NHS in talks to buy coronavirus tests themselves after the government returns home
The UK plans to roll out at-home coronavirus testing kits after ministers have been accused of taking thousands of infected people onto the streets without diagnosis.
Britain’s chief scientific adviser revealed that the government was reviewing the ‘easy to use’ blood tests that analyze antibodies in the body and diagnose them within hours.
They would be a huge improvement over the current nasal swabs used by the NHS, which take up to 48 hours to produce results and leave suspect patients in the dark.
The tests – known as serological tests believed to be free on the NHS – can also detect asymptomatic patients and those who have already reported the bug.
But Sir Patrick Vallance warned that it can take weeks or months for the kits to roll out, as health leaders aren’t convinced they are reliable enough.
The delay will cause more anger as other countries around the world use test kits that deliver results quickly.
In China, South Korea, Japan and Italy, a finer prick test has been used that takes only a few minutes to diagnose.

Finger prick tests such as the SureScreen Diagnostics device have already been used in other countries and it takes only a few minutes to diagnose. Although there is a question about how reliable they are
It comes after the death toll has risen to 137 in the UK and the number of infections has risen to 2,695 – although experts say the actual infection rate is likely to be over 80,000.
Sir Patrick told a press conference in London today: “Everyone is looking for a serological test. They have a few in some parts of the world.
“There are two types, one that requires lab testing and the other is an easy-to-use thing that you can use at home.
‘We are currently looking at both, but you clearly need reliability. That is the first. There is a danger that you have something that is not reliable enough. ‘
Sir Patrick added that the tests were conducted ‘as we speak’.
He said, “If you can test en masse, which would certainly be the idea, it will be very useful.
“It answers the question of which proportion of patients is asymptomatic, a really important unknown in this.
“Second, it can tell you who has had it and developed an antibody against it and therefore won’t catch it anymore.”
The tests would first be used by health professionals, who are essential in the fight against the virus.
Sir Patrick added, “It becomes important to understand who is safe to go back and work. Gives much more flexibility in terms of the NHS. ‘
“We shouldn’t dream that you can scale hundreds of thousands of tests a day. You can’t … it doesn’t happen overnight. It will be in a few days. ‘
Tonight, Chief Medical Officer Chris Whitty spoke at the Prime Minister’s daily press conference about the coronavirus press this evening. He said he was not sure that the current serological tests on the market were reliable enough.
But he assured the public that, over time, there will be one that is accurate enough to be rolled out, and said they will “gradually help normalize society”.
Dr. Martin Marshall, President of the Royal College of GPs, said there is a ‘shortage of available test kits’ in the UKD
The home tests work by picking up antibodies, the immune system’s defense mechanism, which fights the coronavirus.
Those with antibodies that respond to the deadly bug have already had it and recovered without knowing it, and are likely immune to reinfection.
In the UK, around 5,000 tests are performed daily, but these are usually reserved for patients already in the hospital.
About 100 general practices have agreed to conduct tests on patients as part of the surveillance to assess prevalence.
However, those who feel they have symptoms are told to isolate themselves without being tested routinely.
Boris Johnson has vowed to increase the tests to 25,000 a day, although he has not specified a timetable.
He also said that health workers will be a priority. Many have complained that they are forced to stop working because they are not sure whether they have the disease or not.
The World Health Organization’s message is “test test test,” to avoid trying to fight a blindfolded outbreak. South Korea says it has passed an outbreak with rigorous testing.
One of Britain’s top doctors today admitted that the UK is short on coronavirus studies,
Dr. Martin Marshall, president of the Royal College of GPs, warned that there are not enough test kits to go around Britain.
It comes after Prime Minister Boris Johnson promised yesterday that he would increase the number of people driven for the virus to 25,000 a day.
In the past five days, the UK has tested an average of 3,700 people a day – a total that the government’s chief scientific advisor has accepted is ‘clearly not enough’.
