Alphabetical Test listing

Cytomegalovirus (CMV) CD8 t-cell immune competence, quantitative assessment by Flow Cytometry-994

Test name:

Test number:

994

Excellian order number:

LAB994

Abbreviation:

MSO

Alternate names:

CMV (Cytomegalovirus)
Cytomegalic inclusion disease (CMID)
Cytomegalovirus (CMV)

Useful for:

Assessing cytomegalovirus (CMV)-specific immune competence in allo-hematopoietic stem cell transplantation patients who are at risk for developing late CMV disease (beyond day 100 after transplant)
Assessing CMV-specific immune competence in solid organ transplant patients who are at high risk for CMV reactivation post-transplant
Monitoring immune competence in patients post-primary CMV infection after transplant who are at risk for CMV reactivation after the cessation of antiviral prophylaxis
Identifying individuals who are likely to be protected from post-transplant CMV infection and those who are at higher risk of CMV reactivation
The global CD8 T cell immune competence assay is useful for determining over immunosuppression within the CD8 T cell compartment, when used on transplant recipients and patients with autoimmune disorders receiving therapy with immunosuppressant agents
