Georgia Esoteric & Molecular Diagnostic Laboratories, LLC @ AU (GEM)


Overview of Services

The Georgia Esoteric and Molecular (GEM) Laboratory, LLC at Augusta University, is a CLIA certified clinical diagnostic laboratory that provides state-of-the-art molecular diagnostics, cytogenetic testing and pathology consultation services. The lab offers diagnostic services and precision medicine tests for the diagnosis and evaluation of disease, primarily through molecular analysis of tissues and cells. The GEM Lab is also involved in the development of new molecular diagnostic tests. This includes identifying new technology platforms and techniques and incorporating them into the development of advanced molecular testing for human diseases. The overall goal of the GEM Lab is to develop and offer molecular based test panels that facilitate differential diagnosis, prognosis, therapy and management of diseases and malignancies.
