As a result, I don’t think home tests are as effective as some might expect. When used on-screen for Covid, they could send millions of overweight people to lab tests and medical care.
The Kovid-1p epidemic spread around the world last year, Economist and scientist He called for a massive expansion of testing and contact detection in the United States to locate and isolate infected individuals. However, the number of daily tests in the United States has never exceeded 2 million Covid tracking project, And most of these were done in labs or on special instruments.
Tell their creators, home tests will now be made in the millions, but some experts are not sure that even the tests that worked perfectly will be able to change the epidemic picture a lot at the moment. “The real value of these tests was six months ago,” said Amitabh Chandra, a professor at Harvard University’s Kennedy School. “I think the over-the-counter move is great, but in a world where vaccines are more widely available, it has limited value.” “Vaccination certificates can be more important for travel and food than test results.
Companies that sell the tests say they have yet to find a relevant strategy to get them back to normal, especially children who have not yet been vaccinated. For employers who want to keep an office or factory open, self-administered consumer testing can be a good option. A spokesman for Abbott told me they could “help start thinking about a more coveted-conscious wedding shower, baby shower or birthday party combination.”
The UK government began offering free covid antigen tests in the mail and on street corners on April 9, saying it wanted to “get in the habit” of testing itself twice a week as social distance restrictions were reduced. In addition to vaccines, free trials are part of a plan to rid the country of the virus. Later though a leaked official memo hEthel officials were personally concerned about the false positive tsunami.
In the United States, there is still no national campaign around them for home tests or subsidies, and as a pocket expense, it is still expensive for most people to use any frequency. Based on my experience it might be the best.
The three tests we tried included two antigen tests, a kit from Binaknu and Alum from Abbott Laboratories, as well as a molecular test called Lucira. In general, molecular tests, which detect the genes of the coronavirus, are more reliable than antigen tests, which detect the presence of the virus’s outer shell.
Everything you need, except for the alum test, is in a box, which must be created with an application. Overall, the Lucira test was the best combination of advertised accuracy and simplicity, but it was also the most expensive at 55 55.
We did not test Quidel Quickview, another antigen test, or a molecule test of Q Health. These tests, although approved for home use, are still not being sold to the public.
Even after trying all the tests I am not planning to invest in using them regularly. I work from home and don’t socialize, so I don’t really need to. Instead, I plan to keep at least one test in my closet so that if I feel sick, or don’t smell me, I’ll be able to find out as soon as possible whether it’s Covid-19. The ability to test at home in the winter may become even more important once the winter and flu seasons return.
Time required: About 20 minutes
Price: . 23.99 for two
Attendance: In a few CVS stores starting in April. Abbott says it also tests a few million bilacans each month.
Accuracy: 84.6% for detection of Covid-19 infection, 98.5% for accurate detection of Covid-19 negative
This Home version The fastest, 15-minute test was used last year to screen White House staff and viewers. This is an antigen test, meaning it tests a sample from the nasal swab to detect a protein in the virus’s shell. It was sold in the US last week and I was able to buy a two test kit for বেশি 23.99 plus tax on CVS.
The technology used is called “lateral flow immunosuppression”. In simple terms, it means It works Like a pregnancy test. It is basically a paper card with a test strip. As the sample flows through it it hits the antibodies that attach to the virus protein and then the colored markers. If the ker virus is present, a pink bar appears on the strip.
I found the test to be fairly easy to perform. You use an eye dropper to deliver six drops of the chemical into a small hole in the card; Then you put a swab sert after running it around in two nasal passions. Rotate the swab counterclockwise, fold the card to bring the test strip in contact with the swab and that’s it. Fifteen minutes later, a positive result will appear as a pale pink line.
The test error is that there is room for two different types of user errors. Drops coming out of drops are too hard and too little use can be a false negative cause. So your nose may hang wrong. Unlike other tests, it cannot tell if you made a mistake.
And in addition to the possibility of user error, there are problems with accuracy in testing. Binakno is the cheapest test, but it is also the most likely to go wrong.
However, no buyer will find the rate of accuracy without digging into the fine print. The company also bury an important requirement imposed by regulators: to compensate for low accuracy, you are required to use both tests in separate kits for at least 36 hours. I doubt a casual buyer would understand this. The requirements for the two tests are specifically mentioned in the guidelines.
