Regarding feline leukemia testing in kittens: What is it

Customer Question

Regarding feline leukemia testing in kittens: What is it about the mother's antibodies that can sometimes result in false negative test results in kittens under 12 weeks of age? And, which tests are the most likely to be influenced by maternal antibodies?

Actually, kittens can be tested at any age because passively acquired maternal antibody DOESN'T interfere with testing for viral antigen such is done with the FeLV ELISA in-house testing. You may be referring to testing for kitty AIDS (FIV) in which maternal antibodies do confound test results. If FIV positive and less than 6 months of age, retesting at intervals of 30 days until the kitten tests negative or is greater than or equal to 6 months of age is indicated.
