The value of histopathology combined with CapitalBio real-time polymerase chain reaction test for diagnosing spinal tuberculosis.

Purpose: To evaluate the diagnostic efficacy of CapitalBio real-time polymerase chain reaction assay (CapitalBio test) in spinal tuberculosis (STB). The value of histopathology combined with the CapitalBio test in diagnosing STB was also assessed.

Methods: We retrospectively analyzed the medical information of suspected STB.

Clinical Application of the -RNA Assay of Pericardial Tissue Specimens in the Diagnosis of Tuberculous Pericarditis.

Purpose: To assess the accuracy of the (MTB)-RNA assay using pericardial tissue specimens for tuberculous pericarditis (TBP) diagnosis.

Methods: MTB culture and MTB-RNA assay were performed for patients with suspected TBP. The sensitivity, specificity, positive predictive value (PPV), negative predictive value (NPV), and area under the curve (AUC) of these two assays were analyzed.
