About

Blok BioScience is a leading health tech company that has created Immunity Passport to help businesses and individuals get back to normal as safely as possible. To do this, it combines cutting edge technology with real world logistics, to give people the tests, info and the tools they need to navigate this global pandemic. 

Immunity Passport is a tool that allows you to store your COVID-19 test results, symptoms and other key health data securely and privately. If you choose, you can share this record to demonstrate your COVID-19 health status, to gain access to workplaces, shops, businesses, leisure establishments and more. nnIt works using a combination of physical COVID-19 testing and supporting tech that analyses the data and compares it will the latest official health guidance. This gives you the info you need to make decisions about where you go and who you interact with. nnAnonymised data is collected to help employers and organisations catch any local flare ups quickly, and put protective steps in place to keep their People safe – creating safer spaces that follow our Covid Care Environments program. 

Antibodies are important molecules our immune system makes to help protect us against foreign invaders such as bacteria and viruses. 

Immunity Passport currently supports two types of antibody test – a rapid test you can do yourself and an even more accurate lab-analysed test. Other types of tests to detect current infection may be offered in future.

High-quality rapid finger prick tests are 90-95% accurate. They are not used for diagnosis of current infection, but to understand whether you have previously been exposed to the virus, recovered and have some level of resistance or immunity to reinfection. Lab-analysed antibody tests are more than 99% accurate.

Antibody tests are designed to tell you if you have been infected with the COVID-19 virus and have built up antibodies and some level of resistance or immunity to the virus. This is helpful to confirm if an illness you had in the past was, in fact, COVID-19. It can also tell you if you’ve had the infection and been asymptomatic. 

You may be given a test by your employer or by a service provider, such as your health club. In the future you will be able to buy antibody tests for your own use. At this time, you can also have a PCR test that checks for the presence of the virus itself, rather than antibodies, on the NHS. 

Using our tests and Immunity Passport

You need around two drops of blood so that it fills the well at the bottom of the test cassette. If you’re having trouble measuring enough, use the pipette.

A small sample of blood will be drawn from a vein in your arm, exactly like a regular blood test, by a healthcare professional. This will be send away to a lab to be analysed. You will be able to check the result a few days later on MyImmunityPassport.com.

 

There are two key types of antibody that battle COVID-19. IgM antibodies appear at the start of infection to fight the virus. These usually disappear once the body has killed off most of the invading pathogen. As the body defends itself, another kind of longer-term antibody, called IgG, is produced to continue to mop up the invader and be prepared to defend against future exposures to the virus. 

There’s still plenty that the scientific community doesn’t know about COVID-19 yet. At the present time no one can say with any certainty how strong the immune response is to future infection, or how long it lasts. The scientific community is understandably cautious about committing to any statements about a virus they haven’t studied for at least two or three years. However, reinfection is rare and what we know about our immune systems would suggest having COVID-19 does give you some protection against catching it again. 

A test can only give you a snapshot of your COVID-19 health status at the time you take it. To keep fully on top of your health status, you need to pay attention to how you’re feeling. Knowing what symptoms to look for and also being able to track how long you’ve been symptom-free is vital. This may be needed to return to your workplace or enter a commercial venue. 

Yes. The number and severity of symptoms varies from person to person so if you have any of the symptoms of COVID-19 as set out in your self-declaration, you may have the virus. To protect others, you should self-isolate until you can have a test to confirm whether you have the infection. 

Rapid finger prick tests are accurate to around 90-95% so if the result is not what you expect you may want to take a follow up lab test that has an accuracy of over 99%. It could be that the illness you had was not actually COVID-19, but had similar symptoms. It could also be that any antibodies you may have had have worn off – this varies between individuals are we don’t currently know exactly how long they last.

Unfortunately, the scientific community isn’t able to make that statement with any certainty at this time. However, in line with what we know about the human immune system, it seems likely that having COVID-19 antibodies will give you some level of protection against future reinfectionHow strong this protection is and how long it lasts for is not currently known. 

