A device as shown in Figure 4, for detecting the presence of at least one analyte in a biological sample comprising: (a) A source generating a light beam (170) having one or more predetermined characteristics as to the wavelength of the light beam, the light beam being incident on the biological samples; (b) A light detector receiving an altered light beam from the biological sample, the altered light beam having one or more characteristics as to the wavelength different from one or more predetermined characteristics of the incident light beam, the difference between the characteristics of the wavelength of the incident light beam and the altered light beam being caused by the presence of the biological sample; (c) A processor utilising the difference between the characteristics of the incident light beam (171) and the altered light beam (173) to detect the presence of at least one analyte in the biological sample; and (d) The source, light detector and processor being combined in a hand-held, portable arrangement for providing point-of-care detection of the presence of at least one analyte in the biological sample. A test strip (20) as described in Figure 1a and 1b, comprises an entire analytical matrix (25) having two zones; a first zone (30) serving the function of a "blank" and a second zone (32) being the reactant matrix zone. Zone (32) contains a first antibody in a porous non-reactive carrier matrix (46). The combination of both devices generally relates for detection and quantification of analytes in biological samples.