The British coronavirus outbreak has gotten out of hand and London is in the midst of an epidemic of thousands or tens of thousands of infected people. About 900 people in the city are officially diagnosed (Pictured, central London was devoid of traffic this morning)
Sainsbury’s in Northwich, Cheshire, opened early for retirees today so they could do their shopping before searching the shelves

Meanwhile, the US state of Tennessee – which is 10 times smaller than the UK – delivered 500,000 kits yesterday.
British officials have declined to disclose how many tests are available to NHS patients, but an offer the size of Tennessee’s could take months at the current pace of testing.
NHS employees across the country are crying out for testing so they can be sure they are safe to work with patients, and an online petition requesting it has been signed by nearly a million people.
Dr Marshall told Sky News, “At the moment, there is a shortage of available test kits for the conventional test currently in use. Hopefully that will improve in the coming weeks. ‘
Dr Marshall and the Royal College of GPs (RCGP) call for routine testing of NHS staff to ensure they don’t have to take time off, unless they are absolutely sick.
The number of health care workers is decreasing is a major fear of officials dealing with the epidemic.
It would make the impact of the coronavirus significantly worse because hospitals would be completely overwhelmed and unable to care for patients.
That is why schools are kept open for the children of NHS employees and recently retired employees are allowed to return to work.
Dr. Marshall added, “Routine health worker testing is not available …
“This should be a priority because many of my colleagues can’t work at home or maybe only work on the phone if they really want to support their team.
“They do that because they just don’t know if they have the virus.”
MailOnline is reviewing the advanced testing kits currently being rolled out in other countries and private clinics in the UK
FINGERPRINT TEST
Name: COVID-19 IgM IgG Rapid Test
Manufacturers: BioMedomics
Diagnostic time: 15 minutes
The blood test is not used in the UK, despite the medical authorities in China, Italy and Japan making the diagnosis in patients.
On March 5, BioMedomics claimed that its ‘quick and easy’ test was ready and was used in South Korea, Japan, Italy, China and some Middle Eastern countries.
After the blood sample is collected, a technician injects it along with some buffer into the analyzer – which is about the size of an Apple TV or Roku remote – and wait 15 minutes.
One line means negative, two lines in a staggered configuration means that the sample contains antibodies that the body begins to produce shortly after infection.
BioMedomics claims that its test can screen for coronavirus in 15 minutes with a small drop of blood and a small device that can be worn in the field
A blood sample is collected, inserted into the reader, a buffer combined and the results come back within 15 minutes, the company claims
Two lines closer to each other means that the person is positive for the antibodies at a later stage, and three lines means that the patient is positive for both types of antibodies.
A small study found that the test delivered a correct response 80 percent of the time.
PHE confirmed that it was not using the advanced blood test because it was not accurate enough and hopes to develop one itself. The U.S. Food and Drug Administration (FDA) has yet to approve it.
A former PHE strategist said he was “unsure” that the test could produce correct results and is therefore unlikely to be rolled out. However, the method was desirable.
NASAL SWAB
Name: TaqPath COVID-19 Combo Kit
Manufacturers: ThermoFisher
Diagnostic time: four hours
The DIY test detects specific DNA released by the coronavirus into the nose of infected patients.
Two men with suits were pictured with a ThermoFisher box – conducting coronavirus tests that yield results within four hours – outside Downing Street last night
Samples are then delivered to laboratories where they are analyzed and the results are produced within four hours.
The test was approved this week by the U.S. Food and Drug Administration, and 5 million kits will be shipped across America in the coming days.
We hope the UK will follow suit after representatives of ThermoFisher, based in Waltham, Massachusetts, entered Downing Street with a box of the tests last night.
It is clear that ministers gave a demonstration of how the test works.
FINGER STICK TEST
Name: COVID-19 Rapid Test Cassette
Manufacturers: SureScreen Diagnostics
Diagnostic time: ten minutes
The private company, based in Derby, has conducted a test that is said to be able to determine with 98 percent certainty whether a person is infected.
