Inspector General finds FDA’s early COVID diagnostic policies came at a ‘cost to test quality’

As the U.S. gatekeeper for medical tests, how should the FDA strike a balance between making sure the public has options during a national emergency and making sure those tests actually work?  The Agency’s stumbles during the earliest stages of the COVID-19 pandemic hold some important lessons, according to a report from the inspector general of the Department of Health and Human Services (HHS).

At home blood pressure monitoring shows promise: Smartphone cameras could replace pulse oximeters to measure blood oxygen at home a study shows

Over the course of the last decade or so, smartphones have slowly morphed into full-fledged medical tools.  Mobile devices are now being used to read diagnostic test results, scan photos taken by their built-in cameras to spot signs of disease and even to take the place of pulse oximeters in measuring blood oxygen levels.

Discarded Compact Discs (CDs) Turned into Biosensors to Alleviate Waste: Researchers explore clinical application of biosensors made from CDs

A non-toxic, inexpensive process upcycles the little-used music technology into a health-monitoring sensor: An upcycling technique to isolate a compact disc’s thin metallic layer to create flexible biosensors that can monitor body function measurements such as oxygen levels and heart and muscle electrical activity has been developed by a team of researchers led by Binghamton University Assistant Professor Ahyeon Koh. “Everybody can create those kinds of sensors for their users. We want these to become more accessible and affordable, and more easily distributed to the public,” said Koh

Bio nanosensor can aid in depression diagnosis

A team of researchers at the Korea Research Institute of Bioscience and Biotechnology Research (KRIBB) has developed a biosensor capable of monitoring serotonin levels in real-time for diagnosing depression.
