I had a recent situation where there was a slim chance that my house had been exposed to ADV. I decided to use United, not so much because I didn't trust the Avecon test, but because they had all been tested with the Avecon test more recently than the United test. In light of recent results from other shelters and owners, I decided to see if I would end up with the same mixed bag. I'm pleased to say that I didn't, and all of my results from both tests match and are negative. Here is the scoop in more detail... I sent in blood to United last week on every ferret in my home. All 24 came back negative. All 24 have also tested negative at least once on the Avecon saliva test. Of the 24, 12 had previously tested negative on the United test at least one other time. Of the 24, 16 have been tested by Avecon, always by saliva but on both tests (the ELISA and POCT) and were always negative. In four cases they have been tested four or more times each, and each time they tested negative. The ferret who has been in my house the longest has been tested numerous times (I've lost count, but a dozen or more) with all three (United, Avecon POCT and Avecon Elisa) and has always tested negative. If anyone wants more info, feel free to ask. Anne [Posted in FML issue 3729]
