Most tests to determine if somebody has already been infected with COVID-19 check for antibodies, but a new study in Italy found that those tests are much less accurate than a new type that looks for a type of immune cell called a T cell.
A new study on Duke University’s coronavirus testing and surveillance strategy highlights the importance of widespread testing of asymptomatic individuals to prevent transmission and provides support for the feasibility of a pooled testing approach, in which multiple samples are combined in a single test.
The Food and Drug Administration has authorized emergency use of a coronavirus test that costs $5 and can produce results in 15 minutes without the use of any lab equipment.
It’s still a way off, but a feasible, fast, at-home SARS-CoV-2 test is on the horizon. This new device being developed by Caltech will be able to detect coronavirus in ten minutes by analyzing a drop of your blood.
Between pop-up testing sites, doctors offices, worksite testing and self-administered tests, most patients don't know what type of coronavirus test they're taking — or how accurate it may or may not be, explained Dr. Shira Doron.
Experts say testing is a vital component to controlling the outbreak, but one test result still isn’t a green light to visit vulnerable friends or family members. The nature of covid-19, the time it takes for someone to develop symptoms and the varied ways the virus affects people make each test a snapshot in time more than a definitive answer.
A new STAT analysis of testing data for all 50 states and the District of Columbia, however, shows with simple-to-understand numbers why Trump’s claim is wrong. In only seven states was the rise in reported cases from mid-May to mid-July driven primarily by increased testing. In the other 26 states — among the 33 that saw cases increase during that period — the case count rose because there was actually more disease.
The United States is once again at risk of outstripping its COVID-19 testing capacity, an ominous development that would deny the country a crucial tool to understand its pandemic in real time.
Unfortunately, temperature checks could well join the long list of fumbled responses to the pandemic, from the testing debacle to federal officials’ about-face on masks. Because many contagious people have no symptoms, using temperature checks to catch them is like trying to catch tennis balls in a soccer net: way too many can get through.
You know how people often just 'sound sick'? Researchers are investigating just that. By processing speech recordings of people infected with Covid-19 but not showing symptoms, researchers found evidence of vocal biomarkers, or measurable indicators, of the disease.
