Toxoplasma Avidity, IgG

The Toxoplasma Avidity, IgG test is the standard blood test that checks for toxoplasma-specific antibodies in the blood. For pregnant women, the doctor will take a sample of the amniotic fluid and the fetus's blood. The doctor then studies the samples to determine if the infection has been transmitted to the fetus.

Toxoplasmosis is an ailment caused by Toxoplasma gondii, one of the most commonly encountered parasites in the world. The disease usually spreads by either eating undercooked meat, exposure to infected faeces of cats, or genetics, where it passed from the mother to the child during pregnancy. 

This test is primarily responsible for measuring the antibody binding force, which differs depending on the time of the infection. The antibody binding force is low in the initial stages of the infection; while a high value suggests that the infection had likely occurred around 4 months ago. IgG antibodies appear a few weeks after the toxoplasmosis infection and may remain in the body forever. But the blood test can detect these antibodies almost instantly.

Although the toxoplasmosis infection is mainly asymptomatic, the few visible symptoms associated with it are similar to that of flu, and may include body aches, swollen lymph nodes, fever, headache, and fatigue. Those with weakened immune systems may experience lung problems that resemble tuberculosis, fits (seizures), poor coordination, confusion, retinal inflammation causing blurred vision, or constant headache. Children might also contract a toxoplasmosis infection from their mothers and may show symptoms like severe eye infections and yellowing of the skin.
