The Next Generation Dx Summit is an annual event focused on advancements and innovations in diagnostics. It brings together professionals from academia, industry, and healthcare to discuss and showcase the latest developments in diagnostic technologies, tools, and strategies. As of my knowledge cutoff in September 2021, I don't have specific information about the Next Generation Dx Summit in 2023. To get the most accurate and up-to-date details about the conference, including dates, location, speakers, and registration information, I recommend visiting the official website of the Next Generation Dx Summit or conducting an internet search using relevant keywords such as "Next Generation Dx Summit 2023" closer to the event date. The official website should provide you with the latest information about the conference.
