IPC: G01N33/58
Filed: 1992-10-30
Abstract: PURPOSE: To obtain an immunological determination method wherein a test result is not affected by 'exudation effect'. CONSTITUTION: In a non-uniform immunological test using the first bonding partner of the bonding pair fixed on a solid phase, a sample soln. containing an analyte is incubated along with a first complex consisting of the second bonding partner (a) of the bonding pair and a first substance (b) capable of being specifically and immunologically bonded to the analyte in the presence of the solid phase and, thereafter, phase separation is performed to substitute a liquid phase with a separate soln. containing a second label substance.  Incubation is again performed and phase separation is performed and a finally separated label is measured as the index of the amt. of the analyte and, before incubation, a second complex consisting of the macromolecule (a) incapable of being bonded to the analyte and the second bonding partner (b) of the bonding pair is further added to a liquid phase in an amt. excessive to the first complex.

The circuit 4 can perform the OR, the AND, the addition, the subtraction, the multiplication, etc., and outputs these arithmetic results as the arithmetic outputs. When the inputs 1-3 show L11, L21 and L23 respectively, the data to be computed show the digits, i.e., N=1, N=2 and N=3. Meanwhile the data to be computed are shown in the digits N=7, N=5 and N=3 with the inputs 2 and 3 equal to L22 and L31 respectively. These data are outputted from the ROM 1-3. Thus just a single reading operation suffices read of the ROM, therefore the processing time is shortened.
