Clinical Presentation
FIP manifests in two primary forms: wet (effusive) and dry (non-effusive). Clinical signs vary depending on the form and affected organs, including fever, lethargy, weight loss, anorexia, and respiratory or neurological symptoms. While suggestive, these signs are not specific to FIP and overlap with other feline diseases. This non-specificity underscores the need for further diagnostic testing, including antibody level assessment.
-
Serology: Antibody Titers
Serological testing measures antibodies against feline coronavirus. While high antibody titers can be suggestive of FIP, they are not definitive. Many cats exposed to feline coronavirus do not develop FIP, and some cats with FIP have low titers. Interpretation of titers must consider other factors like vaccination history and clinical presentation. A calculator or chart can aid in interpretation but requires contextualization within the overall diagnostic picture.
-
Diagnostic Imaging
Radiography, ultrasound, and CT scans can reveal characteristic changes associated with FIP, such as fluid accumulation in the abdomen or chest (wet FIP) or granulomatous lesions in various organs (dry FIP). Imaging findings, while helpful, are rarely pathognomonic for FIP. They provide supportive evidence, enhancing the diagnostic value of other tests, including serology.
-
Polymerase Chain Reaction (PCR)
PCR can detect feline coronavirus genetic material in fluid or tissue samples. However, PCR positivity alone does not differentiate between FIP and other coronavirus infections.

4. Titer interpretation
Titer interpretation is intrinsically linked to the utility of an FIP titer calculator. The numerical value generated by such a calculator represents the concentration of antibodies against feline coronavirus, but this value requires careful interpretation to provide clinically relevant information. A high titer does not automatically equate to an FIP diagnosis. For example, a cat exposed to a less virulent strain of feline coronavirus, or even a previously vaccinated cat, could exhibit a high titer without having FIP. Conversely, a cat with FIP, particularly in the dry form, might exhibit a low or even negative titer. Therefore, titer interpretation hinges on understanding the limitations of serology and integrating results with other diagnostic findings.
The practical significance of accurate titer interpretation lies in its ability to guide diagnostic and therapeutic decisions. Consider a scenario where a cat presents with vague symptoms like lethargy and weight loss. A high titer, while concerning, requires further investigation. Imaging studies revealing fluid accumulation in the abdomen, combined with the high titer, significantly increases the likelihood of an FIP diagnosis. In contrast, if imaging reveals no abnormalities, the high titer might simply indicate prior exposure to a coronavirus, necessitating investigation of other potential causes for the observed symptoms. Therefore, titer interpretation serves as a component within a larger diagnostic puzzle, its value maximized when integrated with a comprehensive clinical picture.
Challenges in titer interpretation arise from the complex relationship between antibody levels and FIP. The variability in immune responses, the influence of vaccination, and the differing presentations of FIP contribute to the difficulty in establishing definitive diagnostic thresholds.
