DIANA Biotechnologies has developed a series of ultra-sensitive PCR-based diagnostic tests to fight the COVID-19 epidemic. These are optimized to be run in diagnostic labs in high-throughput format. Our COVID-19 tests are currently in use at over 30 clinical laboratories in the Czech Republic and also being exported abroad. We have already produced more than 6 milion COVID-19 tests, covering 40 % of czech testing capacity.
