EIAs are relatively fast, taking on average about 2 hours total per batch, and allow for the screening of vast numbers of patients in a short period of time. Along with this, new syphilis EIA tests use a cocktail of recombinant antigens to detect T. pallidum specific IgG, IgM, and IgA antibodies in serum or plasma samples. This makes the assay an effective diagnostic in all stages of infection except those that are very early primary syphilis. It should be kept in mind that the EIA and ICS assays are still treponemal tests and will likely remain positive for the lifespan of those who have had syphilis, even with adequate treatment.

Hence, the 14 day window for testing.....
Glad I could help.
