Evaluation of Novel Tools to Facilitate the Detection and Characterization of Leprosy Patients in China
Antigen recall responses of leprosy patients. Venous heparinized whole blood from PB, MB, HHC, TB, and EC was incubated with various antigens for 24 hours; then plasma was collected, and IFN content was measured by ELISA. Results from each individual WBA are distinguished by an individual marker. The dashed horizontal line represents the cutoff (50 pg/mL) for positive results.
