Table 1.
Serological parameters of 717 samples categorised in six groups and subgroups according to the toxoplasmosis status.
Table 2.
Percentage of low IgG avidity results in the first sample in three categories of patients with recent acute toxoplasmosis and with past toxoplasmosis.
Table 3.
Percentage of low anti-Toxoplasma IgG avidity in 694 samples categorised by IgG concentration.
Table 4.
Diagnostic parameters of low IgG avidity (regardless of other tests) upon confirmation or exclusion of acute toxoplasmosis.
Fig 1.
Kinetics of the avidity index (AI) in individual patients followed-up with 2–6 samples, starting with low (AIF0A30.3—green) or high (AI>0.3—blue) IgG avidity in the course of toxoplasmosis.
The trend lines obtained from the regression model are marked in purple for patients with low avidity, and in red for patients with initial high avidity. Graphs (A) and (B) represent pregnant women, graphs (C) and (D) non-pregnant women, while graph (E) includes congenitally infected newborns and (F) seropositive uninfected newborns and infants up to six months of age. Graphs (A) and (C) are related to the recent acute toxoplasmosis, graphs (B) and (D) to the past toxoplasmosis. The low avidity threshold of 0.3 is indicated by the dashed orange line.
