Diagnosis
A thorough history, physical examination, and laboratory testing will be needed to rule out other possible diseases that could cause similar symptoms. Blood tests can show anemia, low white blood cell count and liver enzyme elevations. Blood serology tests can give information about exposure to toxoplasmosis; however, these tests must be performed repeatedly to determine if infection is active or chronic. Other diagnostics that may be recommended include x-rays, cerebrospinal fluid analysis, and cytology, which analyzes fluid or tissue cells. Special fecal tests can detect the infective oocysts, although they are rarely shed when clinical disease is present.
