===Laboratory Tests===
The diagnosis is usually based on blood tests that detect antibodies against the parasite. However, if the person's immune system is impaired by AIDS, the blood test may be falsely negative. To determine whether a fetus has been infected, a doctor usually takes a sample of the fluid around the fetus (amniotic fluid) to be analyzed.
===Diagnostic Imaging===
If toxoplasmosis of the brain is suspected, computed tomography (CT) or magnetic resonance imaging (MRI) of the brain is done. Less commonly, a piece of infected tissue is removed and examined under a microscope (biopsy) to identify parasites or characteristic proteins (antigens) released by the parasite.
