Del - the PCR is the 3rd FeLV test (altho PCR is used for many other diseases esp. early detection of HIV). Anyway, it is Polymerase Chain Reaction, which detects viral nucleic acid sequences in a cell.. basically it looks for the DNA of the FeLV virus. It can be used to satisfy discordant results or to detect FeLV that is restricted to a particular tissue (such as bone marrow). It will also detect a latent FeLV virus - both ELISA and IFA will not detect a latent virus. A latent infection usually follows transient infection for 4 to 9 months but proviral DNA remains in lymphoid or marrow tissue. The PCR will detect this.
