A method for quantifying at least one metabolite in at least one biological sample comprising the steps of: (a) providing at least one biological sample obtained from a patient on a prescribed medication regimen, wherein the biological sample comprises at least one test metabolite; (b) providing one set of known normative data specific to a reference metabolite, wherein the set of data is collected from a population that is on a prescribed medication regimen; (c) contacting the biological sample with an analytical device; (d) detecting the presence of at least one test metabolite in the biological sample with the device, wherein the device is capable of measuring the concentration of the test metabolite in the at least one biological sample; (e) normalizing the biological sample to adjust for changes in the patient's hydration status by determining the metabolite/creatinine ratio of the patient; and (f) quantifying the concentration of at least one test metabolite in the biological sample by comparing a ratio between the concentration of the test metabolite from the patient to the set of known normative data specific to the reference metabolite concentration. view more