It involves taking a blood sample through a fingerstick and then placing it in a screening device.
SureScreen Diagnostics says a fingertip blood test is enough to determine with an accuracy of over 98 percent
The private company says the test has been validated and is already being used in the UK, Ireland, Germany, Spain, Switzerland, the Netherlands, Turkey, the UAE, Kuwait and Oman. Currently, it takes 24 to 48 hours for official swap-based methods to return
Public Health England cautions the public against the use of such tests for fear of being unreliable as there is ‘little information on the accuracy of the tests’
Results display in a similar fashion to a home pregnancy test within minutes and may potentially prevent delays in diagnosis.
SureScreen says the test has been validated and is already being used by private buyers in the UK, Ireland, Germany, Spain, Switzerland, Netherlands, Turkey, UAE, Kuwait and Oman.
It is believed that approximately 175,000 tests have been performed to date with the SureScreen kit. The company claims it received more than two million orders the following month.
Director David Campbell said, “We worked hard to create a coronavirus test (COVID19) that can be used on the patient’s side, with capillary blood, easily taken from someone’s fingertip, and diagnosed within 10 minutes can be stated.
“There is currently a major problem with the diagnosis of the disease because the standard method of screening is to send samples to the laboratory, which takes a lot of time.
“In the meantime, someone can spread the virus without knowing it, or have the problem of self-isolation.”
FACE MASK TESTS
Manufacturers: University of Leicester
Diagnostic time: 12 hours
How it works: breath test inserted in a mask
Scientists have launched a trial of the groundbreaking £ 2 gadget, which tests have already shown can detect tuberculosis, a deadly lung infection.

The researchers at the University of Leicester and the University of Pretoria designed 3D-printed strips of polyvinyl alcohol to be inserted into the mask (photo)
The masks, which could cost cents in larger production, are equipped with strips that absorb droplets from the wearer’s breath, which may contain traces of bacterial or viral infection.
The strips can be tested in laboratories with results that return within hours. Current tests for coronavirus can take up to 48 hours.
Researchers at the University of Leicester think it will take at least two months before they can test the masks on real COVID-19 patients.
But they are hopeful that it will work because it is a respiratory disease, which means it infects the lungs and it is present in the air, people exhale.
After 30 minutes, the strips can be tested in a laboratory (photo)
First, the team must test the gadgets on dozens of patients with other lung infections to prove that they can pick up bugs other than tuberculosis for which they were designed.
Patients with infections such as the flu and bronchitis have compared the results of their mask tests with those of throat swabs, which are known to be accurate.
Tests on tuberculosis patients, the only ones done so far, show that the masks can detect the deadly disease almost 90 percent of the time.
Professor Mike Barer and colleagues at Leicester hope they will be successful because the coronavirus infects the lungs in the same way as tuberculosis.
BREATH TEST
Manufacturers: Northumbria University, Newcastle
Diagnostic time: almost immediately
British scientists have developed a breath test that can quickly identify patients with coronavirus.
The technology, developed by a team at Northumbria University in Newcastle, is still under development and needs further testing.
But experts believe it can quickly change the way the virus is noticed around the world.

Dr. Sterghios Moschos said the test could yield results in minutes
The Northumbria team’s test collects breath samples that can be individually tested for biological information – also known as biomarkers.
These biomarkers, including DNA, RNA, proteins and fat molecules, can detect lung and other body parts.
People simply breathe in the device, similar to a blower used by the police.
Dr. Sterghios Moschos, an associate professor at Northumbria University, said, “Our ambition is to reduce the need for bloodletting for diagnosis in the broadest sense of the word.”
The test is currently being tested.
PRIVATE HARLEY STREET CLINIC
Manufacturers: Private Harley Street Clinic
Diagnostic time: three days
How it works: nose and throat swab
Price: £ 375
More than 2,000 people have ordered a £ 375 home test kit from a Harley Street clinic in London after being rejected by the NHS, according to the Daily Telegraph.
