Cleaning method and sample analysis method

Abstract

The invention relates to a cleaning method and a sample analysis method. The cleaning method comprises the following steps: injecting a cleaning solution into a reactor at a first station; injecting a magnetic particle conjugate in a reactor at a second station It is adsorbed on the reactor, and absorbs the waste liquid from the reactor through the liquid absorbing part; the bearing component drives the reactor to reciprocate between the first and second stations, so that the reactor can alternately inject cleaning liquid and absorb waste liquid treatment, and the same reactor absorbs waste liquid through the same liquid suction part; and the reactor that has reached the set round of injection of cleaning liquid and suction of waste liquid is removed from the cleaning position of the bearing assembly, and the set round is not reached. The reactor after injecting cleaning liquid and absorbing waste liquid for the first time continues to follow the movement of the carrying assembly, and moves the new reactor that has not been treated with injecting cleaning liquid and drawing waste liquid into the cleaning position of the carrying assembly. The sample analysis method includes the steps of the cleaning method. This improves cleaning and analytical performance.

Description

technical field [0001] The invention relates to the technical field of in vitro diagnosis, in particular to a cleaning method and a sample analysis method comprising the cleaning method. Background technique [0002] Fully automatic immunoassay is based on the immunological reaction of the combination of antigen and antibody, using enzyme labeling, lanthanide labeling or chemiluminescence to label the antigen and antibody, and through a series of cascade amplification reactions, the optical signal or electrical signal is combined with the analyte The antigen or antibody to be tested in the human sample is analyzed in relation to the concentration and the like. [0003] In the measurement and analysis, it involves the cleaning and separation of the analyte (Bound-free, hereinafter referred to as cleaning), that is, the magnetic force is used to capture the complex of the bound magnetic particles, antigen and labeled antibody (ie the analyte), and finally remove the unidentifi...

AI Technical Summary

Problems solved by technology

[0004] Generally, for traditional cleaning methods and sample analysis methods, either the contamination of the next reaction vessel will be formed during the process of pumping waste liquid, or the adsorption of the analyte will affect the cleaning effect and analytical performance.
