System and method for determining an immune activation state
A method and/or system can include processing a blood sample of a patient by degrading red blood cells of the blood sample using a lysing solution, quenching the degradation of the red blood cells after a threshold lysing time, centrifuging and aspirating the quenched solution to remove degraded red blood cell debris and concentrate white blood cells of the blood sample, and suspending the concentrated white blood cells in a buffer solution; within a threshold transfer time, deforming white blood cells, of the suspended white blood cells, within a microfluidic chip; and determining a probability that the patient is in an immune activation state based on images of the white blood cells acquired while deforming the white blood cells.

ALIGNING A NON-SPHERICAL BIOLOGICAL ENTITY IN A SAMPLE FLOW USING AMBIENT VISCOELASTIC FLUID FLOWS
A technique is presented for aligning, in a desired region within a flow chamber of a flow cell, a non-spherical biological entity carried in a sample. The flow chamber has a rectangular cross-section. A bottom flow input module, a top flow input module and a sample input module provide a viscoelastic first fluid, a second viscoelastic fluid, and the sample, respectively, to the flow chamber. The first and the second viscoelastic fluids laminarly flow along a bottom and a top wall of the flow chamber and the sample laminarly flows sandwiched between them. By controlling rate of flow of the first and/or the second viscoelastic fluids the sample flow, and thus the non-spherical biological entity, is focused in the desired region. A gradient of sheer within the sample flow set up due to the first and second viscoelastic fluids orients the non-spherical biological entity in the desired region.
