The Toxoplasma IgG Avidity (AviDx) test is capable of differentiating primary toxoplasmosis from past infection in pregnant women. A fetus contracting primary toxoplasmosis from the mother can sustain chorioretinitis or neurologic defects, so it is important to test for it if the woman has clinical or serologic evidence of toxoplasmosis.
The infection is caused by Toxoplasma gondii, a microbe that can be contracted from cats. Also provided is an educational pamphlet for healthcare workers, “Clinical Perspectives in Laboratory Diagnostics.”
