Touch Preparation/Impression Smear

17
Q

A smearing technique where using an applicator stick, the material is rapidly and gently applied in a direct or zigzag line throughout the slide to obtain a uniform distribution.

18
Q

A selected portion of the material is transferred to a clean slide and gently spread into a moderately thick film by teasing the mucous strands with an applicator stick.

19
Q

It is done by placing a drop of secretion or sediment upon one slide and facing it to another clean slide

A

Pull-Apart Technique

20
Q

A special method where slide surface is in contact and pressed on the site
