Abstract
A process is provided for analyzing a skin in any of a number of biochemical or immunological tests for an analyte which involves applying to a skin surface on a patient a reagent which selectively binds to the analyte to form an analyte-reagent complex; subjecting the skin surface on the patient to a treatment which develops a color correlating to an amount of analyte in the specimen; measuring a hue angle of the color developed on the skin surface of the patient by measuring a reflectance over a range of visible light spectrum at a plurality of intervals in wavelength of the visible light spectrum to obtain a measurement; and correlating the measurement of the hue angle to determine a concentration of the analyte.
Claims7
A process of analyzing a skin for an analyte comprising the steps of:
- applying to a skin surface on a patient a reagent which selectively binds to the analyte to form an analyte-reagent complex;
- subjecting the skin surface on the patient to a treatment which develops a color on the skin surface of the patient correlating to an amount of the analyte;
- measuring a hue angle of the color developed on the patient by measuring a reflectance over a range of a visible light spectrum at a plurality of intervals in wavelength of the visible light spectrum to obtain a measurement;
- and
- correlating the measurement of the hue angle to determine a concentration of the analyte.
