University of Washington: A smartphone’s camera and flash could help people measure blood oxygen levels at home
University of Washington: A smartphone’s camera and flash could help people measure blood oxygen levels at home. “In a proof-of-principle study, University of Washington and University of California San Diego researchers have shown that smartphones are capable of detecting blood oxygen saturation levels down to 70%. This is the lowest value that pulse oximeters should be able to measure, as recommended by the U.S. Food and Drug Administration. The technique involves participants placing their finger over the camera and flash of a smartphone, which uses a deep-learning algorithm to decipher the blood oxygen levels.”

Penn State: New at-home, saliva-based COVID test as effective as PCR in preliminary analysis
Penn State: New at-home, saliva-based COVID test as effective as PCR in preliminary analysis. “To bridge the gap between accuracy and convenience, Penn State researchers have developed an at-home, saliva-based testing platform that can provide results in 45 minutes.

11 Alive: FDA posts new expiration dates for some at-home COVID tests
11 Alive: FDA posts new expiration dates for some at-home COVID tests. “If you’re planning on using an at-home COVID test, one thing to always consider is the expiration dates. Experts warn that tests used after the expiration date may not provide you with accurate results. But how exactly can you find the expiration dates for FDA-approved at-home testing kits? And is the shelf life the same for different brands of tests?”
UMass Chan Medical School: New research shows value of at-home antigen tests in slowing spread of COVID-19
UMass Chan Medical School: New research shows value of at-home antigen tests in slowing spread of COVID-19. “Two recent studies supported by the National Institutes of Health Rapid Acceleration of Diagnostics (RADx) Tech program demonstrate how widespread distribution of COVID-19 at-home antigen tests can be used as an effective public health strategy to reduce the spread of the disease.”

NBC News: Incomplete data likely masks a rise in U.S. Covid cases as focus on infection counts fades
NBC News: Incomplete data likely masks a rise in U.S. Covid cases as focus on infection counts fades. “[Zeke] Emanuel and other experts cite a lack of testing as the primary reason cases go underreported. At the height of the omicron wave in January, the U.S. was administering more than 2 million tests per day. That had dropped to an average of about 530,000 as of Monday, the most recent data from the Centers for Disease Control and Prevention.”
