Parameter
| Biomarker | MTB-DNA | Full name | Mycobacterium tuberculosis DNA | Molecular Type | Nucleic acid（DNA） |
|---|---|---|---|---|---|
| Molecular Formula | / | Molecular Weight | / | Core Functional Dimensions | Diagnosis, screening |
| Disease | tuberculosis | Disease Subtypes | / | ||
| Organ | Lung | Test Sample / Technology Platform | Tissue, urine, cerebrospinal fluid (CSF) (GeneXpert system, PCR) | ||
| Pathobiological Mechanisms | After Mycobacterium tuberculosis (MTB) infection, pathogen DNA is present in clinical samples, which directly reflects the presence of pathogens | ||||
| Clinical Availability Status | Clinical application: It has been widely used for pathogen angle disease identification, and the GeneXpert system is a common detection platform | ||||
| Notes and Dynamics | Sensitivity was high (98%) in smear-positive samples, but low detection rate in oligobacteriobacter samples | ||||
