Optical Investigation of Individual Red Blood Cells for Determining Cell Count and Cellular Hemoglobin Concentration in a Microfluidic Channel

Micromachines, 2021
We demonstrate a blood analysis routine by observing red blood cells through light and digital holographic microscopy in a microfluidic channel. With this setup a determination of red blood cell (RBC) concentration, the mean corpuscular volume (MCV), and

Accuracy of capillary blood for the determination of packed cell volume and anemia among pregnant women in Enugu, Nigeria

International Journal of Medicine and Health Development, 2017
Background: Venous blood packed cell volume (PCV) in pregnancy differs from capillary blood PCV. How this disparity affects the accuracy of capillary blood in determining the actual (venous) PCV is not clear.

Droplet impact of Newtonian fluids and blood on simple fabrics: effect of fabric pore size and underlying substrate [PDF]

, 2020
When a droplet impacts a fabric mesh at a sufficiently high impact velocity, it not only spreads over the fabric but also penetrate its pores. To determine the influence of this liquid penetration of the fabric on droplet spreading on thin fabric meshes, we measured the droplet spreading ratio on fabric with and without an underlying substrate using a ...
