background
The determination of a primary infection may be easy if the patient’s serological history is known, or more complex in the case of a first positive sample during pregnancy. In this case, several indicators, all imperfect, can be used: the presence of IgM, the avidity of IgG, the presence of IgA (Olariu et al., 2019), the evolution of the antibody titer (Montoya et al.,2008). The presence of IgM, as most commonly detected by ELISA, is theoretically a marker of primary infection but lacks specificity (Villard et al., 2016a) and residual IgM is detected in a significant number of cases: 1 year after infection between 9 and 27% of patients may still have detectable IgM (Villard et al., 2016b). Avidity of IgG also allows a dating and excludes a recent infection in case of high avidity. However, some patients never develop high avidity so a low avidity does not indicate a recent infection. Finally, a significant increase in IgG levels between 2 samples two weeks apart is in favor of a recent infection. Conversely, stable IgG levels indicate an infection older than 3 months (Villard et al., 2016b).
