Toxoplasmosis is an infection caused by the toxoplasma parasite. Infection usually occurs through eating undercooked, contaminated meat or cleaning a cat’s litter box when the cat has shed Toxoplasma in its faeces. Often those who are infected have very few symptoms because a healthy person’s immune system usually keeps the parasite from causing illness. However, those with compromised immune systems and pregnant women should be cautious as an infection can cause serious health problems and affect the unborn child.
The body produces Toxoplasma IgG antibodies after being infected by this parasite.
What might a high result mean?
A positive toxoplasma IgG antibody result indicates you have had a past infection. A IgG result alone cannot confirm or deny a current infection.