There are three letters on your test cassette – C, G and M. A line should appear next to the C, regardless of your result (this is the control line and confirms your test is working). If this is the only line you see, you are negative to both antibodies and do not appear to have, or have had, COVID-19.  nnA line next to the G means you have previously had the infection and now have antibodies. A line next to the M means you may be currently infected and may be infectious to othersIn this case, you should take all precautions, self-isolate and monitor your symptoms. You should book a test on the NHS to confirm whether you do indeed have COVID-19. 

Your risk level is the same as it has always been. You have not previously had COVID-19, but you may catch it in the future so should continue hand washing, social distancing and any recommendations from your employer and the NHS.

We know that some people can catch COVID-19 and not have any symptoms. This is thought to be rare, but means your body dealt with the infection very efficiently. 

Even a faint line indicates the presence of antibodies. Re-take the test to double-check. If the result is the same, assume a positive result. 

An invalid test may be caused by user error, a fault in the cassette or possibly some types of medication in your blood. You need to take a new test. Contact wherever you got your test and ask for a replacement. If a repeat test is also invalid, contact support@bloktesting.com.

Yes, this test is completely safe in pregnancy and while breastfeeding.

When you have a lab test, you’ll be given your Sample ID, which matches the number written on the test tube that’s sent to the lab. When you put the Sample ID into myimmunitypassport.com, it allows you to pick up your test results when they are ready. The Sample ID is very important and should be put into MyImmunityPassport.com at the time you have your blood drawn. The nurse will give this to you when you take your test.

Unfortunately, there is no way of picking up your test result without your Sample ID, so if you lose it you’ll need to have another test.

Your Access Code is a way to log in without needing to use personal data such as your name or email address. It’s unique to you and means you can update your COVID-19 health status whenever you like. It allows you to add multiple test results to your record, as well as symptom tracking, so you can keep everything together in one place. When the Immunity Passport mobile app launches later in 2020, you will be able to transfer all of your data onto your app using this code.

You can choose to have your Access Code emailed or sent to you by SMS. This does require you to give us your contact details. If you do this, you can search your inboxes to retrieve your Access Code. If you choose not to do this you will need to keep your Access Code safe as we will not be able to send you it if you lose it. We recommend you take a screenshot or write it down somewhere secure.

Your data

No. No one can see your test result unless you share it with them.

When the Immunity Passport native mobile app launches soon, all your data will remain on your phone. There is no central database. The mobile app is the only immunity passport globally that has received the highest standard for privacy, the ID2020 certification.

Use your QR code on the myimmunitypassport.com website to share the data requested by your employer or GP. Remember, only share what you’re comfortable with.

We recommend regular antibody testing to help keep up to date with your COVID-19 health status. You can add as many tests as you like to your Personal Health Record. You can also store your results if you take a PCR or other antigen test. Importantly, you will also be able to store your COVID-19 vaccine record on your Immunity Passport when vaccines become available. This is your permanent record and belongs only to you for you to use and share only as you see fit.

Your personal results are used by you alone. You may be able to show these to an employer, or use the test results and other factors including your symptom tracking, to generate a health status indicator for transport providers, bars, restaurants, gyms or other business to help them make sure their space is as safe as possible for you and other people to visit.

A “self-declaration” is what many companies, shops and leisure and travel providers may require in order to allow access to their establishments or services. Essentially, it is an honour system, whereby you “self-declare” whether you have any COVID-19 symptoms, or have been in close contact with someone that has been diagnosed with or presumed to have COVID-19, or that you have travelled somewhere that required you to self-isolate upon return. If you self-declare accurately, then everyone around you will be safer. And if everyone around you self-declares accurately, then you will be safer. We have to come together as a society during this pandemic to battle this virus effectively and keep as many people as possible safe and out of the hospital. Until there is an effective vaccine, this is our best strategy.
