It was March 2020, and my plans to start out a brand new most cancers analysis challenge in Boston have been referred to as off for a similar motive every little thing else was grinding to a halt: coronavirus. Going through indeterminate months confined to my couch, I signed as much as a name for scientist volunteers circulated by the College of Cambridge.
The necessities weren’t very particular, and after virtually dropping hope that I’d ever hear again, I obtained a telephone name inviting me to help within the ramp-up of the UK’s testing capability.
Three days later, on the finish of March, I arrived with a handful of different volunteers at an industrial property close to the city of Milton Keynes, outdoors London.
Constructing a megalab
On the surface, the testing centre resembled a warehouse greater than a lab, however a formidable administration group together with lots of the UK’s main scientists had already been assembled. The group chief, who had arrived the week earlier than, launched us to the duty at hand: create a facility that might be the spine of the UK’s testing technique.
At this level, it appeared like a far-fetched thought to me. The “lighthouse” lab to course of the majority of the coronavirus take a look at samples hadn’t even been constructed and unboxed gear was piling up. There was no indication this is able to quickly grow to be the most important coronavirus testing website within the nation.
From the beginning, one of many greatest challenges was in gathering gear. Seemingly tough duties turned out to be easy, while trivial ones turned surprisingly intractable.
Difficult, costly machines donated from institutes throughout the UK have been put in inside a few days; producers massively ramped up manufacturing of refined take a look at reagents and we have been capable of construct up our shares.
However one thing as seemingly trivial as a scarcity of pipettes threatened to stall the entire operation, as 1000’s of checks waited to be processed. In an emergency like this it was useful to have a direct line to institute heads across the UK who have been keen to assist. Yet one more name and a military truck with dozens of pipettes and different gear arrived inside three hours.
In the long run, the collaboration between everlasting workers, scientists, exterior institutes, non-public corporations and the armed forces made it attainable to arrange a working lab inside a matter of days.
A motley crew of scientists
The volunteering scientists in my cohort have been a various crew: most of us had PhDs and had spent years in scientific analysis, however we initially shared a typical concern that few of us had expertise dealing particularly with coronaviruses. My very own experience investigating the molecular causes of Parkinson’s illness and most cancers appeared a far cry from viral diagnostics.
Because it turned out, there was little trigger for concern – the coronavirus take a look at is definitely fairly easy. At its coronary heart lies the Polymerase Chain Response (PCR) methodology, arguably one of the crucial broadly used strategies in molecular biology labwork and a process undergraduates college students be taught as a part of fundamental coaching.
In a PCR take a look at, the genetic materials of the virus is blended with enzymes that may construct and replicate viral DNA. Brief DNA sequences referred to as “primers” are then added. In a constructive take a look at the primers “recognise” viral genes and initialise their replication. Therefore, after we see extra DNA being produced, we all know that it should belong to the Sars-CoV-2 virus, and the PCR take a look at returns a constructive outcome.
COVID-19 checks: how they work and what’s in growth
All the newly arriving scientists had used the PCR method in their very own analysis many occasions earlier than and it rapidly turned obvious that coordination and good administration was a better problem than technical data of coronavirus biology if this unprecedented endeavor was to succeed.
Each week, dozens of recent volunteers have been recruited from high universities and institutes all around the UK. A few of us stayed in pre-arranged accommodations close by, others commuted from our residence cities. Every cohort obtained every week of intensive coaching and by the next week have been themselves coaching the subsequent consumption of volunteers below the supervision of a shift chief.
Inside two weeks, the location had modified past recognition. New labs had been fitted, robots had been put in, dozens of recent hires have been being skilled each week and my preliminary worries began to dissipate. I started to suppose, “We are able to really do that!”
With important gear put in, it was time to scale up. To an skilled scientist, performing a single PCR take a look at is easy, however working tens of 1000’s of checks a day is a distinct story.
Repeatedly easy issues turned out to be essentially the most important: “What’s one of the simplest ways to extract the pattern from its packaging?”, “Ought to the barcode be scanned earlier than or after the pattern is taken out?”, “At what second ought to the pipette be mounted with a pipette tip?”
Feeding a robotic with samples became a course of with all of the effectivity of a Method 1 pit cease. One operator takes out the outdated samples, a second replenishes take a look at reagents and a 3rd hundreds one other 94 samples – 10 seconds, finished. Quickly we had an built-in workflow of dozens of steps working in good orchestration.
Whereas velocity is essential, precision is important. A false unfavourable outcome may see a nurse with COVID-19 going again right into a care residence to contaminate dozens of susceptible sufferers; a false constructive would possibly see a wholesome physician despatched residence from ICU to self-isolate for a fortnight, or a key employee sending half their firm into quarantine for no motive.
To stop this, a pattern have to be tracked electronically and on paper at each stage. Each intervention by a scientist have to be supervised by one other to assist forestall human error.
As our group grew, strict coaching routines wanted to be established with clear guidelines. How do you write a “1”, an “I” and a “7”? Is that this a “5” or an “S”? How do you distinguish an “O” from a “0”? Lecturing skilled professionals about tips on how to write numbers and letters made me really feel absurdly pedantic, nevertheless it rapidly turned clear that frequent guidelines should be adopted religiously to minimise all attainable sources of error.
A month in, we had sufficient volunteers to work 24/7. I misplaced observe of the time of day and the times of the week. The day by day routine was ruled by the mantra of Tedros Ghebreyesus, the pinnacle of the World Well being Group: “Check. Check. Check.”
Again within the first week, the handbook pattern dealing with course of allowed a us to course of a few hundred samples. With extra volunteers coming in, this elevated to a few thousand, and after we roped in robots to assist, it rapidly reached tens of 1000’s of processed checks per day.
Identical to the unfold of the virus we have been competing towards, our capability was rising exponentially. What would usually have taken months or years to determine, now took days or perhaps weeks.
The attention of a political storm
The progress on testing has obtained a variety of unhealthy press and many people on the take a look at centre felt we have been being made personally chargeable for hitting authorities targets. This added stress precipitated frustration, particularly when everybody gave their easiest to make this endeavor successful.

We have to put issues in perspective. From a place to begin of zero, inside weeks, the joint efforts of lots of of volunteers allowed the lab to course of greater than 30,000 checks per day – or one take a look at each three seconds.
This put us able the place the processing of COVID-19 checks was now not the limiting issue of the testing initiative and shortly there was hardly a day the place our testing capacities have been getting used to the complete. The controversy now ought to be much less in regards to the accessible testing capability and extra on tips on how to make greatest use of what’s accessible.
The privilege of a lifetime
A lot of the authentic crop of recruits have completed their time on the testing centre and have gone again to their labs to proceed their earlier analysis. What stays as one of the crucial constructive takeaways from my perspective is that, regardless of the challenges and the nation’s seeming divisions, it’s nonetheless attainable for us to rally round a typical purpose. Volunteers joined the testing initiative from all corners of the nation, a lot of them from Europe and past residing and dealing within the UK, keen to assist out within the frequent effort to fend off the invisible enemy.
The work of those individuals has saved lives. It was my nice privilege to have been a part of this collaboration.
