             I can't get to it right now, but ferret liver values can be a bit 
confusing so in 
http://www.afip.org/ferrets/index.html
there is a section that can help with interpreting them.  I think that 
it is within a section titled something like "Things Every Vet 
should Know" .   Worth seeing in case there are conclusions 
being drawn from aspects that mould look abberent for a cat or 
dog but are fine for a ferret.
Given the tarry stools have you considered ulcers?  There is a lot 
in past posts on handling those.  The search engine at 
http://groups.yahoo.com/group/Ferret-Health-list
will find you a weath of info.
