Sample analyzer and specific protein detection method

Abstract

The invention provides a sample analyzer and a specific protein detection method. The sample analyzer comprises a sampling device, a hemolysis reagent supply device, a latex bin, an information reading device, a control device, a reaction tank and a detection device. The sampling device sucks a blood sample and dispenses the blood sample. The hemolysis reagent supply device is used for supplying a hemolysis reagent required by the test of a detection item. A reagent bottle is placed in the latex bin, a label carrying identification information is arranged on the reagent bottle, and the identification information at least comprises the type of a reagent in the reagent bottle. The information reading device reads the label on the reagent bottle to obtain the identification information. The controller controls the sampling device to sample and separate the latex reagent in the reagent bottle according to the identification information. The reaction tank receives the to-be-tested blood sampleseparately injected by the sampling device, the latex reagent and the hemolysis reagent so as to form a mixed sample required by testing. The detection device is used for detecting the mixed sample to obtain the specific protein concentration of the blood sample. The sample analyzer provided by the invention can be used for accurately sucking the required latex reagent.

Description

technical field [0001] The present application relates to the technical field of medical devices, in particular to a sample analyzer and a specific protein detection method. Background technique [0002] Sample analyzers such as automatic specific protein analyzers are commonly used in clinical testing. The automatic specific protein analyzer can be used for the detection of C-reactive protein (C-Reaction Protein, CRP), serum amyloid A (Serumamyloid A, SAA), etc. Due to the specificity of specific proteins, different latexes are required to detect different proteins. For example, CRP latex is needed to detect CRP, and SAA latex is needed to detect SAA. When the automatic specific protein analyzer is in use, the latex is stored in the heat preservation chamber of the specific protein analyzer, and the sampling needle draws the reagent from the reagent bottle storing the latex reagent and adds it to the sample for subsequent reaction and measurement. The traditional multi-c...

Problems solved by technology

The traditional multi-channel automatic specific protein analyzer will be equipped with multiple latex storage chambers, and different types of latex can be placed separately, but only the corresponding latex can be placed in the specific position, and it cannot be mixed. For example, position A can only hold CRP latex, and position B can only be placed. Only SAA latex can be placed, misplaced latex will cause latex suction error
