Sample analyzer and sample analyzing method

Abstract

The invention relates to a specimen analyzer, which can analyze the mixed specimen with specimen and agent. It comprises: a container, a specimen supplier, the first specimen supplier, the second specimen supplier, the first detecting part, the first mixture specimen supplier, the second detecting part, and the second mixture specimen supplier. Wherein, the container is used to contain the mixture specimen and the specimen; the specimen supplier supplies the specimen to said container; the first specimen supplier supplies the first specimen to the container; the second specimen supplier supplies the second specimen to the container; the first detecting part detects the first mixture specimen of specimen and the first specimen; the first mixture specimen supplier supplies the first mixture specimen from the container to the first detecting pat; the second detecting part detects the second mixture specimen of first specimen and second specimen; the second mixture specimen supplier supplies the second mixture specimen from the container to the second detecting part; the first mixture specimen supplier keeps some first mixture specimen in the container and supplies some to the first detecting part; and the second specimen supplier supplies some second specimen to the container that contains left first mixture specimen to prepare the second mixture specimen.

Description

technical field [0001] The present invention relates to a sample analysis device, a sample analysis method, and a blood analysis device. Background technique [0002] Red blood cells, platelets, and white blood cells are suspended in the plasma of peripheral blood. Multiple samples are examined because much clinical information can be provided based on the blood tests that examine these cells. [0003] As basic items in a blood test, the number of red blood cells, the number of platelets, the number of white blood cells, and the concentration of hemoglobin in blood are measured, and these measurement results are calculated to obtain hematocrit and the like. This test is generally called a CBC, and a hemacytometer is often used. [0004] A hemocytometer divides the blood into aliquots. For example, the first aliquot is diluted with diluent for determination of red blood cell count and platelet count. A second aliquot was used to determine the white blood cell count by lys...

Problems solved by technology

In addition, compared with the measurement of white blood cell count, leukocyte classification generally has a low inspection frequency. Therefore, in the existing cell counting device that requires special reagents for leukocyte classification, the reagents for leukocyte classification may reach the expiration date and cause waste.
