Toxoplasmosis Testing and Results

Spread the love

Toxoplasmosis testing is to detect a Toxoplasma gondii infection in a pregnant woman, unborn baby, or in a person with a weakened immune system. Toxoplasmosis is an infection caused by the parasite Toxoplasma gondii (T. gondii).

What does the test result mean?

Antibody detection
  • Negative IgM and positive IgG: past infection.
  • Negative IgM and negative IgG: infection or very early infection or no previous exposure.
  • Positive IgM and negative IgG: early infection; in a newborn, indicates congenital infection.
  • Positive IgM and positive IgG: current infection; chronic infection; could indicate re-activation; IgM may be positive for several months after the infection resolves.
DNA detection

If the molecular test is positive for T. gondii DNA, then the person tested has an active toxoplasmosis infection.

A negative test result means that it is less likely that the person has toxoplasmosis but does not rule out infection.
