Covid-19: Elon Musk says he examined optimistic AND unfavorable in similar day


Elon Musk has claimed he took 4 coronavirus assessments in a day, two coming again optimistic and two unfavorable, and declared ‘one thing extraordinarily bogus is happening.’ 

The Tesla boss, who has beforehand described lockdown measures as ‘fascist,’ tweeted Thursday: ‘Was examined for covid 4 occasions at present. Two assessments got here again unfavorable, two got here again optimistic. Identical machine, similar take a look at, similar nurse. Speedy antigen take a look at from BD.’

The 49-year-old might have been referring to Becton Dickinson’s Veritor Plus system, a 15-minute fast antigen take a look at. BD is a significant provider of assessments to the US authorities.

The FDA, which gave emergency authorisation to the BD take a look at, says any unfavorable consequence must be verified by molecular testing – essentially the most correct kind. 

Musk later revealed he was struggling ‘typical chilly’ signs and warned of the contradictory outcomes: ‘If it is taking place to me, it is taking place to others’.

The 15-minute, FDA-approved take a look at works by taking a nasal swab from a affected person.

The cotton swab is then put right into a tube and as it’s withdrawn the perimeters of the tube are squeezed in order that the liquid from the swab is caught inside.

A cap is positioned on the tube and the pattern is blended completely, both by swirling or flicking the tube. 

The contents of the tube are then dripped onto a stick-like machine which has a small pattern properly at one finish.

That stick is then left for 15 minutes earlier than it’s positioned contained in the BD Veritor Plus Analyzer machine. 

The machine appears for particular proteins discovered on the floor of coronavirus and turns round a consequence in a short time, exhibiting it on its show. 

FDA documentation for the BD take a look at warns that even a optimistic consequence ‘signifies the presence of viral antigens, however medical correlation with affected person historical past and different diagnostic data is important to find out an infection standing.’

As regards a unfavorable consequence, it says: ‘Damaging outcomes are presumptive. Damaging take a look at outcomes don’t preclude an infection and shouldn’t be used as the only real foundation for therapy … It is strongly recommended that these outcomes be confirmed by a molecular testing technique.’  

In October, Nevada well being officers ordered nursing houses to cease utilizing two fast antigen assessments after almost two-thirds of the assessments had been false-positive, or folks had been mistakenly instructed they had been contaminated with the virus.

The assessments had been the Quidel Sofia II and the Becton Dickinson (BD) Veritor Plus. 

The FDA underscored that studying the outcomes of an antigen take a look at too early or too late, or storing the diagnostics improperly, may end in false optimistic or unfavorable outcomes. 

Supply: FDA 

Their documentation for the BD take a look at warns that even a optimistic consequence ‘signifies the presence of viral antigens, however medical correlation with affected person historical past and different diagnostic data is important to find out an infection standing.’

As regards a unfavorable consequence, it says: ‘Damaging outcomes are presumptive. Damaging take a look at outcomes don’t preclude an infection and shouldn’t be used as the only real foundation for therapy … It is strongly recommended that these outcomes be confirmed by a molecular testing technique.’ 

Final week, the FDA stated it was alerting medical laboratory workers and healthcare suppliers that false optimistic outcomes can happen with COVID-19 antigen assessments.  

BD stated in September it was investigating studies from nursing houses that its fast coronavirus testing tools was producing false-positive outcomes.

In October, Nevada well being officers ordered nursing houses to cease utilizing two fast antigen assessments after almost two-thirds of the assessments had been false-positive, or folks had been mistakenly instructed they had been contaminated with the virus.

The assessments had been the Quidel Sofia II and the BD Veritor Plus, the latter being the corporate behind the assessments Musk stated he used. 

A number of Twitter followers joined in Musk’s dialogue questioning the inaccuracies and asking in regards to the eccentric entrepreneur’s signs. 

‘May this be why we have been seeing such a significant spike?’ one particular person wrote. 

‘If it is taking place to me, it is taking place to others. I am getting PCR assessments from separate labs. Outcomes will take about 24 hours,’ Musk wrote. 

‘Signs of a typical chilly. Nothing uncommon up to now,’ he replied to a different about his situation. 

Musk then appeared to take a swipe at firms creating the assessments, responding ‘precisely’ to somebody who wrote that the ‘revenues from assessments are possible not bogus & very constant.’ 

In a follow-up tweet Musk then added: ‘The carousel turns ever sooner.’ 

Musk has repeatedly downplayed the extent of the virus which has up to now killed greater than 242,00zero Individuals. 

Again in March, he fired off a tweet dismissing rising fears over the coronavirus outbreak as ‘dumb’ as instances continued to mount throughout the US. 

He then incorrectly instructed his 39 million followers that kids had been ‘basically immune’ to the virus and blasted the nationwide lockdowns as ‘de facto home arrest.’ 

Musk, 49, then responded to a series of comments from followers where he revealed he was suffering 'typical cold' symptoms and warned 'if it's happening to me, it's happening to others'

Musk, 49, then responded to a collection of feedback from followers the place he revealed he was struggling ‘typical chilly’ signs and warned ‘if it is taking place to me, it is taking place to others’

Musk then appeared to have a change of coronary heart, nevertheless, when he delivered over 1,00zero ventilators to a California hospital and vowed to reopen Tesla’s New York manufacturing unit as quickly as potential to assist make and distribute ventilators to the embattled state. 

However in September, Musk then doubled down on his claims that COVID-19 does not pose a threat to kids and stated he would not take a vaccine when it turned accessible. 

‘I am not in danger for Covid, nor are my children,’ he stated in an interview on New York Instances podcast ‘Sway.’ 

His most up-to-date feedback come as specialists have repeatedly raised issues in regards to the accuracy of fast assessments. 

Antigen assessments search for particular proteins discovered on the floor of coronavirus. They’ll return outcomes a lot sooner than PCR assessments, which detect the virus’s genes, however they aren’t almost as correct.

The FDA underscored that studying the outcomes of an antigen take a look at too early or too late, or storing the diagnostics improperly, may end in false optimistic or unfavorable outcomes. 

Final month’s replace additionally suggested giving a PCR take a look at to again up outcomes.

Seven antigen assessments have been given emergency authorization by the FDA. 

They’re made by Celltrion, Entry Bio, Quidel, Abbott, LumiraDx UK, Becton Dickinson and Quidel.  

Antigen assessments are useful screeners as a result of they’ll return ends in a matter of minutes. 

Fast outcomes imply that contact tracing can begin sooner and maybe cease additional transmissions. 

Or, if an individual will get a unfavorable consequence, they could really feel extra snug returning to work quickly, somewhat than ready days or every week to get again a PCR consequence.

Antigen assessments might be run on-site, sidestepping the issue of backlogs which have plagued the U.S. because the pandemic kicked off within the nation. 

However they’re simply not as correct because the ‘gold normal’ PCR assessments run in labs. 

In earlier steerage, the FDA warned that antigen assessments are usually much less delicate than PCR assessments, and usually tend to miss an an infection if they aren’t used inside 5 days of an individual’s first signs. 

That is partly as a result of antigen assessments do not amplify viral particles the best way that PCR assessments do, boosting the focus of the virus in a pattern, whereas diluting the whole lot else in it.    

The U.S. company stated false optimistic outcomes might happen when customers don’t observe the directions for the usage of antigen assessments for fast detection of SARS-CoV-2. 

MailOnline has contacted BD for remark.
