Model Number: TORCH-cassette Brand Name: EGENS Key Specifications/Special Features: IntroductionThe one step cassette style TORCH test is a rapid test based on the principle of immunoassay combined with conjugated colloid gold technology. The test is a diagnostic device for qualitative detection of specific antibody IgM of TORCH in human serum (or plasma) specimen.SUMMARYTORCH is a group of pathogenes including Toxoplasma (TOX), Rubella virus (RV), Cytomegalo-virus (CMV), and herpes simplex virus (HSVⅠand HSVⅡ). TORCH test is one of the prenatal examinations to prevent teratism.Purified recombinant antigens of TORCH pathogenes are precoated onto membrane as a capture reagent on the test band region. If TORCH IgM is present in the sample and concentration above cutoff the labeled anti-human IgM-dye complex will be formed. This complex is then captured by antigens immobilized in the Test Zone of the membrane, producing a visible pink color band on the membrane. The color intensity will depend on the concentration of TORCH IgM present in the sample. This one step test is very sensitive and only takes about 15-20 minutes. Test results are read visually without any instrument.Interpretation of resultsNegative: Only one pink band appears on test region of the Cassette. This indicates that there is no detectable specific IgM in the specimen.Positive: Two pink bands appear on test region of the Cassette. This indicates that the specimen contains detectable amount of specific IgM.Invalid: If without colored band appears on test region, this is an indication of a possible error in performing the test. The test should be repeated using a new device.
