I know of no adequate substitute for glutaraldehyde as a fixtive for
EM. I do know of substitutes that are much *more* hazardous, but none
that are less troublesome.
For many high-resolution TEM and SEM procedures of cultured cells
(therefore probably not applicable in clinical settings), glut can be
used without formalin. I wouldn't want to try the vice-versa, though.
I don't see why the inspection agency or your pathologist would get
their knickers in a knot over glut. Any self-respecting histology or
microscopy facility has much worse chemicals on its shelves.
