AIT Molecular Diagnostics, having a long-term and profound expertise in Biomarker- and Assay- Development, focuses on the identification of molecular markers for minimal invasive diagnostics. In this context we provide multi-OMICS analysis for biomarker discovery and establish targeted molecular assays for biomarker confirmation and validation. Along the development of minimal invasive assays for early diagnostics and precision medicine from body fluids (e.g.  “liquid biopsy”) we specifically focus on saliva as a new, promising and completely non-invasive sample matrix.
