Private Coronavirus Antibody Test UK


What is the Covid-19 Coronavirus Antibody Test?

The COVID-19 coronavirus antibody test is a blood test which detects whether you’ve developed an immune response (antibodies) specifically to the SARS-CoV-2 virus. 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.

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 best time to antibody test is 14-21 days after your first symptom. The test we offer 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.  To find out more click here.

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

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

How does the COVID-19 spike antibody test work?

Antibody testing is done by having a blood sample taken in clinic by a doctor or nurse, or can be done at home via a finger-prick sample. It is then sent to our laboratory partner for analysis.

Previous testing kits have claimed to give you instant results (based on IgM and IgG antibodies), however, there are questions about the accuracy of these tests. Therefore, we recommend using a lab-based test. Lab-based tests guarantee that results are analysed in a controlled, sterile environment with minimum risk of contamination.

How reliable is the coronavirus antibody test?

Finding a reliable and safe test for our patients has been a priority for us. We have researched many products in partnership with our UK laboratory to ensure the test that we offer provides trusted results. Our laboratory uses technology created by leading brands for diagnostic tests. Our antibody test has been shown to be 99.98% Sensitive and 98.8% Specific in samples taken 14 days or later after positive PCR test.

The tests look for specific IgG and IgM antibodies, which appear during an established immune reaction. 

Antibody testing is a key pillar of the government strategy in boosting overall testing capacity for coronavirus. It is an important part of monitoring the spread of coronavirus. It allows an understanding of those who have recovered from the virus and is a key way to allow businesses to return to some element of normality until a vaccination is ready.

 

Type of Antibody Test Location Cost
Home (self-collection) Nationwide  £60 inc. postage
In-clinic  Any clinic £70 inc. appointment

 

What should I do if I think I have coronavirus now?

The PCR swab coronavirus test will help to establish whether you currently have the active virus. Please do not come into clinic and remember you and your household members will need to self-isolate for 10 days.

We are currently only offering in-clinic PCR swab tests in select clinics for anyone not currently showing COVID-19 symptoms. 

Because there is still so much unknown about coronavirus, we don’t know how long the antibodies will remain in your system. Other coronavirus antibodies, such as ones that cause the common cold, usually stay in the body for 1-2 years. Yet for more serious diseases, like MERS or SARS, the length is still unknown. We know from SARS that having the infection did not grant immunity. However, those experiencing a second infection seemed to have milder symptoms. We will not know whether this is also the case with COVID-19 until further research is available.

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.

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.

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.
