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.

Duke study highlights importance of broad asymptomatic testing
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.
FDA gives go-ahead to fast $5 coronavirus test that doesn't require lab equipment
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.
A 5-cent sensor may detect COVID-19 in 10 minutes at home
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.
How Accurate Is Coronavirus Testing? It Depends On The Test You Take
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.
How to understand your coronavirus test results, from swabs to antibodies
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.
Trump said Covid-19 testing 'creates more cases.' We did the math
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.
U.S. Coronavirus Testing Could Fail Again
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.
Fever checks can't catch all Covid-19 cases. Smell tests might help
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.
Can we detect COVID-19 by analysing speech signals?
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.
