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: a cleaning solution is injected into a reactor located at a first station; magnetic particle conjugates in a reactor located at a second station are sucked on the reactor, and liquid waste in the reactor is sucked by a liquid suction part; a bearing assembly drives the reactors to reciprocate between the first station and the second station, cleaning solution injection and liquid waste suction treatment are alternately performed on the reactors, and the liquid waste is sucked by the same liquid suction part in the same reactor; and the reactor subjected to the cleaning solution injection and liquid waste suction treatment for set rounds is moved out of the cleaning position of the bearing assembly, the reactor subjected to the cleaning solution injection and liquid waste suction treatment not reaching the set rounds moves continuously with the bearing assembly, anew reactor which is not subjected to the cleaning solution injection and liquid waste suction treatment is moved to the cleaning position of the bearing assembly. The sample analysis method comprisesthe steps of the cleaning method. Therefore, the cleaning effect and analysis performance can be improved.

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.
