Aspects and embodiments of the instant disclosure provide a particle and/or intracellular organelle alignment agent for a particle analyzer used to analyze particles contained in a sample. An exemplary particle and/or intracellular organelle alignment agent includes an aqueous solution, a viscosity modifier, and/or a buffer. Embodiments also encompass systems, compositions, and methods for analyzing a sample containing particles. Parrticles such as blood cells can be categorized and counted by a digital image processor. A digital microscope camera can be directed, for example using certain focusing techniques, into a flowcell defining a symmetrically narrowing flowpath in which the sample stream flows in a ribbon flattened by flow and viscosity parameters between layers of sheath fluid. Blood cell images can be collected and analyzed using dynamic range extension processes and systems.

Hematology systems and methods

The present disclosure relates to a staining methodology employing a particle contrast agent composition capable of rapidly staining cells in a single step. The particle contrast agent composition can be comprised of a combination of one or more particle contrast agents and one or more permeabilizing agents, optionally including one or more fixing agents and other components. The particle contrast agent composition can include Crystal Violet, 5PD-Lytic, and Proclin 300.
