What is a common requirement for TORCH screening in infants?

A common requirement for TORCH screening in infants is the presence of congenital anomalies. TORCH refers to a group of infections that can cause serious developmental abnormalities in a fetus or newborn. These infections include Toxoplasmosis, Other infections (like syphilis), Rubella, Cytomegalovirus (CMV), and Herpes Simplex Virus (HSV).

When screening for TORCH infections, the presence of congenital anomalies is critical. If a physician or a healthcare provider observes specific anomalies or signs suggestive of TORCH infections—such as microcephaly, cataracts, heart defects, or hearing loss—these findings may prompt further testing for these infections. The screening helps identify which specific infection may be responsible for the observed conditions, allowing for appropriate management and care.

While other factors such as immunization status and maternal vaccination history are important in overall prenatal and perinatal care, they are not direct requirements for conducting TORCH screening in infants. An infant blood sample is also part of the screening process, but this step often follows the identification of anomalies or clinical signs that necessitate further testing.
