Private Coronavirus Antibody Test UK

What is the Covid-19 Coronavirus Antibody Test?

The COVID-19 coronavirus antibody test helps identify the presence and level of antibodies to the Covid spike protein. This is useful to show whether you have previously come into contact with the virus or not. Predominantly, it highlights past infection but has some ability to check for current infection. However, due to a limited test window, it does not provide the same level of accuracy as a PCR swab coronavirus test which is the test of choice during an active infection.

In all of our clinics, we are able to offer a quantitative spike (S) protein antibody test, also known as the Anti SARS CoV-2 S test. We also offer a home antibody test. 

Our test is run at London’s largest and most reputable UKAS ISO15189 accredited laboratory and is manufactured by one of the global leaders in Covid testing.

When should you get a coronavirus antibody test?

If you have had symptoms of coronavirus, you should only come into clinic after you have completed your self-isolation period and your symptoms have passed. The Anti SARS CoV-2 S test is most accurate when taken 14 days or more after exposure to Covid-19 or vaccination.

The Elecsys® Anti SARS CoV-2 S has internally validated and has been shown to be 99.98% Sensitive and 98.8% Specific in samples taken 14 days or later after positive PCR test. The presence or absence of antibodies does not definitively determine immunity to SARS CoV-2 but helps to numerically measure an individual’s antibody response.

If you have symptoms you should have the PCR swab coronavirus test to identify whether you currently have the active virus.

Please do not come into any of our clinics if you are currently showing any Covid-19 symptoms.

Please note home antibody tests are suitable for patients over 18 only. 

What is the Spike Antibody Test for?

By offering the covid antibody test, we hope to allow individuals to understand even more about their antibody status and how their antibody levels may change with time.

Many vaccines aim to cause an antibody response against the spike protein. By testing spike protein levels before vaccination and then at intervals afterwards, we may be able to better understand how different individuals respond to vaccines.

How accurate is the Spike Antibody Test?

The Anti SARS CoV-2 S test is most accurate when taken 14 days or more after exposure to Covid-19 or vaccination. The presence or absence of antibodies does not definitively determine immunity to SARS CoV-2 but helps to numerically measure an individual’s antibody response.

It is important to note that not everyone who has Covid-19 or has been vaccinated will develop detectable antibodies.

How do I get a Spike Antibody Test?

The Anti SARS CoV-2 S test is a simple blood test that we can do at any of our private GP clinics. Simply book an appointment at a time, and location, that suits you. We’ll email you with your results within 2-3 days. We also offer a home antibody test.  This test is a self-administered finger-prick test that is then sent via return post to our laboratory for analysis and results within 1-2 of them receiving it.

Frequently Asked Questions

Why should I choose your test?

We have carefully selected antibody tests designed and developed by two of the world leaders in the development of laboratory testing and equipment. The tests are both recognised and approved by Public Health England.

The test is run by our trusted partner Laboratory – The Doctors Laboratory.

They are the largest private laboratory in the UK, conducting testing for the NHS and are also delivering Public Health England approved COVID-19 PCR swab testing.

 

How accurate is your test?

The Elecsys® Anti SARS CoV-2 S has internally validated and has been shown to be 99.98% Sensitive and 98.8% Specific in samples taken 14 days or later after positive PCR test.

Does this test give me instant results?

We have opted for a laboratory-based test rather than a “pregnancy test” style kit, which means you are provided with the most accurate results. As such, results are not available instantaneously. The turn-around time is typically 2-3 working days.

Does a positive antibody test mean I am immune to COVID-19?

COVID-19 is still very new and we have a lot to learn. At this stage, it is unclear if positive antibodies will protect you definitively from getting COVID-19 again or how long antibodies will remain present. As such, it is important that you continue to follow Government guidelines and social distancing even if you do have antibodies.

Antibody testing helps us to understand who has been infected with the virus. This is information is essential in helping to understand the true spread of infections, how serious the infections are and most importantly help to establish if the preventative measures we have all been taking are working.

Additionally, it will help us to understand the risk of the virus in different populations.

In due course we are likely to learn if antibodies protect us against reinfection with COVID-19, research is ongoing.

What does a negative result mean?

A negative test result may have many meanings:

  1. You did not have COVID-19
  2. The antibody test was conducted too soon or too late after infection to be able to successfully detect the antibodies.
  3. You may have had COVID-19 but may not have mounted an immune response that caused the development of antibodies.
  4. There is a small probability of a false negative result

So, what’s the point?

Antibody testing helps us to understand who has been infected with the virus. This is information is essential in helping to understand the true spread of infections, how serious the infections are and most importantly help to establish if the preventative measures we have all been taking are working.

When should I have the test?

The Anti SARS CoV-2 S test is most accurate when taken 14 days or more after exposure to Covid-19 or vaccination.

Can I have the test if I have symptoms?

The antibody test is likely to be unhelpful, as it takes several days for antibodies to appear in the bloodstream.

You should have a PCR swab test which we can send directly to your home address.

Please do not attend our clinics if you are symptomatic.

How much does the test cost?

Home (self-collection) test

A home antibody test costs £60.

In clinic

An In-clinic Antibody test costs £70.

How long does it take to get results?

Typically, 2 working days after their arrival at our laboratory.

Your results will be shared with you through our patient portal, please provide a personal rather than work email address to avoid delays in receiving your results. Please do check your junk/spam folders if you think you should have received your results.
