is constructed from various Raman spectra of urine from individuals having and not having a specified condition; and
wherein the comparing of the Raman spectra of the urine sample to the selected model comprises identifying whether the urine sample is classified according to the selected model as being urine either from a subject who has or does not have the specified condition;
wherein the selected model is constructed from:
one or more multivariate analysis techniques applied to various Raman spectra of urine from individuals having and not having a specified condition;
wherein one or more of the multivariate analysis techniques involves identifying statistically significant spectral differences between the urine from the individuals having the specified condition and those not having the specified condition.
