Problems solved by technology

[0004] However, in the conventional measurement method of serum information, since the reagent of the analysis item of the colorimetric analysis is used in the measurement, there is a disadvantage that the cost of the reagent increases.
In addition, due to the measurement of serum information, the processing capacity of the colorimetric analysis unit is reduced

Abstract

The present invention provides an automatic analyzer making it possible to reduce the cost for serum information measurement and prevent a decrease in processing capacity. An automatic analyzer comprises a colorimetric analysis section provided with a reaction vessel to mix a sample with a reagent and a measurement section to measure the color change of the mixture in the reaction vessel; and an electrolyte measurement section to measure the concentrations of electrolytes in a sample, wherein the sample included in the reaction vessel is diluted to be measured in the measurement section of the colorimetric analysis section, and at least one of the degrees of hemolysis, lipemia and icterus in a sample is measured in the electrolyte measurement section.

Description

technical field [0001] The invention relates to an electrolyte measuring device, in particular to a measuring method of an automatic analyzing device capable of performing colorimetric analysis and electrolyte analysis. Background technique [0002] The electrolyte measuring device is a device for measuring the concentration of a specific electrolyte component contained in a human body electrolyte solution, and uses an ion-selective electrode to measure the concentration of the electrolyte component. The method of determination is: directly supply the sample to the ion-selective electrode or use a diluent to supply the diluted solution of the sample to the ion-selective electrode to measure the potential level, and then (or before the above-mentioned measurement) use the known ion concentration The standard solution is supplied to the ion selective electrode to measure the potential level, and then the concentration of the sample is calculated according to the two potential ...
