Investigation of the Clinical Diagnostic Significance of the T-Cell Test for Tuberculosis combined with Erythrocyte Sedimentation Test in Pulmonary Tuberculosis

Abstract

Objective: To investigate the clinical diagnostic significance of peripheral blood T-cell test (T-spot test) for tuberculosis (TB) infection combined with erythrocyte sedimentation rate (ESR) in pulmonary TB. Methods: 41 patients with a clinical diagnosis of TB during hospitalization from January 2020 to April 2023 in our hospital were selected as the experimental group, and 45 patients without TB (bronchopneumonia patients) were selected as the control group. The diagnostic specificity, sensitivity, and accuracy of the T-spot TB test, ESR test, and the combined test of the two were calculated respectively. Results: The sensitivity, specificity, and accuracy of the T-spot TB test combined with ESR for the diagnosis of TB in the experimental group were significantly higher than the individual results of the T-spot TB test and ESR test alone (P < 0.05). Conclusion: The T-spot TB test combined with the ESR test for TB diagnosis has greater clinical value than carrying out the tests individually.
