The present disclosure provided a blood cell analyzer, a control device and a blood analysis method thereof. In the method, a first reagent is mixed with a sample to obtain a first testing sample, and then a second reagent is mixed with the first testing sample for a further reaction to get a second testing sample for basophil classification and/or HGB measurement. A blood sample may be tested in one reaction cell through time-division multiplexing technology to obtain four groups leukocytes classification result and HGB result by single detection channel. Thus, the structure of the analyzer may be greatly simplified on the premise of guaranteeing the performance of the analyzer, the size and cost of the analyzer may reduce and a performance-price ratio of the analyzer may increase.

A slurry analysis system (14) for estimating a first characteristic of a slurry (12) having a plurality of particles (18) suspended in a dispersion medium (20) can include a flow restriction assembly (40); a sensor assembly (43) that senses a sensed condition of the slurry (12) as it flows through the flow restriction assembly (40); and a control and analysis system (26) that estimates the first characteristic of the slurry (12) based on the sensed condition. Further, the control and analysis system (26) can select a selected clogging behavior using the sensed condition, and estimate the first characteristic based on the selected clogging behavior.

The principles and embodiments of the present disclosure relate to methods for using terlipressin to treat a patient having impaired renal function associated with liver disease. A method of improving kidney function in an adult patient with hepatorenal syndrome with rapid reduction in kidney function may include determining the patient's acute-on-chronic liver failure (ACLF) grade and baseline serum creatinine level; obtaining a baseline oxygenation saturation (SpO.sub.2) of the patient; administering a dose of terlipressin acetate to the patient by intravenous (IV) injection; and monitoring the patient's oxygenation saturation with pulse oximetry.

Devices, techniques, and processes are disclosed that use electrical impedance to detect of the presence and contents of droplets including cells, nucleic acids, proteins, or solute concentrations in an array of retrievable, trackable, trapped droplets in a fluidic system.

Systems and methods are provided for counting particles in a fluid flow. In an aspect, coordinates of particles are obtained from video data of particles in a fluid, the video data made up of a sequence of image frames. The particle positions are linked in each pair of consecutive image frames of the video data. The linked particle positions are used to calculate particle trajectories through sequential image frames of the video data, and the particles are counted based on the particle trajectory. In another aspect, the particle positons within each image frame are transformed to estimated positions within a common coordinate frame. The estimated particle positions of a particle are grouped into a cluster center, and the particle count is calculated based on the cluster centers.
