Abstract
A method and apparatus for use in quantifying, in a whole blood sample in which the red cells are lysed, a component which will react with a reagent to form an antigen-antibody complex, the method comprising mixing the sample with the reagent to obtain the complex, exposing the sample to a source of radiation and measuring the intensity of radiation scattered through a given angle by the complex, and the apparatus including a container for receiving the sample which has been treated with the reagent to the component, the container being transparent to radiation having a wavelength falling within a given band width, typically 460-530 nm. A source of radiation within this band width is provided together with a device for detecting the intensity of radiation scattered through a given angle by the sample.
