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.

Measurement of an analyte on the skin using a hue angle

A process is provided for analyzing a specimen of biological material in any of a number of biochemical or immunological tests for an analyte which involves subjecting the specimen to treatment which develops a color correlating to the amount of analyte in the specimen. According to the invention at least one defined color characteristic selected from hue angle, chroma, saturation and lightness of the developed color is measured and the results of that measurement analyzed to determine the presence or concentration of the analyte in the specimen. Particular applications are to the detection of cancerous or pre-cancerous abnormalities from the analysis of lung mucus, throat mucus, cervical mucus or seminal fluid.
