How to Take the Lateral Flow Antigen Test by Project Screen

If you have bought a Lateral Flow Antigen COVID-19 test from Project Screen by Prenetics, this video will help you take the test in the right way. Please ensure you have access to the internet when you take your test.

About the Project Screen Lateral Flow Antigen Test

Lateral Flow Antigen tests provide a fast and effective way for people to travel safely between countries and socialise with other people without spreading COVID. Not all countries accept a lateral flow test, so do check the government list for more information.

How to Take the Test

A Project Screen Lateral Flow test is a little different from an NHS test as you must upload a photo of the result to your account on the Project Screen website. We will then verify the result and update your profile so that you can travel safely.

To take the test, you’ll need the contents of your box, which include:

  • Lateral flow cassette
  • Swab
  • Re-agent tube

It’s also worth having a bin to the side for your used materials.

Before taking the test, you’ll need to update your profile.

  • Scan the QR code with your mobile phone. Start by completing your personal details, including your passport number, name and address
  • Click on ‘activate your kit’ and choose Lateral Flow Antigen
  • Enter the code from the inside of the box

Now get everything ready for the test:

  • Read the instructions
  • Wash your hands for 20 seconds
  • Unbox the Lateral Flow cassette
  • Open the tube and place it in the card stand
  • Rotate the swab 5 times brushing against the inside of the nostril
  • Repeat on the other nostril
  • Put the swab in the tube to mix the reagent with your specimen and rotate for 30 seconds
  • Lightly squeeze the tube as you remove the swab extract as much specimen as possible
  • Add the dropper tip firmly onto the tube
  • Mix the solution thoroughly by swirling the bottom of the tube
  • Add 4 drops of the mixture to the specimen well on the test cassette.
  • Start the timer which is set for 15 minutes
  • After 15 minutes you can read the result
  • Do not interpret the result after 30 mins

Now you have to confirm the result. Choose one of the 4 options:

  1. Just C
  2. Both C and T (even if T is faint)
  3. Neither C nor T
  4. Just T

Then take a photo of the result and confirm the photo matches your submission. Place the rest of the test components in the waste bag and bin them.

Getting Your COVID 19 Test Result

Your COVID-19 test result will be released within a few minutes in the web app. During exceptionally busy times, please allow up to two hours. We’d recommend taking your test during business hours in case you need to contact our customer support team for queries or additional guidance.

Once your result is ready, you’ll be able to see it in the web app. We’ll also email you a notification for your records.

If your result is negative, you can set about your plans as normal. If your result is positive, follow the Government’s guidelines.

Good luck and stay safe with Project Screen by Prenetics.

Lateral Flow Testing

You may have heard the Government talking about Lateral Flow or Lateral Flow Antigen testing, which is a fast and affordable method of testing for COVID-19.

These tests are useful, as you can do them yourself at home, overseas, or under the supervision of a trained professional. The key difference between RT-PCR testing and lateral flow is that the test result is shown on a small handheld device.

How the Lateral Flow Antigen Test Works

The lateral flow antigen devices used by Project Screen collect cells from the nose which are then mixed with a reagent and placed into the lateral flow cassette. In about 10 minutes your result is indicated in the lateral flow device in the form of coloured bars.

You can do the lateral flow test in a personal or professional setting and get the results right then and there—this is slightly different from other types of COVID-19 testing:

  • RT-PCR tests send samples to a lab or for processing and typically take 24 hrs to turn around
  • OxLAMP technology can be used in settings like Airports where a mobile lab can provide results in less than two hours

Is the Lateral Flow Test for COVID-19 Accurate?

In a word: Yes.

While RT-PCR and OxLAMP tests are the most accurate, a press release published by the UK Department of Health and Social Care (March 2021) stated that: Lateral flow tests can show a specificity of 99.9%. This means, fewer than one false positive in every 1,000 tests carried out.

Further good news is that this research was carried out using millions of people which is important for scientific rigour. In the same article, Health Secretary Matt Hancock said:

“This new data further confirms what we know – these rapid tests are extremely accurate and are helping dramatically curb COVID cases. On Monday alone, we conducted over 1.5 million tests.”

It’s worth mentioning that these lateral flow tests were carried out in a supervised setting, which means that expert instruction was given to the participants and the test was processed by qualified individuals.

Lateral Flow Testing at Home

A huge advantage of lateral flow testing is that an individual can take the test at home and process their own test result.

To keep standards high, some precautions can be taken to maximise the accuracy of the lateral flow test. These include:

  • Having clean and sanitized hands
  • Working in a clean environment
  • Making sure that a good connection is made between the swab and nose
  • Ensuring enough sample is collected from the nose
  • Mixing the sample with the regent effectively
  • Reading the result after 10 mins, but before 20 mins

Lateral Flow Testing and Travel

Privately bought lateral flow tests can be used for travel in two main ways.

Travelling out of England 

For some countries lateral flow tests are applicable as a Fit to Fly test, whereas for other countries you will need a PCR test. Note, you can’t use an NHS test for travel purposes. You can read more about travelling to other countries in this blog post and in this government article.

Travelling into England

Before travelling into England, you’ll need to do a COVID-19 test three days before departure. As part of a round trip, starting in the UK, this is usually a lateral flow antigen test. Also note, you can’t use an NHS test for travel purposes. You can read more about travelling into the UK in this blog post.

Project Screen and Lateral Flow Testing

Lateral flow testing is both fast and economical, which means it’s great for testing people several times a week, for travel, or for events, professional and personal reasons.

