Toxoplasma Gondi Infection Test

The FDA has approved a test to help determine whether a patient has a recent Toxoplasma gondi infection. The VIDAS TOXO IgG Avidity assay is a meaningful weapon in helping doctors rule out an infection within the last four months.

This is welcome news for everyone but particularly pregnant woman who if infected with Toxoplasma may pass it on to their child which can cause a host of serious and potentially fatal consequences not just in vitro but later in the child’s life.

“Toxoplasmosis can have serious and lasting health consequences for infants that acquire the infection in the womb,” said Alberto Gutierrez, an FDA official in the Office of In Vitro Diagnostic Device Evaluation and Safety. “This test gives doctors an additional tool to determine if women with confirmed cases of toxoplasmosis acquired the infection before or during pregnancy.”

This test is not going to be the only test for this infection and the FDA said it has not cleared or approved the assay for blood or plasma donor screening. But it sounds like progress in keeping our most vulnerable safe.
