TORCH is an acronym for several infections that are included in the screening of infectious diseases that could affect the evolution of pregnancy and the conception product:

• Toxoplasmosis
• Other (other) diseases: HIV, syphilis, chickenpox etc.
• Rubella
• Cytomegalovirus
• Herpes Simplex Virus

Preconceptional serological evaluation is useful for the knowledge of the immunologic status of each patient related to these infections, whether were previously exposed to the infectious factor and whether are susceptible to the disease in the course of the future pregnancy. The usefulness of this evaluation is especially great in the case of diseases for which vaccination is possible (rubella, chickenpox), this prophylactic measure being indicated in all cases where the immunity to the virus is not detected. The best way to protect the unborn child is even maternal protection. In addition, if the presence of an acute infection is identified at the time of testing, it is advisable to postpone the conception after healing. In the case of uteroplacental barrier crossing, foetal damage generally includes cataracts, deafness, intellectual disabilities, heart diseases, convulsions, retardation, etc., most of the changes not being accurately documented by the ultrasound examination.

Preconceptional testing and knowledge of the immunologic status of pregnant women from the beginning of pregnancy also allows for establishing behavior in case of contact with one of these conditions during pregnancy.

TORCH testing is extremely simple, without requiring any special training, similar to any collection of a blood sample from the peripheral blood. The existence of IgM antibodies signifies an acute infection at the date of testing and the patient will be guided to a specialist doctor. The existence of IgG antibodies signifies the previous contact with the infectious agent against which the body has developed immunity.
