Useful For Suggests clinical disorders or settings where the test may be helpful

Determining the presence of naive, memory, and activated T cells in various clinical contexts including autoimmune diseases, immunodeficiency states, T-cell recovery post-hematopoietic stem cell transplant, DiGeorge syndrome, and as a measure for T-cell immune competence

 

Naive T-cells results can be used as a surrogate marker for thymic-derived T-cell reconstitution, when used in conjunction with assessment of T-cell receptor excision circles (TREC / T-Cell Receptor Excision Circles [TREC] Analysis, Blood)

 

Assessing a patient's relative risk for infections

 

Evaluation of patients with cellular or combined primary immunodeficiencies

 

Evaluation of T-cell reconstitution after hematopoietic stem cell transplant, chemotherapy, biological therapy, immunosuppression, or immunomodulator therapy

 

Evaluation of patients with autoimmune diseases

 

Evaluation of HIV-positive patients for naive and memory subsets

 

Evaluation of T-cell immune competence (presence of memory and activated T cells) in patients with recurrent infections
