How does the SNAP 4Dx A. phagocytophilum test differ from a PCR test?
• A PCR test works by identifying and then amplifying the actual organism’s DNA or RNA when found in the blood. If performed correctly under proper laboratory conditions, PCR tests are highly specific, but can be less sensitive than antibody detection tests. • The SNAP 4Dx Test is an ELISA assay that identifies the presence of antibodies to A. phagocytophilum. As with any antibody test, the organism may have been eliminated, yet the antibody levels remain high enough to be detected by the SNAP 4Dx Test. A. phagocytophilum may be eliminated from the dog by self-resolution or with antibiotics.
