ABSTRACT: Immuno screening was carried out by ELISA for the samples from the patients admitted in Kastruba Hospital, Sevagram. Blood samples of patients of pulmonary and extra pulmonary tuberculosis were examined for presence of tuberculosis specific antibody, antigen and combine sensitivity was also tested. Antigen preparation namely M.tbH37Ra ES-31 and 41 were used for the detection of tubercular IgG antibody whereas affinity purified anti ES-31 antibody was used for tubercular circulating free and immune complexed (CIC) antigen. ES-31 showed more sensitivity in pulmonary, lymphnode, CNS, genito uninary TB and ES-41 showed more in abdominal, osteo articular TB, percentage positivity in combined Ab/ Ag/ CIC-Ag sensitivity was found more.
