Abstract: A method for detecting an analyte in a bodily fluid includes placing the detector in contact with at least one metabolite resulting from the metabolism or degradation of the analyte. The contact between the detector and the metabolite produces an optically detectable signal. The detection method includes the detection of the metabolite only in gas form, said metabolite in gas form coming from the evaporation of at least a part of said metabolite. The detection is also carried out without contact between the bodily fluid and the detector. A dressing for implementing the detection method is also described.

Abstract: In a urine component analysis device, a correlation storage section stores data indicating a correlation between a measured concentration in one urine and in total urine in one day for each of a first and second specific component in the urine excreted by a human. A data input section inputs data indicating a concentration of the first specific component and of the second specific component in one urine of a subject. A concentration of the first specific component and of the second specific component in total urine in one day are determined by performing conversion using the correlation stored in the correlation storage section based on the concentration of the first specific component and the second specific component in the one urine. A concentration ratio between the first specific component and the second specific component in total urine in one day is determined based on the results of conversion.
