Abstract
A total reflection cell has a total reflection prism on at least one surface thereof. A mixed solution containing a gold colloid labelled antibody which is adsorbed on a gold colloid is stored in the total reflection cell, and a sample solution containing an antigen causing antigen-antibody reaction with the antibody is added thereto for forming a gold colloid labelled immune complex. A measuring beam is introduced into the total reflection prism from an incident optical system at an angle θ of incidence causing total reflection and an outgoing beam from the total reflection prism is received by a measuring optical system, thereby measuring absorption by the gold colloid labelled immune complex and carrying out qualification and determination of the antigen.
