TORCH Framework

TORCH Screening Framework

Indications & Diagnostic Rationales

T

Toxoplasmosis

O

Other (Syphilis)

R

Rubella

C

CMV

H

HSV

Diagnostic Triggers

Maternal Exposure

Known contact with primary infection (especially Rubella/VZV).

Ultrasound Markers

Intracranial calcifications, Hydrops, Organomegaly, Microcephaly.

Seroconversion

Rising IgG or presence of IgM with low Avidity.

Fetal Growth

Severe early-onset Fetal Growth Restriction (<20 weeks).

Clinical Ref: Routine "Panel" testing is discouraged by FIGO/RCOG due to high false-positive rates. Testing should be serial and pathogen-specific based on clinical suspicion.

Guidelines & Evidence

Verified

Last Review: 2026

When to Use

When to Use

Differential diagnosis for symmetric Intrauterine Growth Restriction (IUGR).
Evaluation of fetal anomalies on ultrasound (e.g., intracranial calcifications, microcephaly, hydrops).
Screening pregnant patients with concerning exposures or viral prodromes (fever, lymphadenopathy, rash).
Workup for unexplained stillbirth or neonatal jaundice/thrombocytopenia.

Exclusion Criteria

The TORCH framework is a screening heuristic. It is not a single "test" but a diagnostic approach. Routine universal TORCH screening in asymptomatic patients is not cost-effective and is generally discouraged by ACOG.
