If there will be delay of more than two hours, place brush in 5-10 mL saline to rinse.  If possible, gently vortex specimen container with brush inside to dislodge an optimal amount of cellular material.  Remove brush and add 30 mL of Cytolyt or an equal volume of 50% ethyl alcohol to the saline rinse.
