Abstract:
1. A method of determining a subject's 24-hour urinary excretion of an analyte from a single sample of the subject's urine, comprising: measuring the analyte concentration in the single urine sample; measuring creatinine concentration in the single urine sample; using the subject's age, gender, race, weight, muscle mass, lean body mass, muscle mass, adiposity, physical activity, or a combination thereof, to select a normalized 24-hour creatinine excretion value from an array of normalized 24-hour creatinine excretion values, wherein each normalized 24-hour creatinine excretion value is an estimated mean of observed 24-hour urine creatinine concentrations for a population of persons of similar age, gender, race, weight, muscle mass, lean body mass, muscle mass, adiposity, and/or physical activity; and using the normalized 24-hour creatinine excretion value, the measured analyte concentration, and the measured creatinine concentration to determine the 24-hour urinary excretion of analyte for the subject.
