Controlled dispensing of samples onto substrates

Methods for dispensing a fluid sample on a substrate include obtaining an image of a sample applicator in proximity to the substrate, where the image includes a first image of the sample applicator and a second image of the sample applicator, determining a height of the sample applicator relative to a surface plane of the substrate based on a distance between common portions of the first and second images, and dispensing the fluid sample onto the substrate using the sample applicator, where the dispensing includes: translating the sample applicator, translating the substrate, or translating both the sample applicator and the substrate to effect a relative translation between the sample applicator and the substrate; and maintaining the sample applicator within 2 microns of a target height relative to the surface plane of the substrate during the translating.. . ...

Imaging blood cells

This document describes methods, systems and computer program products directed to imaging blood cells. The subject matter described in this document can be embodied in a method of classifying white blood cells (wbcs) in a biological sample on a substrate. ... Roche Diagnostics Hematology Inc

Systems and methods for analyzing body fluids

Systems and methods analyzing body fluids contain cells including blood, bone marrow, urine, vaginal tissue, epithelial tissue, tumors, semen, and spittle are disclosed. The systems and methods utilize an improved technique for applying a monolayer of cells to a slide and generating a substantially uniform distribution of cells on the slide. ... Roche Diagnostics Hematology Inc

Measuring volume and constituents of cells

A method for determining a mean cell volume for a blood sample includes: illuminating the sample with incident light at a plurality of illumination wavelengths and obtaining a two-dimensional image of the sample at each of the plurality of illumination wavelengths; identifying a plurality of cells that appear in each of the images; for each one of the plurality of cells, determining an integrated optical density corresponding to each of the plurality of illumination wavelengths; for each one of the plurality of cells, determining a cell volume based on the integrated optical densities corresponding to each of the plurality of illumination wavelengths; and determining the mean cell volume for the blood sample from the cell volumes for each one of the plurality of cells.. . ...

Fluid sample preparation systems and methods

Sample application systems can include an extraction mechanism to remove a sample from sample containers, a sample vessel disposed on a deployment mechanism, where the deployment mechanism is arranged to move the sample vessel to receive a sample, an extraction mechanism washing station to wash the extraction mechanism, a sample applicator to remove a portion of the sample in the sample vessel and apply it onto a sample carrier, where the deployment mechanism can move the sample vessel to a sample application position, a sample vessel washing station to wash the sample vessel, where the deployment mechanism can move the sample vessel to the sample vessel washing station, a sample applicator washing station to wash the sample applicator after the sample has been dispensed onto the sample carrier, and a fluid control system to control flow of a fluid provided to the extraction mechanism and the sample applicator.. . ...
