Escher Biomedical Diagnostics

Escher Biomedical Diagnostics is a private U.S. diagnostics and medical device company focused on pathogen detection technologies. The company is associated with the BT-MED platform, an automated molecular diagnostic system that uses in situ hybridization with fluorescent molecular probes and digital image analysis rather than RT-PCR. Its best-documented product is the BT-MED COV19 Saliva Test, developed for detection of SARS-CoV-2 infection in saliva samples for use in high-complexity laboratories. Available public information indicates the company was formed as a joint venture involving Biotrack BV and Echo Testing Group to commercialize this diagnostic approach in the United States. The company appears to operate in the life sciences diagnostics segment rather than therapeutics or drug development.
