My Annie was never positive until her owner went into hospice and she ws locked up in her trailer for 3 weeks, not knowing where Kathy was and only Kathy's sister coming in, changing the box and giving fresh water and food, no interaction. Then when I said I would take her (Kathy said if no good home, pout to sleep) they put her in a cardboard box, brought to vet's office and I put her in my carrier and took her home to suddenly have to deal with 2 strange people and another cat. Then she tested positive. I think stress has a great deal to do with the onset of FELV. She was 4 when I got her and is now going on 9, healthy as can be. I keep my other cats vaccinated for FELV. All are healthy except for Lil Bit who is now dealing with extreme bacteria infection in bladder, most likely kidneys. Has nothing to do with Annie being FELV. Lil Bit is now on the road to recovery I think. Still wobbly, but her eyes are not dialated, she is eating (a little bit at a time because the first time she wanted food, gulped it down and up=chucked). Now I let her eat a bit, make her rest a bit and on till she wants no more. No more problems with up-chucking. She is getting sub q fluids every other day and has been drinking. I think part of her stumbling around in circles is she wants to get to the watr fountain. When I let her out yesterday, she headed straight for it and began drinking. Water in a bowl is ok, but fountain is better. ---- Margo <toomanykitti...@earthlink.net> wrote: > > Hi Shelley, > > This is coming from a very disgruntled person so take it all with a > grain of salt:) > > I have pretty much given up on test results as accomplishing > anything.

A PCR test can also be run to help resolve any conflicts in the tests. PCR is very sensitive, so a negative test result run by a reputable laboratory indicates infection is unlikely. However, because PCR testing is very sensitive to laboratory error, correct sample handling and laboratory quality are extremely important." > > > Even so, the more I read, the less I trust ANY test to be accurate.
