The U.S. National Institutes of Health (NIH) has waded into the controversial question of the respective roles of rapid antigen and polymerase chain reaction (PCR) tests for detection of the SARS-CoV-2 virus, a question that roiled relations between the FDA and public health experts. According to NIH, three rapid antigen tests administered at three-day intervals offer the same level of sensitivity as PCR, a finding that will likely make itself felt in future communicable disease outbreaks.

The FDA has given a green light to Foundation Medicine Inc.’s Foundationone CDx as a companion diagnostic for Takeda Pharmaceutical Co. Ltd.’s Alunbrig to identify patients with anaplastic lymphoma kinase (ALK)-positive metastatic non-small-cell lung cancer (NSCLC). The approval comes as Laboratory Corp. of America Holdings (Labcorp) is launching a companion diagnostic to identify NSCLC patients with the KRAS mutation. NSCLC accounts for about 85% of all lung cancers, with an estimated 1.8 million new cases diagnosed each year worldwide. Of those, 3% to 5% carry the ALK gene mutation, which is often missed with standard testing methods.

PERTH, Australia – With FDA approval of its Guardian system to detect early heart attacks, Angel Medical Systems Inc. (Angelmed) will launch the device in the next six weeks in the U.S., and partner Hydrix Ltd. will launch the devices in eight Asia Pacific markets.

Looking to allow customers to directly purchase its diagnostics system that runs a full panel of blood tests, Babson Diagnostics Inc. raised $31 million in new series B financing. The proceeds will be used to scale the Austin, Texas-based company to bring its finger-prick blood microsampling system to retail locations across the country.

An artificial intelligence (AI)-powered tool invented by researchers from a trio of Singaporean institutions could speed up the diagnosis of cardiovascular diseases. The innovation uses electrocardiograms (ECGs) to diagnose coronary artery disease, myocardial infarction and congestive heart failure.

Mfb Fertility Inc. received CE mark approval for its Proov PdG tests, giving European women direct access to information about ovulation without a prescription. The test enables a woman to test her urine for production of sufficient progesterone to confirm ovulation and favorable conditions for conception.

The U.S. Senate and the House of Representatives have reintroduced the Verifying Leading-edge IVCT Development (VALID) Act, a bill that would authorize the FDA to regulate lab-developed tests (LDT). The question of the agency’s statutory authority to regulate LDTs is part of a long-running debate, but the immediate question is whether Congress will see fit to deal with the question this year rather than wait until 2022, when the next device user fee will require legislative authorization.

Pattern Computer Inc.'s test for SARS-CoV-2 infection gives new meaning to rapid results. Taking 15 seconds from start to result, the test offers balanced accuracy of better than 96%, according to the company. The test is also not dependent on timing, unlike current antibody tests, and takes less time than point-of-care PCR tests. Its light-based system creates patterns based on a saliva sample, which is then matched against a previously developed model.

Princeton University spinout Neutigers Inc. is launching a study to explore the use of artificial intelligence (AI) and everyday wearables to flag early symptoms of sickle cell anemia vaso-occlusive crisis (VOC) before they get worse and land patients in the hospital. The aim is to reduce deaths and facilitate interventions to address the entire continuum of care for patients with the inherited red blood cell disorder, Adel Laoui, founder and CEO, told BioWorld.
