COVID-19 Antibody Tests

Clinic Appointments

Our COVID-19 antibody tests can help identify if you have previously been exposed to COVID-19. We offer customers the choice between finger prick tests (point of care tests) with results provided in 10 minutes or venous blood tests which involves a blood sample being sent to our partnered laboratory for analysis with results provided within 24 hours at the time your samples arrive to the lab.

The only method currently approved for antibody testing is for a clinician to take a blood sample.

All of our tests are carried out by our trained registered nurses in clinic.

COVID-19 Antibody Tests - IgG & IgM Antibody Tests

It has become increasingly important for the swift testing of individuals who believe that they may have come into contact with the virus. We offer those who want to be tested two options for COVID-19 Antibody tests:

Option A - COVID-19 IgG/IgM Antibody Venous Blood Test

A simple blood test taken by our registered nurses in clinic in which you will receive your test results via email within 24 hours from the time your samples arrive at the lab. You will also have access to our team of nurses to discuss the results if you want to.

We’ve partnered with an UKAS registered laboratory to do our testing.
Results provided 24hrs from the time your samples arrive at the lab
You’ll have access to our nurse helpline should you have further questions or concerns.
The antibody tests for specific “IgG” & “IgM” COVID-19 antibodies.
Results available to Public Health England.
One transparent price which includes the test, clinic appointment and follow up advice.
99.6% accurate.
Certificate provided for travel if required from our partnered laboratory

Please note if you do not wish to have your results shared with Public Health England you should not have the test. The laboratory will provide a qualitative result; reported as Negative, Positive or Equivocal with a comment and not quantitative/number.

What is IgM?

Immunoglobulin M (IgM) is the largest immunoglobulin in humans and is the first antibody to be produced upon infection. Since it has multiple antigen binding sites, it can be thought of as a ‘general’ antibody and is compatible with many pathogen species/types. In the case of COVID-19, IgM levels in the blood rise to a detectable level 3-7 days after infection, as symptoms begin to appear.

What is IgG?

Immunoglobulin G (IgG) is a smaller structure and is produced in response to a specific antigen on the pathogen. Its levels rise later than IgM (>7 days) and indicates exposure to the SARS-CoV-2 sometime previously.

IgM Positive - what does that mean?

The result is positive for SARS-COV-2 virus specific-IgM antibodies and is indicative of early phase primary COVID-19 infection. Results from antibody testing should not be used as the sole basis to diagnose or exclude SARS-CoV-2 infection or to inform infection status, a follow-up testing with a molecular diagnostic (PCR) test should be considered to rule out infection in these individuals especially if exhibiting any symptoms.

This test should be interpreted by a health care professional in the context of patient history and symptoms.

IgG Positive - what does that mean?

Positive result indicates previous exposure to SARS-COV-2, this antibody test is not a diagnostic tool for active infection. This test should be interpreted by a health care professional in the context of patient history and symptoms.

Negative result - what does that mean?

An absence of antibodies means that it is likely that you have NOT had COVID-19. An absence of antibodies infers an absence of immune defence to further coronavirus infections.

What is the COVID-19 Antibody IgG & IgM Blood Test?

COVID-19 Antibody test detects the presence of the SARSCoV-2 specific IgG and general IgM for the qualitative diagnosis of early and late stage COVID-19. As mentioned, IgG is specific to SARS-CoV-2 and confirms secondary illness (usually >7 days), whereas IgM confirms primary illness (3-7 days). Both are elevated in the secondary illness and can be used to confirm diagnosis.

Technical data for COVID-19 antibodies:

Accuracy: 99.6%
Specificity: >99% while showing no cross-reactivity to non-SARS coronaviruses or other medical conditions.

Option B - COVID-19 IgG/IgM Rapid Test (Finger Prick)

There is no perfect test for coronavirus antibodies and rapid tests have understandably received criticism which is why we are using a CE marked COVID-19 IgG/IgM Rapid Test which can only be performed by a fully trained healthcare professional following government guidelines. The tests are manufactured in a certified laboratory in Switzerland (9001:2015 & ISO 13485:2016).

The only method currently approved for antibody testing is for a clinician to take a blood sample.
The test requires a finger prick blood sample which is taken by a fully trained registered nurse.
The antibody test is testing for the specific “IgG” & “IgM” COVID-19 antibodies.
Results provided within 10 minutes.
98.6% accurate.

What is the COVID-19 IgG/IgM Rapid test?

COVID-19 IgG/IgM Rapid Test is a CE Certified immunochromatographic assay for the qualitative detection of immunoglobulin G (IgG) and immunoglobulin M (IgM) antibodies against COVID-19 in human whole blood, serum or plasma specimens. This test should only be performed and interpreted by fully trained, healthcare professional. An immunoglobulin test measures the level of certain immunoglobulins, or antibodies, in the blood. Antibodies are proteins made by the immune system to fight micro-organisms, such as bacteria, viruses and toxins.

Technical data for COVID-19 IgG antibodies:

Accuracy: 98.6%
Sensitivity: 100%
Specificity: 98%

The Value of Detecting both IgM & IgG COVID-19 antibodies?

