When she says "bloodwork" I wonder what she means. You can take blood and send it to a lab where they perform the same type of ELISA test as done in the vet's office, but they do it differently at the lab (my vet called it a "well test"). They have to take a bigger blood sample for that. It's still an ELISA test, which looks for small fragments of the virus in the bloodstream, but a little more reliable than doing it with the snap test kit.
Then there's the IFA test which is a totally different test and it looks for the virus in the white blood cells/bone marrow. If by "bloodwork" she means the IFA test then it's very possible that it's negative and the combo test is positive and that doesn't mean the combo test is wrong. The combo test could be right but the virus just hasn't progressed into the bone marrow. So when she says "bloodwork" it's hard to know for sure whether that means the combo test was right or wrong. I'd like to know because if she's talking about two ELISA tests (one done in the vet's office with a snap test kit and one sent to the lab) and they keep coming up differently then there's definitely a problem with the snap test kits. “I am not interested to know whether vivisection produces results that are profitable to the human race or doesn’t….the pain which it inflicts upon unconsenting animals is the basis of my enmity toward it, and it is to me sufficient justification of the enmity without looking further.” – Mark Twain From: korruptaki...@gmail.com Date: Tue, 6 Dec 2011 14:14:02 -0800 To: email@example.com Subject: [Felvtalk] Very Scary Testing results! Very scary.. see below.. ------Original Message------ From: Ellen Fawl To: rescuealliancew...@yahoogroups.com Subject: Scary FELV test results! Sent: Nov 22, 2011 11:16 PM I need to share this so it can get to the FELV Lists and whomever is following this testing debacle. We took in 5 Persians last week. We had them combo tested with the standard Snap test. All five tested positive. We had blood work done on one cat and it came back negative. We assumed the tests were done wrong so they redid them two days ago. All four remaining cats tested positive AGAIN. We had blood work taken on all four, sent it in, and all four came back negative. This is really scary stuff. Cats are killed all the time because they test positive. Had we heard about these cats being in a shelter & testing positive it's not likely we could have taken them in. The vet office in Santa Cruz is going to follow up with the company, but if there is anyone else out there tracking this stuff, I want to get the information to them.
