TORCH IgM and TORCH IgG Rapid Test Kits

TORCH test Panel and single casette

One step TORCH rapid test panel is a rapid qualitative screening test device, which are intended to be used in the field as the eugenics test kits. TORCH IgG test and TORCH IgM test are lateral flow testing panels, designed for the respective qualitative detection of IgG and IgM antibodies to a group of viruses which can affect the health development of fetus, namely Toxoplasma gondii (Toxoplasmosis, TOXO), Cytomegalovirus (CMV), Rubella Virus (RV), Herpes Simplex virus I (HSV-1) and Herpes Simplex virus II (HSV-2) respectively. IVD TORCH test kits are used as a screen devices for the health condition of fetuses. We are supply both TORCH IgM test and TORCH IgG test.

Single rapid test cassettes are available for all the five virus infections; and single Dot Filtration assay Kits and ELISA kits are also available for all these viruses. For specific information about single parameter, please refer to the specific pages of TOXO Test kits, CMV Test kits, RuV Test kits, HSV-1 Test kits and HSV-2 Test kits respectively.

Testing Principle of TORCH Rapid Test Kits

Both TORCH IgM screening test and TORCH IgG screening test are Gold Immuno-chromatography Assay (GICA), based on sandwich immunoassay principle. Recombinant antigens of the five viruses and anti-human IgM or IgG antibodies to the five viruses are respectively used to detect the specific antibodies in human serum or plasma samples. When the samples are added to the sample wells on the test panel, the antibodies, if present in the specimen, will react with the anti-human IgM antibody in the membrane strip, and immuno complexes will emerge. These complexes move along the membrane strip chromatographically to the test region (T), where the immuno complexes will be captured by the pre-coated recombinant antigen. Then a red or pink line will appear, indicating a positive result for the specific antibody to the virus.

TORCH test Panel

The unbounded complex moves on to the control region (C), where they are captured by the anti-mouse antibody, and a red line will appear, indicating the assay is valid. In this way, the control line provides an inner quality control mechanism. The color intensity is in accordance with the concentration of the respective antibody to the related TORCH virus in the samples.

About the TORCH Viruses

The acronym TORCH was introduced in 1971 to highlight a group of viral diseases which affect the fetus and newborn, namely Toxoplasma gondii (TOXO), rubella virus (RV), cytomegalovirus (CMV), and herpes simplex viruses (HSV). These diseases often lead to a similar clinical picture which includes one or more of the following clinical signs: low birth weight, prematurity, purpura, jaundice, anemia, microcephaly, hydrocephaly, cerebral calcification, chorioretinitis, cataracts, microphthalmia, hearing impairment, mental retardation, autism and pneumonitis.

The early diagnosis of ToRCH infection is very important to avoid the symptoms and lesions. For example, toxoplasmosis can be effectively treated with antibiotics if the mother is diagnosed early in her pregnancy. If the mother has active herpes simplex, delivery by Caesarean section can prevent the newborn from contact, and consequent infection, with this virus. As an aid in the screening of ToRCH infection, TORCH IgG test and ToRCH IgM test are now widely requested by clinicians investigating infants and pregnant women for congenital, perinatal and neonatal infections. With infants, when physical examination of the newborn shows signs of the TORCH syndrome, doctors may test blood, urine, and spinal fluid for evidence of the ToRCH infections listed above. Diagnosis can be confirmed by culture of one of the specific pathogens or by increased levels of IgM against the pathogen.

TORCH screening is now widely requested by clinicians investigating infants and pregnant women for congenital, perinatal and neonatal infections.
