Feline Infectious Peritonitis (FIP) is a challenging disease to diagnose since its symptoms can be similar to those of other feline diseases. Additionally, there is no single definitive test for FIP, and a combination of clinical signs, blood tests, and diagnostic imaging may be needed for an accurate diagnosis.
Here are some steps that veterinarians typically take to diagnose FIP:
Physical Examination: The veterinarian will perform a complete physical examination of the cat, looking for symptoms that may indicate FIP, such as fever, lethargy, weight loss, and abdominal distention.
Blood Tests: Blood tests can help diagnose FIP by measuring specific antibodies against the virus or looking for other changes in the blood, such as increased white blood cell count, decreased red blood cell count, or increased liver enzymes.
Diagnostic Imaging: Radiographs (X-rays) or ultrasound imaging may be performed to look for fluid accumulation in the abdomen or chest.
Fluid Analysis: If fluid accumulation is present, the veterinarian may collect a sample of fluid from the abdomen or chest for analysis. The fluid from cats with FIP often has high protein levels and a distinctive appearance.
Polymerase Chain Reaction (PCR) Test: This test can detect the presence of the virus in the blood or body fluids. However, it is not always reliable since it may detect the virus in cats that are not infected with FIP.
It is important to note that the diagnosis of FIP can be challenging, and sometimes a definitive diagnosis may not be possible. If you suspect that your cat may have FIP, it is important to seek veterinary care as soon as possible.
