A method, system, kit and uses for quantifying and normalizing at least one product of ethanol metabolism are provided. A method is provided for quantifying and normalizing at least one product of ethanol metabolism in a sample comprising creatinine. The method comprises adding a predetermined amount of at least one internal standard to the sample; adding deuterated creatinine to the sample; detecting and measuring at least one product of ethanol metabolism, the predetermined amount of at least one internal standard in the sample, the deuterated creatinine, and the creatinine. The method also comprises quantifying the amount of at least one product of ethanol metabolism in the sample using the measurement of the at least one internal standard; quantifying the amount of creatinine in the sample using the measurement of the deuterated creatinine; and normalizing the quantity of the at least one product of metabolism using the measurement of the creatinine.
