The Rivalta Test for FIP

This is how the Rivalta Test is done: https://www.youtube.com/watch?v=XmOk2veunqA&fbclid=IwAR0iaN0Le0YEGA84IQUcm85hIYFES74gTTdDdISeBHngWvRERHC0aTqqwLU

I got this from the FIP Advisory Group. They have been so helpful.

If the “jellyfish” appears – that’s a “positive” result and it means the cat has an 86% chance of having FIP.

If the effusion diffuses into nothingness, no “jellyfish” – that’s a “negative” result and it means the cat has a 97% chance of NOT having FIP.

Today, the test was done on Zurik’s effusion but the vet said it was invalid because the vinegar was too diluted.

According to the video, an 8% vinegar solution is needed. A few drops of vinegar into a test-tube of water, then just ONE drop of the pleural effusion into it.

And HOPE, hope, hope that no jellyfish appears.

Till tomorrow then…

Meanwhile, EAT to your heart’s content, Mr Zurik!!

Eat and be merry!!

P.S. I also learnt from the group that there is no point in doing the FIP-antigen test on the effusion since it’s been done on the blood. The FIP-antigen test on the effusion is not reliable at all.  So, we will not be doing this test tomorrow.  Just the Rivalta Test then.  There is only one reliable test on the effusion and it’s called the FCoV RT-PCR. We do not have this test for the public in Malaysia. Another test which can only be done in the laboratory is the immunochemistry staining test. Again, not available to the public in Malaysia.
