Cytomegalovirus, IgG Antibodies. Screening

Clinical information

Diagnostic Utility:

This is the qualitative detection of IgG antibodies against cytomegalovirus (CMV) and its determination is useful in:

• Identification of seronegative individuals, as well as seronegative donors of organs, blood products, semen, or ova.
• Transfusion of blood products in newborns, pregnant women, patients with liver disease, and immunosuppressed patients.
• Transplantation of progenitor cells, umbilical cord blood, solid organs.

Method:

Chemiluminescence microparticle immunoassay (CMIA).

Reference Values

Possible results are: Reactive and Non-Reactive.

Diagnostic Algorithm:

In the case of a reactive result for CMV anti-IgG and/or CMV anti-IgM, the CMV DNA detection test can be requested upon request:

* Only performed upon request and requires a whole blood sample.

Response Time:

Maximum of 2 working days.
