Test Parameters & Specifications
Sample Stability
- Hemolyzed or clotted samples
- Insufficient sample volume
- Improperly labeled or contaminated specimens
Understanding Your Results
IgG Positive, Avidity <30%
Likely current or recent infection; consult doctor for further management
IgG Positive, Avidity ≥30%
Past infection with established immunity; generally low risk
IgG Negative
No detectable immunity; consider retest if exposure suspected and monitor symptoms
Consult a healthcare provider if you have symptoms of toxoplasmosis, are pregnant, immunocompromised, or if test results indicate active infection for appropriate treatment and monitoring.
Limitations
- ⚠Cannot distinguish between active and past infection without avidity testing
- ⚠Negative result does not rule out very early infection; repeat testing may be needed
- ⚠Not suitable for diagnosing acute toxoplasmosis in isolation; clinical correlation is required
Risks & Considerations
- ●Minor pain or bruising at the blood draw site
- ●Very rare risk of infection or hematoma
- ●No significant risks associated with the test itself
Interfering Factors
- ●Hemolyzed or lipemic samples may affect accuracy
- ●Recent blood transfusions could interfere with antibody detection
- ●Cross-reactivity with other parasitic infections is possible but rare
