The NULEXA system (formerly known as the VELO System under LEX Diagnostics) redefines point-of-care diagnostics by combining ultra-fast speed and high sensitivity in a PCR-based molecular system.

This breakthrough multiplex molecular diagnostics platform is the first to deliver true RT-PCR influenza A/B + SARS results in less than 10 minutes, directly from a swab sample.* The NULEXA System is CLIA waived and features proprietary technology and a cartridge-based design that eliminates the need for external liquid handling, delivering the speed, reliability and ease of use that fits seamlessly into busy point-of-care workflows.
