Abstract

In clinical practice, the diagnosis of tuberculosis (TB) continues to be a challenge. The goal of this study was to evaluate the reliability and impact of adenosine deaminase (ADA) enzyme testing as a biochemical marker in the continued management of suspected tuberculosis in a limited resource setting hospital. The retrospective data were collected from 2018 to 2021 and comprised the results of all ADA test assays done in the laboratory. All types of body fluids received for ADA testing were analyzed. Over the course of two years, 1461 samples for ADA assay testing were received. The average age of the study population was 56.69±11.7 years, with males accounting for the majority of the subjects (55.72%). Pleural fluid (N=817, 55.92%) was the most common type of sample received for the ADA assay. 114 (13.95%) of the 817 pleural fluid samples were found to be positive. A survey was conducted to obtain physician’s response regarding reliability on ADA testing. 100% of them reported the supportive role of ADA levels in the workup of patients with suspected tuberculosis. In a limited resource setting, the ADA test, in conjunction with clinical and other laboratory findings, can help physicians to initiate early treatment in hospitals for the benefit of patients.
