Properties
Background Toxoplasma gondii shows the highest incidence of any human pathogenic parasite in central Europe. As a rule, the course of the infection is asymptomatic or mild and confers lifelong immunity on immunocompetent persons. Initial contact with the pathogen during pregnancy can result of transmission of the pathogens to the foetus, resulting in severe damage to it.The main task of routine diagnostics is therefore a preventive testing before or during pregnancy. Due to the frequently subclinical course and the mostly uncharacteristic clinical picture, a clinical diagnosis is impossible without laboratory tests and is mainly based on serological methods with its main interest to differentiate acute infections from past infections. It is well known that Toxoplasma specific IgM antibodies can persist for month or even years after initial contact, so a positive IgM finding is not sufficient for the diagnosis of an acute toxoplasmosis. Much more of importance is to determine the avidity of Toxoplasma specific IgG antibodies.The recomLine Toxoplasma is worldwide the only test system which meets the requirements for the special diagnosis of toxoplasmosis especially for pregnancy. The optimized combination of using recombinant antigens for IgG and IgM and also 4 different phase specific avidity antigens is unique on the market for the determination of the status of a Toxoplasma infection.

Description Test principle and procedure.

1. 1st Incubation. One (two*) strip loaded with Toxoplasma antigens is incubated with diluted serum or plasma in a dish for 1 hour.
2. Wash 3 (1*) times
3. Avidity step* (IgG only - does not apply to normal processing). Wash buffer is added to one strip and the dissolved avidity reagent is added to the other strip, followed by a 3 minute incubation. Low avidity antibodies will be “washed off” by the avidity reagent.
4. Wash 3 times
5. 2nd Incubation
6. Peroxidase conjugated anti-human antibodies (IgG, IgM or IgA specific) (IgG specific only*) are added. Incubate for 45 minutes.
7. Wash 3 times
8. Color reaction. 8 minutes after addition of the coloring solution, insoluble colored bands develop at the sites on the test strips occupied by antibodies. (By direct comparison of the intensity of the corresponding bands on the two strips, the avidity of individual anti-Toxoplasma IgG antibodies can be determined.*)
