ABSTRACT:
A method and apparatus is provided for analyzing the leucocytes in a biological fluid. The biological fluid is passed through a filter material having a critical wetting surface tension greater than 53 dynes/cm so that the leucocytes are held in the filter by adsorption. The filter material is subsequently treated with luminogenic material so that the treated filter may be analyzed by luminescence detection.
