Determination of undeformable erythrocytes in blood samples using laser light scattering

Abstract: Using laser light scattering a rapid method for estimating relative counts of less deformable erythrocytes in blood samples was developed. The procedure is based on comparison of light scattering from blood cells deformed in defined shear stress and blood cells at rest, respectively.

“…Furthermore, the analysis of the photographs turned out to be time consuming and difficult to standardize [12]. In a study of Plasek and Marik the latter problem was recognized [13]. They tested a method to obtain the fraction of poorly deformable cells from the intensity at one single position in the intensity pattern.…”

“…Moreover, few experimental setups have been used for in vivo or in vitro blood measurements which focused on the light-absorbing properties of blood. The correlation between the obtained patterns and the physical characteristics of blood, such as the concentration of hemoglobin and the degree of oxygen saturation, is determined with the aid of simple multiplescattering theories when dilute suspensions of blood are used [2][3][4]. More complicated multiplescattering mathematical models are used when measurements in concentrated suspensions of blood or a whole-blood medium are available [5][6][7][8].…”
