Which type of antibody does the SNAP 4Dx Test detect?
The A. phagocytophilum portion of the SNAP 4Dx Test detects both IgM and IgG antibodies. As with most infections, the immune system will produce high concentrations of IgM antibodies during the early acute phase of infection. Later in the course of infection, the immune system will begin to produce IgG antibodies, which can remain elevated in the serum for months to even years.
