Claim:
1. A measurement apparatus comprising: a cooling device including two separated, different substances exhibiting an endothermic reaction when combined to decrease a temperature of the cooling device; a combining mechanism of the cooling device configured to combine the two different substances; a contacting mechanism configured to contact an assay surface of a subject's body with the cooling device and to decrease a temperature of the assay surface of a subject's body with the cooling device to a lower temperature, the contacting mechanism including: a temperature measurement device configured to measure a temperature of the assay surface of a subject's body during an increase of the temperature from the lower temperature; an infrared radiation detector configured to measure infrared radiation emitted from or absorbed by the assay surface of a subject's body during the temperature increase; and a data processor configured to determine a rate of temperature change of the assay surface and configured to determine a concentration of a substance in the subject's body using the measured temperature of the assay surface, the measured infrared radiation, and the rate of temperature change.
