Morphological Parameters of Patients of Blood Suffering from Tuberculosis

The subtle changes in the physiology of erythrocytes at the cellular level on documented in the present laser diffraction study. Using this technique one can differentiate the morphologies of erythrocytes. The size and shape of blood cells are determined usually by microscope. This method, besides being tedious, cannot be extended to a large number of cells and samples. In view of this, a simple and quick method has been developed for determining the average size and shape of blood cells by employing laser diffraction technique. Blood samples were collected from normal healthy persons and patients from tuberculosis. The laser diffraction method is very rapid and simple for assessing the average size of the cells. This could also be used with advantages as a diagnostic tool for assessing the variation in the size of human RBC.
