Design outcomes

Primary

MeasureTime frame
The primary endpoint in Subproject 1 is the test result of the novel NTM ELISpot assay. A one-time isolation of peripheral blood mononuclear cells (PBMCs) from whole blood will be performed, followed by ELISpot analysis using the novel test for NTMs, multiplex ELISA, and gene expression analyses for the investigation of immunological markers at the Institute of Immunology at Leipzig University and at Charité University Hospital. The primary endpoint in Subproject 2 is the detection of Mycobacterium tuberculosis on the membrane of the filter system. A one-time PCR analysis using the GeneXpert system will be conducted at the National Reference Laboratory in Borstel.
