Virbac Speed Trio FeLV/FIV/Corona Combined detection test for circulating FeLV antigens & anti-FIV antibodies and anti-Feline Corona Virus antibodies in cats

Virbac Speed Trio FeLV/FIV/Corona Combined detection test for circulating FeLV antigens & anti-FIV antibodies and anti-Feline Corona Virus antibodies in cats

Product Overview and Diagnostic Utility

Speed Trio FeLV/FIV/Corona is a combined diagnostic test for the simultaneous detection of circulating Feline Leukemia Virus (FeLV) antigens, anti-Feline Immunodeficiency Virus (FIV) antibodies, and anti-Feline Coronavirus (FCoV) antibodies in cats.

• Target Species: Cats.
• Sample Efficiency: Requires only 3 drops of sample to test for three feline viruses.
• Speed and Convenience: Quick and easy to use, providing results for 3 conditions in just 15 minutes.
• Diagnostic Value: Enables comprehensive assessment of a cat's immune status during routine consultations or when clinical suspicion exists.
• Usage Restriction: For veterinary use only.

Clinical Background and Testing Rationale

• FeLV and FIV Dynamics: Both retroviruses cause non-specific and highly variable symptoms, preceded by an asymptomatic phase of varying duration. Biological testing is essential for differential diagnosis, and regular screening is the primary strategy for viral management, with regional prevalence ranging from 1 percent to 20 percent.
• FeLV Antigen Detection: Testing for soluble FeLV antigens identifies viremic status even in cases of low viral load, such as early infection, transient viremia, or sequestered infection. Note that antigen tests may be negative during latent infection.
• FCoV Antibody Detection: Measuring anti-FCoV antibodies helps guide preventive measures and management in multi-cat environments. A positive result indicates exposure and antibody development, with seroconversion typically occurring 7 to 28 days post-infection. The test does not distinguish between the mild enteric strain and the pathogenic FIP strain, nor does it confirm an active infection.

Indications for Use and Clinical Applications

• Speed Trio FeLV/FIV/Corona is recommended in the following scenarios:
• Screening healthy cats with or without known medical history prior to vaccination, sterilization, breeding, or introduction into a multi-cat group, helping guide the isolation of exposed individuals.
• Confirming or ruling out retroviral exposure when clinical suspicion exists.
• Combining with other biological tests to enhance diagnostic precision and reduce the hypothesis of Feline Infectious Peritonitis (FIP) in symptomatic cases.
• Combining with complementary diagnostics to monitor retroviral progression over time and identify latent versus active stages.