Lateral Flow Antigen tests are part of our offer with Virgin Atlantic, where you can buy a bundle containing a lateral flow test, to suit your travel plans. For the destinations that Virgin flies to, we have a calculator to help you understand what kind of test you need.

We have recently used lateral flow testing with Mustard Foods, where we trained their staff on how to take a sample and run the test themselves.

About the Guided Self Swab method at Testing Pods

A new testing model; towards simplicity in 2021 for travel, work and events

“It would be an understatement to say my team was busy in 2020” said my new colleague, Hilly, as we introduced ourselves. It was my first day at Prenetics. I joined a session to plan for 2021, in what seemed to be a rare opportunity to look up and ahead for this team.

What I heard on in that session was:

  1. Our elite sport and film production clients are happy with the Covid-19 testing provided on their sites, but staff have asked for access to widespread locations.
  2. When travel, leisure and workplace activity increases, many more people will need safe and convenient covid tests, but a return of crowding and queues might actually make safety even more of a concern.
  3. Some customers feel information overload just trying to find a private coronavirus test, let alone watching a sample collection video and trying to organise a courier during a busy postal period. It’s not easy – certainly not the ideal start to a holiday or workday.

Local green testing pods

What if I could carry out a test near me, rather than queuing at the airport or in a crowded travel clinic? How can I avoid the effort of reading a hastily-made website, losing my confirmation email and forgetting how to provide my sample correctly. We set out to make testing easy by building a dream digital journey and taking the thinking out of providing a sample.

Key differences testing at a pod

Open-air

Drive up or walk up to the outdoor space. We know fresh air reduces transmission. For some of us on the team, it just feels better to not be indoors with other people who are getting tested.

Low-contact, digital journey

Book a test online from up to 190 time slots per day, create an account with your details only once, then forget about everything other than a QR code. The pod managers are behind glass and don’t touch your phone, so there couldn’t be less human contact.

Easy self-swab-and-drop

If I’m going to cough from the swab, I would prefer to be doing it myself. The magic is, the pod manager is guiding me step by step to make sure it’s done properly. It’s really worth trying the combination of controlling your own swab with someone else doing the thinking for you.

Our courier, Our lab

Again, do you want to read from 10 different sample return options or just leave the pod knowing that we’ve already organised for our courier to go directly to the lab at the end of each day.

National testing network

There were six weeks from the idea session to launching the first pods at Reading and Dartford, in England. Ten pods are ready to open at our next sites, then up to 30 and all the way to 300 covid testing pods throughout the UK. This is the contribution for summer holidays, getting back to work and attending events. Keep an eye out for more test pod locations popping up in the coming weeks.

Buying a Covid 19 test? Read this first

“I’ve done pretty much every Covid test out there in Europe and North America. It has taken me hours of research to make sense of what’s out there. For me anyway, the best for travel was the LAMP test at Heathrow, because I could complete the test on the day of my flight. And the easiest test was in the US – there are pop-up booths that are quicker than clinics or a home kit.”

This is a quote from when I spoke to my friend, Jivan, before the latest national lockdown. I realised how many testing options were out there and how hard it would be to decide with confidence. That’s a problem, especially considering that the test results really matter. Another friend I spoke to needed a test result on time in order to complete her emigration to Australia which had been 3 years in the making. Not to mention other risks we’ve become familiar with.

Why is choosing and trusting a covid test so complicated?

Any product that involves scientific technology requires concentration to understand. It’s not as easy as buying a sandwich or a pair of shoes. A lot of the information is new and changing, meaning there’s a learning curve which can seem long, particularly if a new rule is announced by an organisation or government. Having said that, coronavirus testing technology is more established now than it was a year ago, which is hopefully a good sign if or when we need tests for work, leisure and travel.

Where to start?

Whilst it’s tempting to jump straight in by searching online for private test providers, we’d advise taking a step back by finding what’s required by relevant authorities. In the UK, this is found on the UK government’s website which explains testing rules for different situations. If there’s another authority involved, such as an airline for your flight ticket, a company contact for your return to a workplace, or an event owner for your sports match, be sure to read their website FAQs alongside government guidelines.

What am I looking for?

Remember you don’t need to choose a test provider until you know what you’re looking for. Comparing providers before you know what you need is a one way path to information overload. Instead, try to specify what you need using a form like this one:

Has the government specified what
type of test I need?
Yes / No PCR / LAMP /
Lateral Flow
Has another authority 
specified what type of test I need?
Yes / No PCR / LAMP /
Lateral Flow
Are free government tests available near
me for the type of test I need?
Yes
Besides the type of test, are there timing
requirements to my sample collection
and result?
Yes24 hours result
48-72 hours from
sample collection
Do I have personal preferences for how to
provide my sample?
YesI want to drive
I’d rather walk
I’d rather do it at home
I like the idea of a nurse

If there’s no information from the government or another authority on which type test you need, have a look at our explanation of covid test types for help. 

I know what I need. I want to compare Covid-19 test providers.

We’d suggest finding a shortlist of 2-3 providers so you have enough choice without needing to spend time on too many different brands. Whether you want a lateral flow test next to your office or a PCR test at home within 48 hours of travel, the basic ways to qualify your shortlist is

  1. Covid test type
  2. Timing of sample and results
  3. Preferred sample collection location and method

Once you’ve got a shortlist of providers that definitely offer the test you need, within the time you need it, at the place you want to do it, you can make a final decision based on the extra factors that may be important to you personally. To see these, read our in-depth comparison that we use internally to make sure our products are both clear and attractive to customers.
