Mike,
This is from our manual. It might help.

Definitions
Sometimes a pathologist may request more sections to
be cut from a block. 
The following definitions are a guide only and will
depend on the type and thickness of the tissue in the
block.

RECUT:    
„X This may be requested because of a poor initial
section (eg not deep enough, poor staining, lifting)
„X Cut a better section (deeper or use an adhesive if
required).

SERIAL SECTIONS:
„X Cut consecutive sections WITHOUT trimming.

LEVELS:   
„X Trim in 30um and then section

DEEPER:   
„X Trim in 100um and then section.


REMEMBER it is always better to not trim too far than
to trim it all away.

If in doubt cut levels anyway.
