An apparatus for analyzing blood samples by detecting particle agglutination patterns formed on inclined bottom surfaces of reaction vessels formed in a microplate includes a diluted sample preparing section for delivering given amounts of blood cells and serum contained in a sample tube into diluting vessels mounted on a sample plate secured on a rotating endless belt and for discharging predetermined amount of a diluent into the diluting vessels to form diluted blood cell and serum samples, a diluted sample delivering section for delivering given amounts of the diluted blood cell and serum samples contained in the diluting vessels into an array of reaction vessels of the microplate in a selective manner according to test-items to be analyzed and a reagent delivering section for discharging given reagents into the reaction vessels. The microplate having the diluted blood cell and serum samples delivered therein is fed in a substantially stationary manner along a reaction line arranged in a vertical plane and in this reaction line the particle patterns formed on the reaction vessel bottoms are photoelectrically detected.

Analyzing apparatus and method for immunological agglutination reactions

A method of measuring an amount of total protein TP.sub.i of a test sample from an electrophoretic image of the test sample including a step of forming an electrophoretic image of a standard sample having a known amount of total protein TP.sub.1, a step of integrating absorbance values of the electrophoretic image of the standard sample to derive an integrated value of concentration D.sub.1 of the electrophoretic image, a step of integrating absorption values of the electrophoretic image of the test sample to derive an integration value of concentration D.sub.i of the electrophoretic image of the test sample, and a step of deriving the amount of total protein TP.sub.i of the test sample in accordance with an equation of ##EQU1## .

Method of measuring total protein of sample with the aid of

In a method of printing on a test report a pattern of fraction images of various kinds of proteins contained in a serum sample, an electrophoretic signal obtained by photoelectrically scanning a substrate bearing electrophoretic images is sampled to derive a number of digital samples, a reference digital sample having a maximum amplitude and denoting a peak point of albumin component is detected, a predetermined number of digital samples are extracted on the basis of the reference digital sample having the maximum amplitude, an electrophoretic image pattern is printed on a test report by using the extracted digital samples such that the reference digital sample is recorded at a predetermined point on the test report.
