ABSTRACT:
A method and device of quantitatively assaying an immunologically reactive substance of clinical interest, wherein the method includes the steps of grafting an immunologically active substance onto natural or synthetic microparticles, agglutinating the microparticles in a liquid medium in the presence of an immunologically reactive substance of clinical interest, and optically measuring the agglutinated substances to determine the assay of the immunological reactive substance of clinical interest. The device employed for carrying out the above method includes a first series of tubes which contain at least one freeze-dried calibration range of the substance to be assayed, a second series of tubes which contain an immunological active substance acting as the assaying agent, and a third series of small tubes containing a freeze-dried specimen of the dilution solution of the calibration range.
