Features & Benefits

The KVP FeLV FIV Pro™ Test is a fast, accurate, and reliable in-clinic diagnostic tool designed to detect two of the most serious feline viruses: Feline Leukemia Virus (FeLV) and Feline Immunodeficiency Virus (FIV). This 2-in-1 lateral flow assay identifies FeLV antigen and FIV antibody using just one drop of whole blood, serum, or plasma; delivering clear results in only 5 to 10 minutes.

Ideal for veterinary clinics, shelters, and mobile practices, this feline combo test requires no special equipment or training. It’s a practical solution for routine screenings, pre-adoption testing, or evaluating symptomatic cats. With high sensitivity and specificity (98% sensitivity and 99% specificity for FeLV; 98% sensitivity and 97% specificity for FIV), the FeLV FIV Pro™ Test gives veterinary teams confidence in their diagnosis and helps guide treatment, isolation, or rehoming decisions.

Each kit includes all necessary components: test cassettes, assay buffers, droppers, and EDTA tubes, making it easy to integrate into your workflow and support early detection and care.

How To

1.Collect Sample
Draw whole blood from the cat and transfer to the provided EDTA tube. You may also use serum or plasma.

2.Prepare the Test
Open the foil pouch and place the test cassette on a flat surface. Use the kit within 10 minutes of opening.

3.Apply Sample and Buffer
Add 1 drop (20 µL) of whole blood, serum, or plasma into the FeLV and FIV sample wells. Immediately add 4 drops (100 µL) of the corresponding assay buffer into each well.

4.Wait for Results
Allow the test to develop for 5 to 10 minutes. Do not interpret results after 10 minutes.

5.Read the Results
Positive: Both control (C) and test (T) lines appear Negative: Only the control (C) line is visible Invalid: No control (C) line appears—repeat the test with a new cassette
