The viral assay, developed with Sentinel Diagnostics, improves the ability to monitor viral loads in critical organ transplant populations for the clinical management of infection.

The PCR diagnostic device is a palm-size, single-use, disposable device that detects N. gonorrhoeae and determines if it's susceptible to an antibiotic.

The firm will use the proceeds for working capital and other general corporate purposes, with the potential to acquire or invest in complementary businesses, technologies, or assets. 

The PCR viral load test runs on the Cobas 6800/8800 systems and has been calibrated to the World Health Organization International Standard, Roche said.

The tests use a range of different specimens including self-collected nasal swabs, bronchoalveolar lavage, sputum, and nasopharyngeal washes.

The firm generated $46.2 million in revenues compared to $53.5 million in the prior year, which was better than analysts' estimate of $39.6 million.

The genetic testing company said its orders for traditional tests have also rebounded and are on track for growth in the second half of 2020.

GenMark has two SARS-CoV-2 tests that have received FDA Emergency Use Authorization, including a respiratory panel that tests for 21 pathogens.

The firm delivered record revenue and the most profitable quarter in its history as a result of the increased demand for its products.

On an adjusted basis at constant exchange rates, revenues grew 19 percent year over year, in line with guidance provided by the company in early July.

Asuragen will develop assays for PacBio's long-read next-generation sequencing systems, with an initial focus on developing a carrier screening assay.

Zeesan's test may be used by any CLIA-certified high-complexity lab, while UCSD's test, which uses pooled samples, must be performed by the university.

Both tests can detect SARS-CoV-2 in 90 minutes and will detect viruses like influenza and respiratory syncytial virus that tend to occur in the winter.

The Clarigene SARS-CoV-2 IVD kit uses two viral RNA targets, nucleocapsid gene N and envelope gene E, which are specific to COVID-19, the firm said.

The company believes the pandemic will accelerate the adoption of its cancer diagnostics as patients and doctors look for faster and more convenient tests.

The company recently had a second pre-submission with FDA and expects to begin a prospective trial of its test in the second half of this year.

Regular SARS-CoV-2 testing could limit COVID-19 cases on university campuses but results might vary based on the schools' behavioral interventions.
