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.
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.
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.
