A multiple layer cytometric test card includes a waste channel to receive biological waste from an area of the test card utilized for testing biological samples, a first waste storage compartment in a waste layer of the card having a top and a bottom in relation to an operating vertical orientation of the test card, and a capillary positioned along a vertical length of the first waste storage compartment, the capillary being open to the waste compartment along the vertical length of the waste compartment, wherein the waste channel is coupled to the capillary channel proximate the top of the waste storage compartment.

Capillary groove for isobaric waste entry

A microfluidic cartridge having a microfluidic channel may have at least one surface that has been roughened, etched or otherwise treated to alter its surface characteristics. In some instances, a microfluidic cartridge may have a microfluidic channel that is configured to provide even distribution of a lysing reagent across the channel. The surface may be roughened or etched using a laser, an abrasive, application of a solvent or in any other suitable manner.

Surface preparation for a microfluidic channel

A disposable blood analysis cartridge for analyzing a blood sample including an optical light scattering measurement channel is described. In use, processed sample may be introduced into a sheath fluid channel at an angle, &#x3b1;, of approximately 90 degrees, relative to the direction of flow of the sheath fluid. In addition, delivering the sample from the side into the sheath fluid may facilitate better positioning of the core within the hydrodynamic focusing channel for measurement.
