The Department of Molecular Biology at AEGEAN Medical. In recent years, molecular biology has been used increasingly frequently for the screening and diagnosis of diseases that are either difficult to diagnose using other methods or are caused by defects in an individual’s genetic material. Special mention should be made of Molecular Microbiology, a field that has gained particular diagnostic value due to the SARS-CoV-2 pandemic. Cytogenetic testing (karyotyping) of peripheral blood and other biological materials is performed. Viruses and microbes are detected and identified in various biological materials. Finally, various mutations and polymorphisms that cause diseases are tested. In this department, tests such as the following are performed:
