Diagnosis

Diagnosis

The Feline Leukemia Virus (FeLV) is a serious and potentially fatal disease that affects cats. Early diagnosis and treatment are crucial for managing the virus and improving the cat’s health.

Blood Tests

There are two main blood tests used to diagnose FeLV:

  • ELISA (Enzyme-Linked Immunosorbent Assay): This test detects antibodies against FeLV in the cat’s blood. If antibodies are present, it means that the cat has been exposed to FeLV and may be infected.
  • PCR (Polymerase Chain Reaction): This test detects the FeLV virus itself in the cat’s blood. It is more accurate than ELISA, especially in early stages of infection or in immunosuppressed cats.

Antibody Detection

The ELISA test detects antibodies produced by the cat’s immune system in response to FeLV infection. If the test is positive, it indicates that the cat has been exposed to FeLV and has developed antibodies. However, it does not distinguish between active and past infections.

Viral Load Quantification

The PCR test detects the amount of FeLV virus present in the cat’s blood. A high viral load indicates an active infection. This test is particularly useful in diagnosing FeLV in kittens or immunosuppressed cats, where antibody production may be impaired.

Interpretation of Results

  • Negative ELISA and PCR: The cat is not infected with FeLV.
  • Positive ELISA and negative PCR: The cat may have been exposed to FeLV in the past but has cleared the infection.
  • Negative ELISA and positive PCR: The cat is actively infected with FeLV.
  • Positive ELISA and positive PCR: The cat is actively infected with FeLV and has a high viral load.

It’s important to note that a negative FeLV test does not guarantee that the cat is not infected. Some cats may test negative early in the infection or if they are immunosuppressed. Therefore, it’s recommended to retest suspected cats after a period of time.

Veterinarians may also recommend additional tests to determine the stage and severity of the FeLV infection, such as a physical examination, bone marrow aspirate, or lymph node biopsy.

Treatment

Feline Leukemia Virus (FeLV) is a retrovirus that infects cats and weakens their immune system. While there is no cure for FeLV, supportive care can help improve the quality of life of affected cats and manage secondary infections.
