Simple Practical Test To Detect Or Exclude FIP Infection

Test applicable to: Cat
Sample: Abdominal or pleural effusion material

The RIVALTA FIP-VETube test is a simple, fast, on-site test which allows the veterinarian to detect or exclude an ongoing FIP ( Feline Infectious Peritonitis) infection with a high degree of reliability and is suitable for use in any veterinary practice.

Aid to Differentiate Cause of Effusion

The test is an aid to differentiate between effusions caused by FIP (exudates) and those caused by other diseases (transudates).

Test Principle

Protein in the effusion is detected by adding a drop to the aqua-acetic acid mixture. This can be observed by the characteristic formation of more or less stable precipitation products or cloudy mists, forming drops or smears. In contrast, a transudate completely dissolves during sinking in the aqua-acetic acid mixture.

The Rivalta test is not pathognomic for FIP but nevertheless has a very good sensitivity of 98% (high negative predictive value) and a specificity of 80%. Positive Rivalta tests can occur in cats with bacterial peritonitis or lymphoma although these conditions are usually easy to differentiate between using other tests.

There are many other different laboratory tests available to aid in the diagnosis of Feline Infectious Peritonitis (FIP).

Tests which aid the diagnosis of Feline Infectious Peritonitis

  • Direct detection of Feline Coronavirus (FCoV) in macrophages by PCR.
  • Indirect detection of anti-FCoV antibodies using rapid tests and/or indirect immunofluorescence tests (IFT).
  • Screening of effusion (e.g. by the Rivalta test, biochemical and cytological tests).

All these tests together with other biochemical and cytological tests have an important role to play in the final diagnosis of FIP.

Why Test?

Why is it important to test for Feline Infectious Peritonitis?

Feline Infectious Peritonitis is a potentially infectious disease in domestic cats as well as other members of the cat family.  It is not an age-specific disease although it is more common in younger cats, especially those two years or less in age.  It is not a common disease but Feline Infectious Peritonitis can be fatal if it is contracted by the animal.


What are the symptoms of Feline Infectious Peritonitis?

The clinical symptoms of the disease can vary from cat to cat. However, if a cat is infected with Feline Coronavirus (FCoV) then it may be healthy or show only mild symptoms of possible Feline Infectious Peritonitis.

Cats developing or with FIP can develop the following symptoms

Mild Signs can be either:

  • Weight loss
  • Undulating fever
  • Depression
  • Anorexia

If FIP develops it can be in an effusive (wet) form which is characterised by polyserositis or vasculitis. If FIP is in a non-effusive (dry) form then it can be characterised by granulomatous lesions present in many of the animals’ organs, lymph node enlargement and then choric diarrhoea.

Extreme signs can be either:

  • Ocular–uveitis, keratic in the anterior eye chamber, retinal perivascular cuffing, chorioretinitis or even pyogranulomatous chorioretinitis.
  • Neurological signs are hyperaesthesia, behavioural changes, cranial nerve defects, nystagmus seizures or even ataxia.
