LEX Diagnostics is a privately held molecular diagnostics company developing products designed to enhance patient care by delivering clinical insights within minutes and at the time they are most valuable. Delivering a high-speed molecular test will redefine point-of-care diagnostics.
Our ultra-fast thermal cycling technology delivers sensitive PCR results directly from a swab sample in a user-friendly system. The LEX Diagnostics system fits seamlessly into primary care workflows, bringing the sensitivity of PCR to urgent care centres, physician’s office labs and pharmacies and at a much lower cost per test than competing molecular offerings.
LEX Diagnostics Ltd was founded in 2020 and joined QuidelOrtho in 2026.
We are based on the Melbourn Science Park, near Cambridge, UK.
