Dear X: For what it is worth, I have some serious misgivings about the current reliability of the Avecon saliva test, and I do not currently recommend its use. There have been a number of false negatives with this test, and it has recently shown poor correlation with Avecon blood tests in the hands of owners and shelter operators. Whether it is a sample problem, a testing problem, a problem with the components, or something else, there are simply too many variables with it to rely on it. Regarding the available blood test, the CIEP test has many years of successful use and independent confirmation of its reliability. Currently, the leaders in research in this field, Drs. Bloom and Stevenson, preferentially use it over an ELISA test. Regarding the ELISA blood test by Avecon Diagnostics - the initial testing regimen was fairly small and there were a number of false negatives. Testing appears to be continuing at Avecon, but the proper time for this testing is before a product goes to market, not afterward. I suggest that of the Avecon options, this one probably has more merit, but I would caution, as I have in the recent past, that all positive ELISA tests be confirmed by the CIEP test. I am hopeful that Avecon will soon answer the continuing questions on the product. As a positive serologic titer for ADV is almost akin to a death sentence for a ferret, I believe that all possible options should be exhausted before declaring an animal positive.
