Cytomegalovirus (CMV) IgG EIA
A special account is required to order pre-transplant testing. Contact Client Services or your account executive to set up a pre-transplant account to order this assay. Specimens should not be collected until after account has been created.
For the detection of human IgG antibodies to cytomegalovirus in human serum by enzyme immunoassay, as an aid in the determination of acute or reactivated infection with CMV. When used as a qualitative test, CMV IgG EIA aids in the assessment of the patient's immunological response to CMV. These reagents have not received FDA clearance for use in testing blood or plasma donors.
Cytomegalovirus (CMV) is the causative agent of cytomegalic inclusion disease, a generalized infection of infants caused by intrauterine or early post natal infection. The disease may cause sever congenital abnormalities, such as microcephaly, motor disability, and mental retardation in infants.1-3 Cytomegalovirus infection has also been associated with acquired hemolytic anemia, acute and chronic hepatitis, and an infectious mononucleosis-like syndrome. Subclinical infection may occur in adults.4 CMV infection can be transmitted to immunodeficient or immunocompromised individuals, as a result of blood transfusion5 or organ transplantation.6
Serological tests, such as the CMV IgG EIA test, which detect the presence of CMV IgG antibodies, can aid in the diagnosis of diseases caused by cytomegalovirus. Test results are obtained after one and one-half hours incubation time. They are objective and normalized as index values, permitting uniformity or reporting.
Diluted samples are incubated in antigen-coated wells. Absorbents have been included in the Diluent to neutralize the effects of rheumatoid factor and anti-CMV IgG antibody. CMV antibodies (if present) are immobilized I the wells. Residual sample is eliminated by washing and raining, and conjugate (enzyme-labeled antibodies to human IgM) is added and incubated. If IgM antibodies to CMV are present, the conjugate will be immobilized in the wells. Residual conjugate is eliminated by washing and draining, and the enzyme-labeled substrate is added and incubated. In the presence of the enzyme, the substrate is converted to a yellow end product which is read photometrically.
