Antibody testing, which reveals whether or not somebody has had coronavirus, was to be a “complete sport changer” in England’s efforts to sort out the pandemic, prime minister Boris Johnson declared in March.

However though 10m assessments have been ordered from pharmaceutical firms Roche and Abbott in Could, only one.3m have to this point been carried out — nearly solely amongst NHS and care house employees. In the meantime, the federal government has indicated it has frozen its plans to roll out the programme to most people.

The scheme has foundered amid confusion over who’s eligible totally free testing and a debate round whether or not antibodies confer immunity from additional coronavirus an infection. This has led to concern amongst producers, who’ve been creating assessments at breakneck velocity in anticipation of a wider rollout.

Dido Harding, the ex-TalkTalk chief who’s main the federal government’s track-and-trace programme, stated final week that “at this stage the science isn’t clear sufficient” in regards to the hyperlink between antibodies and immunity.

She additionally revealed that there have been no instant plans to broaden antibody testing past healthcare employees. “At this stage it’s too early to say whether or not it’s or isn’t a game-changer,” she stated.

Simply weeks earlier, on Could 21, the federal government had introduced it was launching an bold antibody testing programme wherein tens of hundreds of assessments could be taken in England every day.

The division of well being and social care additionally appointed a gaggle made up of 4 firms, named the UK Fast Take a look at Consortium, to develop at-home antibody assessments to be used locally, setting them a goal of manufacturing 1m assessments every week. This was to be a part of a brand new UK diagnostics business being developed to fight the pandemic.

The testing programme, which centered on well being and care house employees, reached a peak of 240,000 antibody assessments in a single week in mid-June. However on 23 June, Scotland’s interim chief medical officer, Gregor Smith, despatched a letter to all UK NHS trusts advising that the “solely clinically protected possibility is to imagine no significant immunity from a constructive consequence” due to the “danger of unintended penalties if a constructive result’s taken to deduce immunity”.

The letter, seen by the FT, went on to state that the present proof doesn’t assist providing on-demand antibody testing to well being and social care employees or NHS sufferers. Testing has since dropped by greater than two-thirds from its mid-June peak, to 63,000 up to now week.

“I don’t see what they’re making an attempt to realize with this antibody testing programme,” stated Richard Tedder, visiting professor in medical virology at Imperial Faculty London, who invented the HIV antibody take a look at within the 1980s. “Individuals within the well being service have extra essential issues to be doing, and there are in all probability 15 causes they’d select to not give the assessments. This was a typical authorities numbers sport and it’s futile.” 

The ambivalence round testing has left producers in limbo. To date, only some assessments have been endorsed by Public Well being England — together with Abbott and Roche’s — regardless of lobbying from a variety of producers.

The UK Fast Take a look at Consortium stated it had obtained constructive outcomes from its finger-prick take a look at in late June, and is in negotiations with the Division of Well being on an settlement to produce as much as 1m assessments every week by the tip of the 12 months, pending regulatory approval.

Different firms vying to get their assessments authorized embody Mologic, a UK-based medical machine agency which is within the late phases of creating and validating its personal assessments, and SureScreen Diagnostics, recognized for its being pregnant assessments. Mologic, which despatched its take a look at to PHE for validation in late April and has nonetheless not heard again, stated its take a look at would price £2 within the UK.

Joe Fitchett, medical director at Mologic, stated the assessments have been essential for figuring out the situation of latest pockets of transmission and for asymptomatic instances. “The actually essential reality is we are going to by no means know the dynamics of antibodies until we take a look at for them,” he stated. He criticised the testing programme’s lack of “a decentralised and complete technique”.

The Division of Well being and Social Care stated, “each day testing numbers fluctuate however for the reason that Authorities rolled out antibody testing on 21 Could we’ve got carried out greater than one million assessments. The Authorities’s technique has not modified, antibody testing within the NHS and care sector is a key a part of the testing programme”.

However to some immunology specialists the ebbing enthusiasm for antibody testing within the UK isn’t any dangerous factor.

“They’re barely pointless of their function, so it’s not a foul factor that numbers have gone down,” stated Professor Jon Deeks from the biostatics division at Birmingham College who wrote a scathing critique of the federal government’s preliminary evaluation of the Abbott and Roche assessments. “There was by no means any clear technique as to why they have been being rolled out.”
