Brief summary

The aim of this study is to identify new biomarkers that enable reliable, non-invasive diagnosis of tuberculosis (TB), including in patients who are unable to produce sputum. The study analyzes biomaterials (blood, urine, stool, sputum) collected from patients with suspected TB. Various diagnostic methods are applied to assess the feasibility of individual and combined biomarker tests. Participating patients will provide biomaterial samples (blood, urine, stool, sputum) once. No additional examinations or invasive procedures will be performed. Routine diagnostic procedures remain unaffected. This is a single-center, prospective observational study. Patients are enrolled as part of their clinical care at the University Medical Center Hamburg-Eppendorf.

Interventions

DIAGNOSTIC_TESTBiomarker-guided diagnostic tests

mRNA-Signature from blood; immunophenotyping from blood; MBLA from sputum, PATHFAST-LAM and EclLAM from sputum, stool, urine; CRISPR-Cas from blood; stool PCR; QuantiFERON(R)-TB Gold Plus.
