PROBLEM
BLOCK/SLIDE
POSSIBLE CAUSES
RIMEDIAL ACTION
Specimens partially or
completely
detached
from
surrounding
WAX.
Tissue block surface appears
to collapse “Dry back” and
samples appear partially or
completely detached from
surrounding WAX when the
tissue is observed the next
day.
Tissue block very difficult to
section.
1.
Processing time is inadequate for the
tissue size selected, resulting in
incomplete dehydration/clearing and
WAX impregnation.
Tissues that retain any of the solvent will
escape by next day, producing this effect,
varying according to the size.
1.
Select the correct processing time, or
select longer processing time for the
sample size.
