Subject: Re: [Ferret-Health-list] Re: Titers
             I did converse with a vet Dr. XXXXX XXXXXXXXX in TX a while back  and the 
labs CAN read whether the titers show: exposed to the virus, post 
vaccination , shedding virus , etc.  There is a way to differentiate the 
readings -- but I guess it is whether the lab is capable!  Perhpas the 
folks at United could provide this information as I am sure it was 
discovered in the rating sTudies which preceded the USDA approval!
