Abstract

Abstract: Objective To evaluate of Tb NT P BSA antigen in the diagnosis of tuberculosis.Method Sera from 40 tuberculosis cases and 52 healthy controls were assayed by ELISA using Tb NT P BSA(containing the terminal triglycosyl unit of the M.tuberculosis phenolic glycolipid) as antigen.Results The sensitivity and specificity were 94.2%,20.0% for IgG and 79.6%,45.0% for IgM antibody activity respectively.Conclusion This antigen is not sensitive,that will limit its use in the serodiagnosis of tuberculosis.

Key words: Tb NT P BSA, Serodiagnosis, Tuberculosis
