Condition
Herpesvirus causing self-limiting infection in immunocompetent individuals, but with potentially severe consequences in immuno-suppressed transplant patients.
Individual at risk
Recipient
Guidance at RECRUITMENT
ACCEPTABLE
Guidance at CT
ACCEPTABLE
CMV IgG should be performed at CT to ascertain donor CMV serostatus.
Guidance at WORK-UP
CMV-IgG and IgM should be performed at work-up. If CMV IgM is postitive, CMV-PCR should be undertaken.
Testing outcomes and guidance
1
CMV-IgM = negative, CMV-IgG = positive or negative
CMV-IgM = positive, CMV-IgG = positive, CMV-PCR negative
Status information should be reported to the transplant centre
The donor can be cleared at workup.
If there is a change of CMV status from CT to work-up stage, the transplant centre should be informed immediately.
CMV-IgG weak positive results should be referred to reference lab for confirmation
2
CMV-IgM = positive and CMV-IgG = negative and CMV-PCR=negative
Donor can be cleared. Inform TC.
3
CMV-PCR = positive
Donor cannot be cleared. Deferred for 4-6 weeks and repeat CMV PCR then.
Inform transplant centre
Justification for guidance
CMV can cause devastating complications in post-transplant recipients. Accurate donor CMV serostatus plays an important role in donor selection.
