For some people, getting a positive coronavirus test could mean loss of income or other life disruptions. Doctors worry about growing disincentives to test and how this could prolong the pandemic.
New Yorkers who want to visit entertainment venues will be able to pull up a code on their cell phone to show they've been vaccinated against COVID-19 or tested negative.
The Food and Drug Administration gave emergency authorization to Ellume's rapid test in December, after it showed 96% accuracy in a U.S. clinical study.
The U.S. conducts nearly 2 million coronavirus tests daily. A new analysis shows millions more are needed to protect the most vulnerable. Use our tool to see how your state is doing.
Science writer Robin Marantz Henig has written about dangerous emerging pathogens for 30 years. But none of what she learned could shed light on her own confusing encounter with this virus.
The average wait time for results has dropped to about three days, but that is still too slow to keep infected people from unknowingly spreading the virus, researchers report.
Instead of running a coronavirus test on every specimen, a lab combines multiple samples. If the batch is negative, then everyone is in the clear. A positive leads to a second round of testing.
The standard test for infection with the coronavirus looks for a genetic fingerprint. Laboratory errors, including contamination, can lead to false results, a problem seen with environmental testing.
The CDC combines results of a test that spots people who are actively infected with another one that looks for antibodies. Scientists say it could create a false picture of the pandemic.
Almost 60,000 Ford workers were back on the job in the U.S. on Monday. Ford head Jim Hackett says the company's factories "create the distance that we're going to need for this to work well."
Representatives from a number of states said the list provided to them for coronavirus testing contained labs that they already knew about, or ones that weren't approved for the testing.
Two scientists at the McGovern Institute for Brain Research at MIT say the newly developed test is so simple it could conceivably be done in someone's kitchen.
These tests are designed to identify people who have been previously exposed to the virus. The Food and Drug Administration is now telling manufacturers they'll have to meet minimum standards.
An antigen test could be quick, and much simpler and cheaper than the PCR tests now used to spot people infected with the novel coronavirus. But some scientists worry about an antigen test's accuracy.
The announcement by Mayor Eric Garcetti makes L.A. the first major city to offer free testing to all its residents. It came as county health officials reported another 1,541 confirmed COVID-19 cases.
An APM Reports analysis finds that public labs — the first line of defense in an outbreak — in at least 10 states endured budget troubles or staffing shortages in the past decade.
New research suggests the Abbott ID NOW test, which produces results in less than 15 minutes, is the most likely among common tests to reassure people they are not infected when they really are.
Researchers are racing to develop quick, home-based tests for the virus that could deliver test results in minutes. None do that yet, but several under development hold promise, scientists say.
The CEO says "vastly more" COVID-19 testing is needed. The company is building its own lab to start testing some workers, potentially looking to start regular checks for all employees.
Antibody tests to detect past exposure to the coronavirus will soon be everywhere. But even the best ones can provide wrong answers surprisingly often — and give false assurance.
It is starting to take more time for cases, hospitalizations and deaths to double in several states, indicating social distancing is working. Here's how to make sense of those numbers.
Cuomo says 731 people died on Monday. "Behind every one of those numbers is an individual, is a family, is a mother, is a father, is a brother, is a sister. So a lot of pain again today," he adds.
The Wellness Matrix Group has offered customers an "at-home kit" for coronavirus testing that is "FDA Approved." But the agency has not approved any such tests, and customers say they feel scammed.
With a lack of tests, epidemiologists say the next best way to monitor the pandemic is by tracking hospitalizations. But hotspots like California and Washington are releasing little information.
