Diagnostic method for chronic fatigue syndrome by measuring elastase

摘要

The present invention relates to methods and kits for the diagnosis and confirmation of Chronic Fatigue Syndrome (CFS) by measuring elastase activity in a patient sample, preferably a PBMC sample. The assays of the invention can also be used to characterize CFS, to determine the disease stage, the disease progression, the efficiency of a therapeutic regime and/or to predict the recurrence of possible attacks. The assays of the invention advantageously allow CFS to be distinguished from other CICIDs like MS or RA.