The combination of IgG and IgM can be used to detect early and late stage COVID-19, as well as long term immunity after recovery. In this context, it is important that the IgG is specific to SARS-CoV-2. Recently, IgG specific for the SARS-CoV-2 virus has been isolated from the serum of patients who had contracted COVID-19. This specific IgG and the generalised IgM can be used to assemble a simple lateral flow immunoassay diagnostic test for the novel coronavirus.

How much does the test cost?

We charge £99 for the finger prick tests (point of care tests) with results provided in 10 minutes or £119 for the venous blood tests which are sent to a UKAS registered laboratory for analysis with results provided within 24 hours at the time your samples arrive at the lab.

What do our patients say?

Fantastic Service

My partner was really ill back in March with suspected Covid-19. I had extremely mild symptoms around the same time. Unfortunately the GP couldn’t get a test out to us so we never knew for sure. He is a mechanic and has now returned to work so we were keen to know If he had definitely had it. I heard Wren Healthcare were offering these tests where we could find out on the spot! A nurse carried out a test on both of us and turns out we both had the virus back in March. Fantastic service and I would definitely recommend!

First class! Highly recommend

I wanted to take an antibody test after experiencing all known symptoms in early March. After extensive research into a number of companies, I landed at Wren Healthcare and need look no further. Their first-hand knowledge, expertise and support was second to none. It was confirmed after a 5-10 minute test I had antibodies for COVID-19. 5* service (you don’t even need to leave the house). Highly recommend.

COVID-19 Antibody Testing

Me and my family had our COVID-19 testing for peace of mind and to allow some of us to go back to work. The process was quick and easy, the nurses were extremely professional and health and safety conscious. The whole process took around 15 minutes and I could leave with my results at the end. I would highly recommend Wren Healthcare COVID-19 testing to anyone who is considering being tested.

Coronavirus Test

I recently had the coronavirus antibodies test and was very impressed with the level of professionalism i received. I wasnt sure how it would work but i was put at ease with how brilliant the nurses were and how easy it was. The process was explained to me beforehand and all measures were taken to ensure optimum hygiene throughout. I would recommend this to anyone thinking of having the test themselves.

Excellent service!

Great customer contact. Wren called within 24hrs & booked home appointment for next day. The nurse arrived promptly & was professional & absolutely lovely. Took all the anxiety of having a Covid test away. Highly recommended.

FAQ

frequently asked questions

What is the antibody test for?

The test looks for the presence of antibodies (produced by people with the virus to counteract the virus) against the COVID-19 virus.

Why would I do an antibody test?

To see you if you previously had COVID-19 and may have some immunity from it.

How much does it cost?

We charge each person £99 for a rapid test or £119 for a venous blood test.

How do I pay?

Please fill out a form below and we will give you. We will need to ask you questions around your current symptoms and arrange time/date for a nurse to visit you at home.

When will I get my results?

For the rapid tests you will get your results within 10 minutes during your appointment.

With the venous blood lab tests it will take 24 hours from the time your samples arrive at the lab to get your results usually 6.30PM the next day. You will receive your test results via email. You can call us on 0203 974 6950 to discuss your test results.

Will I be immune to COVID-19 after I test positive for IgG antibodies?

The link between the presence of antibodies and immunity is not proven. A positive test result for antibodies does not necessarily mean that you are immune to COVID-19. However, as we learn more about COVID-19 you will be in a better position to understand the implications of your test results.

Please follow government advice here

How reliable are the tests?

Rapid Tests: Our tests are 98.6% accurate in detecting COVID-19 antibodies. The tests are CE certified and our manufactured in a certified laboratory in Switzerland (9001:2015 & ISO 13485:2016).

Venous Blood Lab Tests: In clinical tests the Platelia SARS-CoV-2 Total Ab test demonstrated >99% specificity for SARS-CoV-2 while showing no cross-reactivity to non-SARS coronaviruses or other medical conditions.

In a study of PCR-positive patients, the assay detected antibodies in 100% of patients that were collected and tested between 9 and 22 days after onset of symptoms.

PLEASE NOTE: The link between the presence of antibodies and immunity is not proven. A positive test result for antibodies does not necessarily mean that you are immune to COVID-19. However, as we learn more about COVID-19 you will be in a better position to understand the implications of your test results.

Please follow government advice here

What is the difference between PCR and Antibody testing?

A PCR test involves analysing a sample collected from deep inside the nose or the back of the throat by a swab or the sample might be saliva or other fluid. The test can take from less than an hour to several days to get a result.

Antibody testing looks for the presence of antibodies (produced by people with the virus to counteract the virus) against COVID-19 virus.

Further advice on PCR & Antibody testing can be found on the government website here

Do lockdown rules apply if I am immune?

Following any antibody test you must still follow government advice on social distancing, hand-washing and isolation.

Having antibodies simply makes it more likely that you will not have a second infection or, failing that, that a second infection would be milder compared with a similar person who has no such antibodies. However, it is still not proven that you immune from COVID-19 once you have developed the antibodies.

Can you test my children?

Unfortunately we can only tests adults. Anyone over the age of 16 we can test.
