Test Code TGPQC Toxoplasma gondii Quantitative Real-time PCR (CSF)

Clinical Indications

Toxoplasma gondii is highly problematic when primary infection
occurs during the first trimester of pregnancy, often leading to
fetal death or when reactivation occurs in immunocompromised
patients, leading to life-threatening disease including
encephalitis and extracerebral toxoplasmosis. Onset of disease in
most patients is preceded by an increase in parasite load.
Monitoring blood levels of Toxoplasma gondii DNA correlates well with treatment.
