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.

The Use of Portal Vein Pulsatility to Differentiate Hypervolemic and Hypovolemic Hyponatremia

Case Reports in Critical Care, 2019
Hypotonic hyponatremia is a common electrolyte disorder defined by a blood serum sodium value of less than 136 meq/L. A challenge in managing hyponatremia is accurately determining the etiology for the free water excess as management can markedly differ.
