Feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV) infections are two main causes of illness and death in cats.
The RIDX^® FeLV Ag/FIV Ab Combo Test Kit is a lateral flow chromatographic immunoassay for the qualitative detection of FeLV antigens and FIV antibodies in feline blood. This kit shows two letters which are the test (T) line and the control (C) line for each test on the surface of the device.
• FeLV Ag Test: If FeLV antigens exist in the sample, that bind to the gold-conjugated FeLV antibody. The antigen-antibody complex moves through the membrane by capillary force and responds to the FeLV antibody on the test line, resulting in a red line. The highly selective and sensitive monoclonal antibody to FeLV is used as a capture and detector in the kit.
• FIV Ab Test: If FIV antibodies exist in the sample, that bind to the gold-conjugated protein A. The complex moves through the membrane by capillary force and responds to the FIV antigen on the test line, resulting in a red line. The high-quality recombinant FIV antigen (p24) is used as capture in the kit.
The control line indicates that the test is performed correctly and should appear when the test is complete.
The RIDX^® FeLV Ag/FIV Ab Combo Test Kit can detect FeLV antigens and FIV antibodies in feline blood with high accuracy.

• 10 Tests/Kit

1. All test components and samples must be at room temperature (15~30℃/59~86℉) before use.
2. Take 10μL of blood sample (the anticoagulated whole blood, serum, or plasma) using a capillary tube.
3. Add 10μL of sample into the sample hole (S).
4. Add 2 drops of the sample dilution buffer into the sample hole on the device.
5. Read test result at 10 minutes.
