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.
When the body is exposed to the toxoplasma parasite, the immune system responds by producing antibodies to the parasite. IgM antibodies are the first to be produced by the body in response to a Toxoplasma infection.
What might a high result mean?
A positive toxoplasma IgM antibody result indicates you have had a recent or current infection.
