A method of analyzing a blood sample from a subject includes loading the blood sample into a single chamber; acquiring, via an imaging system, a stack of serial focal plane images of the blood sample from a plurality of fields of view of the chamber; creating a virtual three dimensional image of the blood sample from selected ones of the stacks of serial focal plane images; and analyzing the virtual three dimensional image to identify blood formed elements within the blood sample. Identifying blood formed elements within the blood sample may include identifying a type and amount of white blood cells, and/or identifying an amount of red blood cells and/or hematocrit, and/or identifying an amount of platelets. Identifying blood formed elements within the blood sample may include determining numbers and percentage by volume in the blood sample of one or more types of white blood cells.

Rapid mobile screening and triage for infections and infection severity

The present invention provides a method of identifying an animal for which antibiotic treatment, anti-infective treatment, probiotic treatment, immunostimulant treatment, additional monitoring and/or a separate or alternative management strategy is appropriate, comprising: a) collecting a sample from said animal; b) performing a leukocyte differential cell count on said sample; c) comparing said leukocyte differential cell count of (b) with an index of infection; and d) initiating antibiotic treatment, anti-infective treatment, probiotic treatment, immunostimulant treatment, additional monitoring and/or a separate or alternative management strategy of said animal on the basis of said comparing step.

Methods and compositions for reducing antibiotic administration to farm animals

A device tethering system is provided for securing a device to a source location as may be assisted by a tether. The device tethering system may include a retraction component, tether, pouch, belt, device mounting component, device aspect of the device mounting component, and/or tether aspect of the device mounting component. A method for securing a device to a source location using the device tethering system is also provided.

Device tethering system and method

The present invention relates to a device and method for the detection of mastitis or other disease from a body fluid of a mammal for example from cow's milk. The device and method relates to a wedge microfluidic chamber for using a minimal amount of fluid and being able to use the device to observe leukocytes in a mono-layer for the purpose of disease detection, cell counts or the like.

Microfluidic chamber assembly for mastitis assay

An automated microscope apparatus, comprises an outer housing having an external wall; optionally but preferably an internal wall in said housing, and configured to form a first compartment and a separate second compartment in said outer housing; a microscope assembly in said housing, preferably in said first compartment; and a microprocessor in said housing, preferably in said second compartment; and optionally but preferably a heat sink mounted on said housing external wall, preferably adjacent said second compartment, with said microprocessor thermally coupled to said heat sink and operatively associated with said microscope assembly.

Diagnostic apparatus

The present invention relates to an leucocyte antigen mediated microfluidic assay and a microfluidic device for analyzing a subjects' body fluids containing leucocytes to determine if the subject has been previously exposed to a predetermined antigen.

Microfluidic device and leucocyte antigen mediated microfluidic assay

A collection device includes a base housing member having at least one chamber. A cover housing member has at least one aperture therein, and the cover housing member is configured to cover the base housing member such that the at least one aperture is positioned in fluid communication with the at least one chamber. The cover housing member includes a cartridge holding interface configured to releasably engage with a cartridge that is configured to cover and receive a fluid from the at least one chamber via the at least one aperture.

Sample collection and transfer assembly and related methods

An automated microscope apparatus comprises an outer housing having an external wall; optionally but preferably an internal wall in the housing configured to form a first compartment and a separate second compartment in the outer housing; a microscope assembly in the housing (preferably in the first compartment); a microprocessor in the housing (preferably in the second compartment), and (optionally but preferably) a heat sink mounted on the housing external wall, preferably adjacent the second compartment, with the microprocessor thermally coupled to said heat sink and operatively associated with the microscope assembly. Systems and methods employing the same are also described, along with component parts thereof.

A device for detecting at least one analyte in a liquid sample generally comprises (i) a support having a chamber for receiving a biological fluid (e.g., milk) therein, wherein said chamber is an elongate chamber having a length axis; (ii) a (stationary or movable) carrier (in some embodiments in the form of an end cap, or connected to an end cap; in other embodiments in the form of an agitator in said elongate chamber).

Rapid detection of analytes in liquid samples

A device for detecting at least one analyte (and in some embodiments two, three, or four or more different analytes) in a liquid sample generally comprises (i) a support having a chamber for receiving a biological fluid therein, wherein said chamber is an elongate chamber having a length axis; (ii) a carrier or agitator in said elongate chamber, said carrier or agitator having opposite end portions and a side portion, the carrier or agitator dimensioned to travel in said chamber along said length axis and/or permit said liquid sample to flow in the chamber therearound, either (or both) thereby agitating the liquid sample; and (iii) at least one anti-analyte antibody coupled to either the carrier and/or the chamber side wall.

Sample collection device assembly

Target nucleated cells, and target cells containing remnant ribosomal material, which are present in a quiescent anticoagulated whole blood sample are optically detected, enumerated, and analyzed in a sample chamber that has a varying through plane thickness due to convergent opposing sample chamber walls. At least one of the convergent walls of the chamber is transparent so that the blood sample can be observed. The chamber's varying thickness produces a first lesser thickness region in the chamber wherein individual red cells and quiescent monolayers of red cells in the sample will reside after the sample is introduced into and fills the chamber. Larger formed constituents such as white blood cells and nucleated red blood cells present in the sample will reside in greater thickness regions of the chamber, and non-nucleated red cells which reside in such greater thickness regions will agglomerate to form rouleaux. By admixing fluorescent dyes with the blood sample, target cells in the sample can be enumerated and differentiated by means of a scanning instrument which is able to measure different wave length color signals emitted from the target cells in the sample, and differentiate the target cells one from another by reason of the nature of the emitted color signals.
