Blood cell analyzer, body fluid analysis method and control system

Abstract

The present invention provides a blood cell analyzer, which includes: a measurement mode setting unit for setting a body fluid measurement mode; a measurement start instruction unit for accepting an instruction to start measurement; and an optical information acquisition unit for illuminating a sample. The optical information is obtained from the cells contained in the measurement sample; the analysis unit, after the above-mentioned body fluid measurement mode is set, when the above-mentioned measurement start instruction unit receives an instruction to start the measurement, based on the above-mentioned measurement test prepared from the body fluid sample and the leukocyte measurement reagent Using the optical information obtained from the sample, the cells contained in the measurement sample are classified into at least leukocytes and nucleated cells other than leukocytes, and the leukocytes and nucleated cells other than leukocytes are counted. The invention also provides a body fluid analysis method and a control system.

Description

Technical field: [0001] The present invention relates to a blood cell analyzer, a body fluid analysis method and a control system thereof capable of measuring not only blood but also other body fluids such as cerebrospinal fluid (spinal fluid), pleural fluid (pleural fluid) and ascites as a sample. Background technique: [0002] In the field of clinical examination, blood cell analyzers are commonly used to analyze blood collected from the body as the test sample, and use the analysis results as one of the references for diagnosis and treatment monitoring. [0003] At the same time, in the field of clinical examination, it is desired to be able to measure body fluids other than blood, such as cerebrospinal fluid, easily and easily. Usually there are few cells in the body fluid, but when there is a disease or there is a tumor or damage to the relevant organ, cells such as bleeding (blood cells) and abnormal cells and bacteria are found.
