Pulmonary tuberculosis diagnostic test using fluorescence immunoassay-based interferon gamma release assay with IchromaTM IGRA-TB.
Introduction: Tuberculosis (TB) is a serious global health problem in Indonesia, which is the country with the secondhighest TB burden after India. Accuracy in TB diagnosis is the key to effective treatment and decreased transmission rate. One of the latest diagnostic methods is interferon gamma release assay (IGRA), which measures the interferon-γ release associated with Mycobacterium tuberculosis (MTB) infection. This study aims to determine the diagnostic value of IGRA-TB using IchromaTM IGRA-TB diagnostic kit (sensitivity, specificity, positive predictive value [PPV], and negative predictive value [NPV]), compared to Ziehl-Neelsen (AFB) staining, nucleic acid amplificationbased test (Xpert-MTB) and chest-X Ray as the gold standard in TB diagnosis.
Materials and methods: A cross-sectional observational study design was used. Patients were recruited through purposive sampling from pulmonology outpatient clinic and inpatient ward at Jemursari Islamic Hospital (RSI Jemursari), Surabaya from July 2023 to December 2023. All enrolled patients should have been previously tested positive or negative for pulmonary TB using AFB staining, Xpert MTB and chest x-ray. Blood samples of the patients were collected and processed using the IchromaTM IGRA-TB diagnostic kit. The results were then compared with gold standard methods for calculating the IGRA-TB diagnostic value.
Results: A total of 56 adult patients were enrolled in this study. The sensitivity, specificity, PPV, NPV and accuracy rate of IGRA-TB using IchromaTM IGRA-TB diagnostic kit were 80.56%, 85%, 90.62%, 70.83% and 82.14%, respectively.
Conclusion: IchromaTM IGRA-TB showed reasonably high diagnostic sensitivity and specificity, indicating that this method can be further utilised as a diagnostic and screening tool for pulmonary TB.
期刊介绍：
Published since 1890 this journal originated as the Journal of the Straits Medical Association. With the formation of the Malaysian Medical Association (MMA), the Journal became the official organ, supervised by an editorial board. Some of the early Hon. Editors were Mr. H.M. McGladdery (1960 - 1964), Dr. A.A. Sandosham (1965 - 1977), Prof. Paul C.Y. Chen (1977 - 1987). It is a scientific journal, published quarterly and can be found in medical libraries in many parts of the world. The Journal also enjoys the status of being listed in the Index Medicus, the internationally accepted reference index of medical journals. The editorial columns often reflect the Association''s views and attitudes towards medical problems in the country. The MJM aims to be a peer reviewed scientific journal of the highest quality. We want to ensure that whatever data is published is true and any opinion expressed important to medical science. We believe being Malaysian is our unique niche; our priority will be for scientific knowledge about diseases found in Malaysia and for the practice of medicine in Malaysia. The MJM will archive knowledge about the changing pattern of human diseases and our endeavours to overcome them. It will also document how medicine develops as a profession in the nation. We will communicate and co-operate with other scientific journals in Malaysia. We seek articles that are of educational value to doctors. We will consider all unsolicited articles submitted to the journal and will commission distinguished Malaysians to write relevant review articles. We want to help doctors make better decisions and be good at judging the value of scientific data. We want to help doctors write better, to be articulate and precise.
