TORCH UPDATED ACTUAL QUESTIONS AND CORRECT ANSWERS
What does the TORCH panel evaluate? Congenital infections: Toxoplasmosis, Other (Syphilis, Varicella), Rubella,
Cytomegalovirus, and Herpes Simplex Virus.
What are the key learning outcomes for infectious Characteristics of acquisition, development, innate body defenses, and
disease acquisition? comparison of immunologic manifestations of acquired vs. congenital infections.
What is the significance of IgG in the TORCH panel? Indicates past infection/immunity or passive maternal transfer.
What does a positive IgM indicate in the TORCH panel? Recent infection; crucial for diseases with indistinct symptoms.
What is the primary etiologic agent of Toxoplasmosis? Toxoplasma gondii.
How is Toxoplasmosis primarily transmitted? Foodborne (undercooked meat, contaminated water/produce), zoonotic
(cleaning cat litter), and transplacental (acute maternal infection).
What are the clinical manifestations of congenital Microcephaly, hydrocephalus, intracranial calcifications, and sequelae like
Toxoplasmosis? chorioretinitis and blindness.
What does a high avidity IgG indicate? Past infection (>5 months) and lower risk of recent infection.
What is the historical 'gold standard' test for Sabin-Feldman Dye Test.
