Abstract
Disclosed is a transport method to be performed in an analysis system configured to transport a specimen to an analyzer configured to analyze an analyte contained in the specimen, the transport method comprising: cooling and preserving, in a cooling-and-preserving part, a quality control specimen containing an analyte having a known concentration; and controlling transport of the quality control specimen between the cooling-and-preserving part and the analyzer on the basis of a status of the analyzer.
Claims19
A blood analysis system comprising:
- a plurality of blood cell analyzers configured to perform the blood sample measurement on a blood sample;
- a supply device including a storage configured to store a quality control sample in a controlled temperature environment, wherein the quality control sample contains a known red blood cell concentration, a known leukocyte concentration and a known platelet concentration, and wherein the supply device is configured to supply the blood sample to the plurality of blood cell analyzers and to retrieve the quality control sample from the storage;
- a transporter configured to transport the blood sample and the quality control sample between the supply device and the plurality of blood cell analyzers;
- and
- a controller configured to control the transporter,
- wherein the controller is programmed to perform a quality control operation according to a schedule by:
- (i) controlling the supply device to retrieve the quality control sample from the storage;
- (ii) controlling the transporter to transport the retrieved quality control sample from the supply device to the plurality of blood cell analyzers;
- and
- (iii) controlling the transporter and the supply device to return the quality control sample to the storage after the quality control sample is transported to the plurality of blood cell analyzers, wherein the controller is further programmed to receive information regarding a deficiency occurring during the quality control operation and to execute, in response to the deficiency, a recovery operation of returning the quality control sample to the storage, thereby preventing the quality control sample from being left outside the storage without being returned due to the deficiency,
- wherein the deficiency is at least one of:
- (a) an insufficiency of a reagent to be used in at least one of the plurality of blood cell analyzers;
- (b) an error in reading of identification information provided on the quality control sample;
- (c) a measurement value abnormality of the quality control sample;
- (d) an error in a pressure of a pump for suctioning samples or reagents of at least one of the plurality of blood cell analyzers;
- (e) an error in a temperature of a reaction chamber of at least one of the plurality of blood cell analyzers;
- and
- (f) an error in an operation of a mechanism in at least one of the plurality of blood cell analyzers.
