TORCH and Special ID AssaysSiemens Healthineers provides TORCH and special infectious-disease assays for improved prenatal and specialty care.

TORCH
TORCH is an acronym for a group of infectious organisms, which in healthy individuals can lead to treatable and mild disease, but when acquired during pregnancy can cause significant birth defects and even fetal death. Therefore, recognizing maternal disease and monitoring the patient when diagnosed are important for clinicians treating patients. Understanding this group of illnesses can help clinicians counsel patients to prevent infection and address fetal outcomes if infected.

TORCH is comprised of the following:

Toxoplasma
Other (HIV)
Rubella
Cytomegalovirus (CMV)
Herpes simplex virus (HSV)

Special Infectious Disease
Siemens Healthineers offers special infectious-disease (ID) assays* to help laboratories address critical and common infectious diseases and help clinicians make critical decisions. Siemens Healthineers offers the following special ID tests as part of a growing menu:

Epstein-Barr Virus (EBV) VCA IgG
Epstein-Barr Virus (EBV) VCA IgM
Epstein-Barr Virus (EBV) EBNA IgG
H. pylori IgG
Syphilis
Zika Virus

Siemens Healthineers offers TORCH and special ID testing assays for the Atellica® IM Analyzer, ADVIA Centaur® Immunoassay Systems and IMMULITE® Immunoassay Systems.

Understanding this group of illnesses can help clinician’s counsel their patients to help prevent infection, and address fetal outcomes if infected. Patient history and risk factors guide prenatal and maternal testing for TORCH. These tests are often performed in the first trimester of pregnancy.
