General Information
In adults, toxoplasmosis is nearly asymptomatic, requiring no special treatment or prevention. Toxoplasma gondii is pathogenetically significant for immunocompromised individuals, especially those with HIV. It’s classified as a TORCH infection. Primary infection in the first trimester of pregnancy may lead to miscarriage or stillbirth.
IgG antibodies are produced 2-4 weeks post-infection and persist lifelong. The disease has three forms: acute, latent, chronic. Transmission routes:
- Transplacental (mother to child via placenta);
- Consuming raw or undercooked meat;
- Unwashed hands.
It’s not transmitted person-to-person. Result interpretation depends on reference values: negative – below 1 IU/mL, positive – above 3 IU/mL, doubtful – intermediate. Results may be skewed in immunocompromised individuals.
Indications for Toxoplasmosis IgG Testing
Testing is recommended for:
- Pregnancy planning;
- Prevention with chronic hepatitis, encephalitis, myocarditis;
- Unexplained rashes;
- Secondary immunodeficiency with retinal, lung, CNS, or septic involvement;
- Routine newborn screenings.
Antibodies and bacteria form a complex that neutralizes over time. Vaccination is needed if no IgM or IgG antibodies are present in blood serum.
A general practitioner or infectious disease specialist orders the test.
How Is Toxoplasmosis IgG Testing Conducted?
For accurate results:
- Draw blood fasting in the morning;
- Last meal at least 8 hours prior;
- Avoid medications (vitamins, supplements) for 14 days;
- Avoid spicy, fried, fatty foods and smoking 24 hours prior;
- Avoid exertion.
In the lab, rest for 20 minutes. A nurse applies a tourniquet, performs the puncture, and collects the sample, then applies an alcohol-soaked cotton pad.
Completion Time for Toxoplasmosis IgG Testing
Results are ready in 4-6 days.
