Our three are going for blood tests tomorrow!

Here is a recently update FIP article you probably should read:
http://www.winnfelinehealth.org/Pages/FIP_Web_2010.pdf

I note that it says: "Antibody titers are meaningless for diagnosis of FIP or prognosis" and "Antibody titers are poorly correlated with risk of FIP and should not be used to screen healthy cats."

Wow - now that is a really useful article. It would seem that, since the antibody titres are pretty meaningless, it would be better if they actually tested this way:

Quoting from the winnfelinehealth article:
The most effective and practical tool is PCR analysis of feces for the presence of FECV, a test that is not yet widely available. Because shedding of the virus may be intermittent, testing of multiple samples over time is required. Dr. Hans Lutz at the University of Utrecht has shown that PCR on four fecal swabs taken at one‐week intervals can determine the coronavirus‐shedding status of a cat.

I am going to mention this to our vet - it seems to me that it is more important to know whether a cat is "clear" of the coronavirus or whether it is healthy but continually shedding it!

Very interesting read NCarver :nod:
