ABSTRACT:
An apparatus is so constructed as to measure a specific substance in a test specimen by the degree of the aggregation of carrier particles in a reaction solution in which the test specimen is mixed with the carrier particles which carry a substance specifically binding to the specific substance. The apparatus includes a substrate having comb-shaped electrodes mounting the reaction solution and amplifier and alternating oscillator for displaying a variable voltage to the comb-shaped electrodes. The test specimen measuring apparatus having the structure accelerates the aggregation of the reaction solution by applying an alternating voltate to the comb-shaped electrodes in a state that the reaction solution is being mounted on the substrate, and detects the spatial spectrum of the comb-shaped electrodes on which the reaction solution is mounted, thus performing the qualitative or quantitative detection of the presence of the substance in the test specimen.
