Specimens with Spontaneous Clots: Preparation

To make a cell block from clotted material:

  1. Squeeze all of the extra liquid out from the clot with wooden applicator sticks until a solid mass is achieved. Rolling the mass around two applicator sticks while pressed against the side of the container is often the easiest way (see Figure 3).
