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:
Code | Test Name | Can it be requested separately? | Is it always done? |
---|---|---|---|
0168 | Cytomegalovirus, DNA | Yes | No (*) |
* Only performed upon request and requires a whole blood sample.
Response Time:
Maximum of 2 working days.
Specimen information
Sample: Serum and/or plasma
Tube: Aliquots of 1-5 mL, plasma tubes with EDTA, sodium citrate, heparin, ACD, CPDA-1, or CPD as anticoagulant and/or serum tubes with or without gel separator.
Minimum essential volume: 1 ml
Stability:
- At room temperature: ≤ 3 days
- In refrigeration at 2-8 ºC: ≤ 14 days
- Frozen sample equal to or less than -20ºC: 10 years
Transport instructions: Preferably at room temperature if they are whole blood tubes and refrigerated if they are serum and/or plasma aliquots.
Reason for rejection: Highly hemolyzed sample.
