The invention relates to a method for detecting a dengue infection in a patient blood sample, comprising the steps: a) Performing an analysis of prespecified parameters of blood platelets and prespecified types of blood cells in the sample and determining parameter values for the prespecified parameters of the platelets and the prespecified types of cells; b) Obtaining sample parameters from the values determined in step a); and c) Evaluating the sample parameters in relation to a prespecified criterion, wherein, if the criterion is fulfilled, a dengue infection is present.

Methods of monitoring Klotho activity are provided.

A device for analyzing cell morphology and a method for identifying cells are provided. A digital camera photographs a cell image of a blood sample under a low-magnification objective lens. A processor identifies and positions suspected cells of preset type in the cell image to obtain an identification result. Based on the identification result and a target number, the processor determines a number of suspected cells of preset type to be identified and positioned under the low-magnification objective lens. The digital camera further photographs, under a high-magnification objective lens, the suspected cells of preset type identified and positioned, and then the processor identifies whether the suspected cells of preset type photographed are cells of preset type, to count the number of cells of preset type photographed under the high-magnification objective lens and obtain a statistical value. If the statistical value≥the target number, photographing is stopped.

Provided are cell image analysis devices and sample analysis methods. A sample smear of a test sample is imaged by an imaging device in an assigned analysis mode to obtain first cell images of the test sample, which are identified and analyzed by a control device. If it is identified that there is preset abnormality in the sample smear, an analysis mode different from the assigned analysis mode and corresponding to the present abnormality is determined as an additional analysis mode, and the imaging device is controlled to image the sample smear in the additional analysis mode. The additional analysis mode matches with the preset abnormality, so that the imaging device is allowed to obtain cell images in the additional analysis mode, to identify and analyze the cell images matching the preset abnormality, thereby increasing processing efficiency and accuracy of processing result.

The present invention provides a method of identifying and mitigating a risk of deathloss of an animal, comprising receiving, at a processor from a hematology analyzer, information obtained from a sample from said animal, wherein said information comprises a leukocyte absolute count and a leukocyte differential from said sample, said sample comprising leukocytes, analyzing, by said processor, said leukocyte absolute count and said leukocyte differential to determine a survivability index for said animal, and managing the animal based on the survivability index.

A sample analysis system, method and a cell image analysis device. The sample analysis system includes a blood cell analyzer, a smear preparation apparatus, a cell image analysis apparatus, and a controller. The controller obtains a test result of at least one sample from the blood cell analyzer. When one sample needs to be analyzed by the cell image analysis device, the controller can further control an imaging condition used by the cell image analysis device according to a value of at least one type of cells in the test result of the sample, such that the cell image analysis device can automatically selects an imaging condition matching the test result for imaging according to different test results of the sample. Therefore, a matching imaging condition is used to specifically capture and analyze cell images of a smear of the sample, thereby improving processing efficiency and accuracy.

A blood cell analysis method and a blood cell analyzer are provided. In the method and analyzer, characteristic information of white blood cell fragments is obtained based on side scattered light information and fluorescence information, characteristic information of platelets is obtained based on forward scattered light information and fluorescence information and then a count value for the platelets is acquired based on the characteristic information of the platelets and the characteristic information of the white blood cell fragments. The present invention can avoid the influence of the white blood cell fragments on the platelet counting, thereby ensuring the accuracy of the platelet counting without increasing costs.

A system consists of a detector and a detection card (9); the detector comprises a separation-detection turntable (4), a drive motor (3), a detection unit (5), a control and analysis unit (1), and a display unit (2); more than one detection card positions are arranged on the separation-detection turntable (4), and the separation-detection turntable (4) is driven by the drive motor (3) to rotate, so as to mix, separate and detect samples in the detection card; and the detection cards (9) are loaded on the detection card positions on the turntable, the detection card (9) is internally divided into more than two inner cavity pools, the divided inner cavity pools are respectively connected by narrow channels with a cross-sectional area less than 60% of a maximum cross-sectional area of each inner cavity pool, and all the inner cavity pools are unidirectionally connected in series.

The invention relates to a formulation for counting and morphological-based inference of erythrocytes and platelets to for use in clinical analyses, in particular hemograms, with the purpose of counting both erythrocytes and platelets in a liquid medium, and performing qualitative inferences of erythrocyte and platelet morphology, through image processing in Point-of-Care devices or through an optical microscope. This formulation preserves the natural morphological characteristics of erythrocytes and platelets, and uses methylparaben, propylparaben, sodium chloride, sodium bicarbonate, bovine serum albumin (BSA), sodium citrate, potassium citrate, K.sub.2EDTA and deionized water, which is advantageous in terms of operational simplicity and low cost.
