The ELISA-VIDITEST anti-HHV-6 IgG kit is intended for the serological diagnosis of diseases associated with HHV–6 infection, such as exanthema subitum, acute respiratory illnesses, diarrhea with fever and febrile seizures in infants, heterophile antibody-negative infectious mononucleosis in children, and interstitial pneumonia, encephalitis, meningitis, hepatitis and aplastic anemia in immunodeficient patients. The presence of IgG anti-HHV-6 antibody reveals the immune status of the patient. A significant rise in anti-HHV-6 IgG antibodies in paired serum samples, taken in the acute and convalescent phase of the infection, is indicative of the active infection.
This kit can be used for the anti HHV-6 antibody determination in human sera or cerebrospinal fluids (CSFs). Using quantitative evaluation, the tests can be applied for intrathecal antibody synthesis assessment. The kit does not differentiate between HHV-6 subtype A and B. The assays should be supplemented with determination of anti-HHV-6 IgM antibody in human serum. We recommend the anti-HHV-6 IgM ELISA kit.
The anti-HHV-6 IgG assay is a solid-phase immunoanalytical test that detects IgG antibodies to HHV-6. The strips are coated with native HHV6 antigen. If present in the sera tested, anti-HHV-6 antibodies bind to the immobilized antigens. The antibodies in complexes with antigens are later recognized by animal anti-human IgG antibodies labeled with horseradish peroxidase. The attached labeled antibodies are revealed by an enzymatic reaction with a chromogenic substrate. Negative sera do not react. A mild change in color, if present, may be attributed to the reaction background.
