Embodiment Construction

[0105] specific implementation plan

[0106] The specific implementation of the sample testing system of the present invention will be described in detail below according to the accompanying drawings.

[0107] Hereinafter, in this embodiment, a hematology analyzer for counting red blood cells (RBC), white blood cells (WBC), platelets (PLT) and the like in blood as an example will be specifically described with reference to the drawings.

[0108] In addition, in this specification, when expressed as the number of white blood cells or WBC, it does not refer to the number of white blood cells obtained by counting white blood cells classified into subgroups as in the DIFF item, but the total number of white blood cells counted without dividing the white blood cells into subgroups. .

[0109] In this specification, the term "abnormal cells" refers to blood cells that appear more frequently in the peripheral blood of patients with diseases than in the peripheral blood of healthy pe...

Abstract

A blood analyzer comprising: a specimen preparation section for preparing a measurement specimen that is used to measure a white blood cell count among CBC measurement items; a measurement section for obtaining optical information from blood cells contained in the measurement specimen; and a controller carrying out operations comprising: classifying blood cells contained in the measurement specimen into at least white blood cells and blood cells suspected to be abnormal blood cells based on the optical information; obtaining distribution data of the white blood cells and distribution data of the blood cells suspected to be abnormal blood cells; counting the white blood cells based on the distribution data of the white blood cells; and determining presence or absence of the abnormal blood cells in the blood sample, based on the distribution data of the blood cells suspected to be abnormal blood cells. A blood analyzing method and a computer program product are also disclosed.

Description

technical field [0001] The invention relates to a blood analyzer capable of measuring blood samples to detect abnormal blood cells, a blood analysis method and a control system thereof. Background technique [0002] Historically, people have known a hematology analyzer for classifying and counting the formed components in blood into red blood cells, white blood cells, and platelets, etc., and the hematology analyzer can set measurement modes according to measurement items. Such as U.S. Patent Application Announcement 2008 / 187990 has announced a sample analyzer, the user can set a measurement mode from the following two measurement modes arbitrarily, one is to measure red blood cell count (RBC), white blood cell count (WBC) Complete blood count (CBC) consisting of platelet count (PLT), hemoglobin concentration (HGB), hematocrit (HCT), mean corpuscular volume (MCV), mean corpuscular hemoglobin content (MCH) and mean corpuscular hemoglobin concentration (MCHC) The CBC mode of ...
