Coronavirus infection study: Information sheet
Please note that this study uses a blood sample collection kit, not a lateral flow device.
Information sheet: UK Biobank's coronavirus infection follow-up study
We are inviting UK Biobank participants to provide additional help to support research on the SARS-CoV-2 coronavirus that causes COVID-19. The aim is to determine whether those vaccinated participants who tested ‘positive’ for antibodies to SARS-CoV-2 in our antibody self-test study developed these antibodies as a result of infection (rather than vaccination).
If you agree to help, we will send you a finger-prick blood sampling kit (the Thriva coronavirus antibody test kit) to obtain a small blood sample, which you will then need to post to a laboratory for analysis. Taking the blood sample is simple and quick to do. Once your sample has been analysed, you will receive your test results via email from UK Biobank.
Taking part is entirely voluntary and will not affect your ongoing relationship with UK Biobank. Please take the time to read this information carefully. It explains why we are asking you to help and what it would involve.
If you decide that you would like to take part after having read all of the information below, please log on to our participant website, go to the ‘Coronavirus infection study’ section then click on the “Join study” button to give your consent to take part in the study.
Thank you for your continued support.
This research study builds on the recent UK Biobank coronavirus self-test antibody study, which identified UK Biobank participants who had antibodies to the SARS-CoV-2 coronavirus that causes COVID-19. This additional study aims to determine whether the antibodies detected in those study participants resulted from SARS-CoV-2 infection.
You have been invited to take part because the results you returned in our coronavirus self-test antibody study indicated that you had antibodies to the SARS-CoV-2 coronavirus and you told us that you had been vaccinated at the time you took the test.
No; whilst we are keen for every invited participant to contribute, your participation is entirely voluntary. We do understand that you may not be able or wish to help, and this would not affect your future relationship with UK Biobank.
If you consent to join this study then we will provide your name and address in confidence to Thriva Limited who manufacture the blood sampling kits and who will send you your kit. (Note: They will not use your contact details for any other purpose and will remove them from their files after the study has been completed).
Instructions will be included explaining how to provide a sample of blood, as follows:
- Use the lancet provided to prick your finger and produce about 10 drops of blood (which is only about 1/10th of a teaspoon);
- Guide the blood drops into the tube provided, and then seal and label it;
- Return your blood sample to the laboratory in the pre-paid envelope;
- Wait to receive your test result, which UK Biobank will send to you by email.
Please note that the result will be sent to the email address that UK Biobank currently holds for you. If you are using a shared email address and would like it to be sent to a different email address, please change it by logging into the UK Biobank participant website.
When a person is infected with SARS-CoV-2, several antibodies are produced in response to viral proteins, including nucleocapsid and spike proteins. The vaccines currently approved for use in the UK only trigger antibodies against the spike protein, not the nucleocapsid protein.
Because the test we used in the self-test antibody study detected antibodies to the spike protein, it cannot distinguish between antibodies that are a consequence of infection or of vaccination. This additional study will use a laboratory-based blood test that can detect antibodies to the nucleocapsid protein. A positive test result will tell us that you have previously been infected with SARS-CoV-2.
All UK Biobank participants who took part in the self-test antibody study and reported both the presence of antibodies and that they had been vaccinated prior to taking the test are eligible to participate.
We advise people with certain conditions not to take a blood sample. These are:
- participants with untreated clotting or bleeding disorders
- participants who have had a recent mastectomy and there is swelling of the arm
- participants who are on renal dialysis
- participants who are HIV, Hepatitis B or Hepatitis C positive.
If you would like to take part, please log into the UK Biobank participant website using your Participant ID (PID) and personal details, where you can amend your postal address if required and complete our online consent form by clicking on the “Join study” button.
If you do not want to take part, please log into the UK Biobank participant website using your Participant ID (PID) and personal details, click on the “Join study” button and indicate that you do not wish to participate.
It may be a few weeks before a kit is sent to you, so we will email you before your kit is despatched to let you know when to expect it.
Please collect the sample as soon as possible after you receive your kit. You can take the blood sample at any time of the day (but please avoid taking it on a Saturday to avoid weekend mail delaying its receipt at the laboratory).
We may send you an email reminder if you have not returned your blood sample within 4-6 weeks of the kit having been sent to you.
