Just what type of way do you want to "distinguish" Abeta and C fibers?
They are very different in many respects.  You can see the difference
in fiber diameter and myelination in anatomical preparations.  You
can measure the difference in conduction velocity (and ease of
stimulating and recording) in physiological preparations.  They
respond to very different sensory modalities.  They connect to
very different central pathways.  All of these can be involved in both
experimental and clinical observations.
