COVID-19 antibody testing

At-home antibody testing for social care staff  

Please note: the information on this page has been provided by NHS Test and Trace.


Antibody testing information

Please note: this information relates only to antibody testing.

Important note: care homes should remember that antibody testing is separate from weekly swab retesting and outbreak testing by PHE.  It is vital we continue swab retesting of all staff and residents in care homes. 

NHS Test and Trace have launched an at-home antibody testing service which is available to all paid staff aged 18 and over in the adult social care sector in England. 

What is an antibody test?   Back to top

Antibody tests are used to detect antibodies to the Covid-19 virus to see if you have previously had the virus. Our understanding of the body’s immune response to the virus is limited, and we do not currently know how long an antibody response lasts, whether you can be re-infected, nor whether having antibodies means you cannot transmit the virus to others. 

The test does not tell you if you currently have the virus.  

What are antibody tests used for?   Back to top

This at-home antibody testing service is supporting surveillance studies that are helping us to understand Covid-19 and how it has spread in the adult social care sector.  By participating and taking a test you will be contributing to this effort. 

An antibody test result can only tell you whether or not you have had the virus in the past and developed antibodies.  It does not tell you if you currently have the virus.

Important: regardless of the result of an antibody test, you must continue to comply with government guidelines, including wearing PPE and social distancing.

Guidance on PPE along with information about working safely in care home and adult social care settings is available here: 

Who can register for an antibody test?   Back to top

At-home antibody testing is now available across England to anyone employed in adult social care who is aged 18 and over. Personal assistants who provide for the care and support needs of adults are eligible, as are staff working in residential care, domiciliary care, extra care, supported living, and local authority adult social care departments. 

Antibody testing has been available to social care staff in some areas in England through the NHS. This at-home antibody test provides a new route to access an antibody test, giving greater flexibility and choice. You should only take one version of the test.  

If you are experiencing symptoms of Covid-19 or have received a positive swab test, you should wait 3 weeks before registering for an antibody test.

Local outbreaks in care homes   Back to top

If your care home is currently facing a local outbreak or suspected local outbreak, please wait 3 weeks after the outbreak before taking an antibody test. 

How do these tests differ from regular Covid-19 swab tests?  Back to top

Antibody tests are different to Covid-19 swab tests.  Swab tests tell someone if they currently have Covid-19, whereas antibody tests tell someone if they have previously had Covid -19 and have developed antibodies.  They do not tell you if you currently have the virus. 

Care home swab retesting of all staff weekly and residents monthly should continue as a priority, even if individuals receive a positive antibody test result.  If you are currently experiencing symptoms of Covid-19, you should follow government guidelines and order a Covid-19 swab test for free on the Gov.UK website.

Will my antibody test results affect whether I need a flu jab?  Back to top

Covid-19 and flu infections are different. The flu jab is a safe vaccination offered every year for free on the NHS to help protect people at risk of flu and its complications.

It is important to have a flu jab because it helps to protect the vulnerable people you work with. Also, research shows that if you catch Covid-19 and flu at the same time, you’re more likely to be seriously ill. 

If your antibody test shows that you have had Covid-19 in the past, you still need to have a flu jab. Whether you have had Covid-19 or not, the flu jab is still safe.  

Information about the flu jab and how to get it can be found on the NHS website. 

Taking the test   Back to top

To sign up for an at-home antibody test, you will need to register online on the Gov.UK site.  

After registering, you will receive a text message containing a code which will allow you to sign up for a test. All the equipment needed for the test, along with instructions and a link to a video guide, will be provided in the kit sent to your home. 

Results of the test will be communicated to you via text.   

Guidance and a video explaining how to take the antibody finger-prick test can be found on the Gov.UK website.

Wellbeing support  Back to top

As frontline care workers, we recognise the mental and physical challenges that Covid-19 may have placed on you.  It is important that you access support if you need it.  A service called Our Frontline offers support from trained volunteers plus resources to help look after your mental health.
