Quality of FeLV & FIV Tests

Hartmann, K., P. Griessmayr, et al. (2007). “Quality of different in-clinic test systems for feline immunodeficiency virus and feline leukaemia virus infection.” J Feline Med Surg 9(6): 439-45.

There are many commerical kits available for in-clinic diagnosis of feline leukemia virus (FeLV) and feline immunodeficiency virus (FIV). This study evaluated seven FIV and eight FeLV test kits. The researchers tested 536 serum samples from randomly selected cats. Positive FIV tests were confirmed with Western blot and positive FeLV tests were confirmed by virus isolation. Specificity, sensitivity, positive and negative predictive values of eact test were determined. All test kits performed well, with the exception of one kit that produced unacceptable numbers of invalid test results and results that are difficult to interpret. Positive test results should always be confirmed, especially in a healthy cat from a low-risk environment.
