Abstract: An improved optical detection unit for an assay device, such as a lateral flow device, for the quantitative determination of the concentration of an analyte in a liquid sample, and an assay device comprising the same. The detection unit comprises an organic light emitting diode (OLED) emitter that has an emission spectrum E within the wavelength range from λ1 to λ2, and an organic photodiode detector (OPD) that has a light detection spectrum S within the wavelength range from λ1 to λ2. The detection unit has a test region that comprises a light absorbing component that has an absorbance spectrum A within the wavelength range from λ1 to λ2. The test region is positioned adjacent to the emitter and the detector to form an optical pathway from the light emitting diode to the photodiode through at least a portion of the test region. Formula M defines a relationship between E, S and A, and M is less than about 0.4.
