Abstract
Disclosed is a process of preparing blood spreads for microscopical examination wherein a smooth and homogeneous plasma layer is obtained. A combination of steps including timely fixation for the purpose of cell preservation, producing a cross-linked matrix in the plasma and performing of chemical reactions by diffusing reagents across an interface, are performed for the purpose of stabilizing both the cell shape and the smoothness and homogeneity of the plasma layer, while the fresh and still wet blood spread is immersed in a non-polar, water immisicible, solvent.