In addition to private individuals, some 60 companies, including oil and telecom companies, have bought them for their staff.
On its website, the item can simply be ‘added to the shopping cart’ just like conventional online products
Dr. Mark Ali, director of the Private Harley Street Clinic on London’s world-famous medical avenue, said his practice offered a new kit for £ 375 each
The test is placed at the client’s home or preferred address, where the client removes smears from both the nostrils and throat.
The sample is then placed in the supplied box and returned according to the instructions.
Dr. Mark Ali, director of the Private Harley Street Clinic on London’s world-famous medical avenue, said his practice offered a new kit for £ 375 each.
On its website, the item can simply be ‘added to the shopping cart’ just like conventional online products.
Practice says that the test is “conducted by a globally known UKAS accredited UK laboratory and that the test results are 100% accurate and require no further testing to confirm diagnoses.”
The website is hastening to add that while it oversees the entire process, patients should not attempt to collect their kits from Harley Street.
“Please note that under no circumstances can this test be performed at our clinic or collected from our clinic.” The website says.
“It will be sent to your designated address by courier within 48 hours. Consult the information below and order via the link at the bottom of this page. ‘
Dr. Ali told The Telegraph that he has received numerous requests from buyers.
“People are worried. They want to get some clarity in their lives, “he told The Telegraph.
“We have university students in England who want to return to Nepal, but they need to know if they have the disease so they can be left in their own country.
“We have a businessman who owns a construction company with sixty employees. He must know the state of affairs, otherwise he risks abandoning his customers. So everyone in that company gets tested. ‘
CT SCANS
Who came up with the idea? Mount Sinai Health System, New York
Diagnostic time: 1 hour and 30 minutes
How it works: detects lung damage
Doctors at the Mount Sinai Health System in New York say CT scans may be faster than nose and throat swabs when diagnosing coronavirus patients.
The team was the first in the US to analyze lung scans of patients in China with the highly contagious disease.
They said they could identify specific patterns in the lungs as markers of the virus, also known as COVID-19, as it developed over about two weeks>
Patients who received scans zero to two days after symptoms appeared had little to no evidence of lung disease in their results, such as this 19-year-old man who had a CT scan one day after the first symptoms
The team said the pattern in the lung of coronavirus patients is similar to scans of patients with SARS and very different from diseases such as bacterial pneumonia (photo)
The researchers say these faster diagnoses could help keep patients isolated in the early stages of the disease, perhaps even before symptoms appear and when they may not show up on other scans like chest X-rays.
“CT scans are an extremely powerful diagnostic tool because you can see the internal organs in a three-dimensional way,” said lead author Dr. Adam Bernheim, an assistant professor of diagnostic, molecular and interventional radiology at the Icahn School of Medicine on the Mountain. Sinai, told DailyMail.com.
“And you can see the manifestation of many diseases.”
For the study, published in the journal Radiology, the team analyzed scans from 94 patients in four medical centers in four Chinese provinces.
The patients had been admitted between January 18 and February 2 and had all recently traveled to Wuhan – the epicenter of an outbreak – or had come into contact with an infected person.
Radiologists reviewed the scan and took notes based on when the symptoms first appeared and when the CT scan was performed.
Thirty-six patients received zero to two days after reporting symptoms and more than half had no evidence of lung disease.
The team says this is important because it suggests that CT scans cannot reliably detect the coronavirus at the very early stages.
Nose and throat swabs can identify patients even before they become symptomatic, although some may still have the virus if they test negative first.
However, it can take days for the results to come back from the agency’s labs.
However, 33 patients who received scans three to five days after symptoms developed had patterns of ‘frosted glass opacity’ or blurring of the lungs.
“The lung abnormalities are very round in shape and affect the circumference of the lung,” said co-author Dr. Michael Chung, an assistant professor of diagnostic, molecular and interventional radiology at Icahn School of Medicine on Mount Sinai, at DailyMail.com.
