Toxoplasma IgG

The Toxoplasma IgG test is a blood test used to detect IgG antibodies produced in response to infection by Toxoplasma gondii, a parasite that can cause toxoplasmosis.

IgG antibodies usually appear after the initial infection and remain in the body for life, indicating past exposure or immunity. This test is especially important in pregnant women and immunocompromised individuals, as toxoplasmosis can lead to serious complications.

The test measures IgG antibodies in the blood.

• A positive result typically indicates past infection and immunity
• A negative result suggests no prior exposure

It is often used alongside Toxoplasma IgM testing to determine whether an infection is recent or past.

The purpose of this test is to:

• Detect IgG antibodies against Toxoplasma gondii
• Determine past infection or immunity
• Assess risk during pregnancy
• Support diagnosis of toxoplasmosis
