Roche CEO Severin Schwan Questions the Ethics of Certain Companies Making COVID-19 Antibody Tests and Calls Some of These Clinical Laboratory Tests a ‘Disaster’

Schwan’s concerns about inaccurate or unreliable COVID-19 serology tests were supported when the FDA issued more restrictive rules for these medical laboratory tests on May 4 Last month, Roche Group CEO Severin Schwan characterized some COVID-19 antibody tests as a “disaster” and questioned the ethics of some manufacturers of these tests. During a conference call with investors about the company’s first-quarter results, Schwan said of the recently-launched COVID-19 antibody assays, “These...

At MIT, New DNA Microscopy Maps Cells and Their Genetic Sequences Using Chemicals Rather than Light

Genetic data captured by this new technology could lead to a new understanding of how different types of cells exchange information and would be a boon to anatomic pathology research worldwide What if it were possible to map the interior of cells and view their genetic sequences using chemicals instead of light? Might that spark an entirely new way of studying human physiology? That’s what researchers at the Massachusetts Institute of Technology (MIT) believe. They have developed a new...

Human Antibodies in Medical Laboratory May Be Key to Immunity and Preventing Diseases Such as Influenza A

Scientists with Francis Crick Institute and Ragon Institute have successfully created human antibodies in vitro that can be made to recognize specific antigens in the human body; Could lead to new treatments for cancer and other infectious diseases It’s been long-recognized that the ability to design human antibodies customized to recognize specific antigens could be a game-changer in the diagnosis and treatment of many diseases. It would enable the creation of useful new clinical laboratory...

University of Pennsylvania Researchers Develop $2 Zika Proof-of-Concept Test That Needs Neither Electricity Nor a Clinical Laboratory to Return Accurate Results

Using 3D printing and a chemical heat source, University of Pennsylvania researchers have created a proof-of-concept for an affordable Zika test that returns results in just 40 minutes There’s a gap in Zika virus testing that researchers at the University of Pennsylvania hope to fill. That gap is a point-of-care test for the Zika virus that can produce a fast and accurate result, whether in developed nations or in developing countries that don’t have many state-of-the art clinical...

Researchers at Howard Hughes Medical Institute Develop Blood Test That Reveals a Patient’s Viral History; Could Reduce Unnecessary Clinical Laboratory Testing

The VirScan test gives doctors insight into a patient’s lifetime exposure to viruses and thus may be developed into a useful medical laboratory test Scientists and pathologists are learning that blood is like a time capsule, holding precious information about exposure to viruses over the years—chickenpox at five, mononucleosis at 18, flu at 40. You get the idea. Now, researchers at Howard Hughes Medical Institute (HHMI)  have found a way to tap that entire data stream, so to speak. An...
