ELISA-type tests detect the presence of free FeLV particles that are commonly found in the bloodstream during both the early and late stages of infection. The indirect immunofluorescent antibody assay (IFA) test is usually sent out to a diagnostic laboratory after a positive ELISA test to confirm FeLV infection.

The FeLV Antigen by ELISA with FeLV Quant RealPCR Test, test code 26355 (or add-on test code 263551 when ordered with a CBC/chemistry profile), is recommended as a confirmatory and staging test following an in-clinic screening FeLV antigen test.

ELISA (enzyme-linked immunosorbent assay) and similar tests can be performed in your veterinarian's office. ELISA-type tests detect both primary and secondary stages of viremia.

The FeLV-ELISA test on blood detects small quantities of soluble antigen in serum; the IFA tests for antigen in leukocytes. The ELISA is more sensitive and can detect antigen in the early viremic and incubation periods when only lymphocytes are infected.

Testing your cat for leukemia using the enzyme linked immunosorbent assay (ELISA) test is beneficial, as you can start supportive care as soon as possible. Offering medical help in a timely manner to a cat with leukemia can prolong the pet's life, and give him a quality time.

For any cat used as a blood donor or for breeding, consider also screening with FeLV RealPCRTM Test *If less than 30 days since last possible exposure, retest in 30–60 days.

Today, FeLV infection is usually diagnosed by the detection of the FeLV core protein p27 in the peripheral blood by double-sandwich antibody ELISA 10 or by Immunochromatography. 6 In ELISA, presence of antigen leads to binding of an enzyme-conjugated antibody and after the addition of a substrate, to colour formation in the ELISA well or on the ...

2024年12月20日 · Remaining negative in enzyme-linked immunosorbent assays (ELISA) due to the absence of circulating viral proteins. Despite the lack of active infection, regressive infection is associated with a reduced life expectancy due to the potential development of FeLV-related diseases. Several factors can influence FeLV transmission. These include:

Clinicopathologic criteria were used to group 68 cats according to high, moderate, or low suspicion of having feline leukemia virus (FeLV)-related disease. Peripheral blood samples were tested for FeLV antigen by enzyme-linked immunosorbent assay (ELISA) and for FeLV DNA by polymerase chain reaction …

Positive results of a point-of-care (POC) ELISA for FeLV indicates the presence of viral antigen (p27. Confirmatory testing is ideal and should include FeLV quantitative real-time PCR assay. …
