Diagnosis of active tuberculosis in China using an in-house gamma interferon enzyme-linked immunospot assay.
Gamma interferon (IFN-gamma) release assays have been proven to be useful in the diagnosis of Mycobacterium tuberculosis infection. Nevertheless, their specificity and sensitivity vary among the different populations studied. Here, we evaluate the value of an in-house IFN-gamma enzyme-linked immunospot (ELISPOT) assay in the diagnosis of active tuberculosis (TB) in Shenzhen, China, where the pr...
متن کاملUse of Pleural Fluid Interferon-gamma Enzyme-linked Immunospot Assay in the Diagnosis of Pleural Tuberculosis.
AIM to evaluate the diagnostic value of an interferon-gamma release assay (IGRA) with enzyme-linked immunospot (ELISPOT) method, T-SPOT.TB, in the diagnosis of pleural TB using pleural fluid mononuclear cells (PFMC). METHODS forty-eight subjects, presumed to have pleural TB with exudative pleural effusion by Light's criteria, dominated by mononuclear cells, had their pleural fluid specimen te...
متن کاملSelected RD1 peptides for active tuberculosis diagnosis: comparison of a gamma interferon whole-blood enzyme-linked immunosorbent assay and an enzyme-linked immunospot assay.
We recently set up a gamma interferon (IFN-gamma) enzyme-linked immunospot assay (ELISPOT), using selected early secreted antigenic target 6 (ESAT-6) peptides, that appears specific for active tuberculosis (A-TB). However, ELISPOT is difficult to automate. Thus, the objective of this study was to determine if the same selected peptides may be used in a technique more suitable for routine work i...
متن کاملDiagnosis of Tuberculosis by an Enzyme-Linked Immunospot Assay for Interferon-γ
We evaluated an enzyme-linked immunospot assay for interferon-gamma (T SPOT-TB) for rapid diagnosis of active tuberculosis (TB) in a disease-endemic area. From January to June 2005, patients whose clinical symptoms and radiographic findings were compatible with TB were recruited, and a blood sample was obtained for T SPOT-TB assay within 7 days of microbiologic studies. Sixty-five patients were...
متن کاملAn in-house RD1-based enzyme-linked immunospot-gamma interferon assay instead of the tuberculin skin test for diagnosis of latent Mycobacterium tuberculosis infection.
Identification of individuals infected with Mycobacterium tuberculosis is essential for the control of tuberculosis (TB). The specificity of the currently used tuberculin skin test (TST) is poor because of the broad antigenic cross-reactivity of purified protein derivative (PPD) with BCG vaccine strains and environmental mycobacteria. Both ESAT-6 and CFP-10, two secretory proteins that are high...