The kit will contain full instructions about how to take the blood sample safely and easily. These instructions can also be found on our website, along with a video showing how to collect the sample.
If you consent to take part and then decide that you do not wish to provide the blood sample, you do not need to do anything. Dispose of the kit in your usual household waste and ignore any reminders to return your sample.
For the study findings to be useful, and so that we can incorporate the findings into the UK Biobank resource, it is important that the blood sample is not supplied by anyone else.
If there is a problem with your kit that prevents you from obtaining a blood sample, a replacement kit can be requested by logging into the UK Biobank participant website, clicking on “Request new kit” and providing details about any problems encountered with your sample collection kit.
If you have an adverse reaction, are harmed as a result of taking the sample, or had any other problems that did not require you to request a replacement kit, please contact our Participant Resource Centre on 0800 0 276 276.
Please complete the label supplied with your kit (on the return form), attach it to the sample tube and put this and your used and unused finger-prick devices into the specimen transport bag. Put the bag in the box your kit arrived in and put the box in the pre-paid envelope provided. Post the envelope as soon as possible after having taken your sample.
Your blood sample will be tested for antibodies to the nucleocapsid (N) protein that is produced following infection with SARS-CoV-2. You will receive the result of this test from UK Biobank via email within two weeks of submitting your sample.
Your test result will be incorporated into the UK Biobank resource and made available (in a de-identified form so that you cannot be identified) to approved researchers for research.
In accordance with the Health Protection (Notifications) Regulations 2010, COVID-19 antibody test results are required to be notified to Public Health England (PHE). This enables greater understanding of the spread of the virus, and the impact that vaccines are having on the ongoing pandemic, which will support future public health decisions. For more information, click here.
In order for UK Biobank to notify PHE of your antibody result, personal details including name, NHS number, gender, date of birth, postcode, and the result of your antibody test, will be transferred to PHE at the end of the study. You do not need to do anything and this will have no direct implications for you; you should continue to follow government guidelines and advice.
 Public Health England is an executive agency of the Department of Health and Social Care (DHSC). It fulfils the Secretary of State’s statutory duties to protect health and address health inequalities and executes the Secretary of State’s power to promote the health and wellbeing of the nation.
Yes. You will receive an email with the result of this test from UK Biobank within two weeks of sending your sample to the laboratory.
The tests carried out as part of this study are for research purposes only. We do not currently know if these antibodies will protect you from getting COVID-19 again. Therefore, whatever your test result, please do not make any medical or personal safety decisions based on the result of this test.
A positive antibody test will not confer any privileges, certifications or exemptions from existing HM Government or Devolved Administration COVID-19 guidelines. You should continue to follow government legislation and guidelines and self-isolate if you come into contact with somebody who has COVID-19.
You will receive information about whether you are likely to have been previously infected with the SARS-CoV-2 coronavirus in the last six months (and possibly longer), which may be of interest to you.
Your involvement will enable researchers to carry out crucial research into the long-term health effects of coronavirus (‘long COVID’).
Participation in the study involves collecting a blood sample using a finger-prick device called a lancet. This produces a small (less than 2mm) hole in the skin.
You may experience slight discomfort when using the lancet (people have described the feeling as a slight sting, much less than you would experience in a typical blood collection with a needle and syringe). As with any cut, there is a small risk of infection and/or bruising. However, the equipment is sterile and following the instructions provided in the kit (in particular, cleaning the skin before and afterwards) will minimise any risk of infection.
The process and products in the kit are similar to those used routinely for collecting blood samples for a wide range of healthcare purposes, including for home measurement of blood glucose levels in the management of diabetes.
Yes, this study has received ethics approval from the North West – Haydock Research Ethics Committee, 16/NW/0274.
The information obtained in this study will be treated in exactly the same way as all of the other data that we have collected about you. It will be stored securely by UK Biobank for many years, and provided only in a de-identified form (such that no participant can be identified from their data or samples) to approved researchers for medical and other health-related research (including scientists in other countries and in commercial companies).
We will put the results from all of these studies back into our database for other researchers to use. Scientists must make public the results of all research based on the resource so that everyone can benefit from it. You can find details of research that is being conducted using the UK Biobank resource and related publications on our website.
