Cat Virus Diagnosis: A New Way to Spot FIP

Feline infectious peritonitis (FIP) is a nasty disease caused by a feline coronavirus. Diagnosing this illness can be tricky because the current methods aren't very accurate. A new approach called the FIP Effusion Index has been tested. This method combines a special ratio (albumin-to-globulin) with a count of certain cells (delta total nucleated cells) that can be measured using a machine called the Sysmex XN-1000V. Scientists looked at samples from 50 cats suspected of having FIP. They found that a high count of these cells (∆TNC ≥ 2. 1) strongly suggests FIP, and an even higher count (∆TNC ≥ 4. 9) can confirm the diagnosis. This new method improved the accuracy of diagnosis significantly. It was very sensitive (96. 3%) and specific (95. 7%) for certain values, and even better for others. This new way of diagnosing FIP is much more precise than using just one of the parameters alone. It could also be useful for diagnosing similar coronavirus diseases in both animals and humans.
