Screening kit and method for diagnosing chronic immune dysfunction syndrome

摘要

The subject invention permits diagnosis of chronic fatigue syndrome (CFS) by analyzing peripheral blood mononuclear cell subset populations and activation markers. A positive diagnosis for CFS is associated with an increase in the percentage of CD8+ cells showing CD38 or HLA-DR cell markers or a decrease in CD11b markers in CD8+ cells. The analysis is preferably performed using fluorochrome-labelled monoclonal antibodies specific for a determinant of the above subset cells and activation markers.
