  • Results in 24 hours

Benefits of rapid antibody testing

  • 98.6% accuracy for IgG
  • Rapid result within 10 minutes
  • 100% sensitivity
  • 98% specificity
  • Simple finger-prick test compared to full blood draw
  • Easy on-site testing for companies, schools
  • Great value for money

Accuracy has been independently validated by Pasteur Insitute, Paris.

Rapid Testing for IgG antibodies

The instant antibody blood test tests for two types of antibodies – IgG (past infection) and IgM (current / recent infection).   Needing only a simple barely-noticeable finger-prick, using our comfort lancet, test has a 98.6% accuracy rate and 100% sensitivity for past infections (IgG). We are currently using Biozek COVID-19 antibody test kits.

The Biozek coronavirus antibody test kits are registered with MHRA and are CE certified. They are providing kits directly to NHS trusts and have sold 5 million kits worldwide, with multiple international registrations. They are produced by a Netherlands-based manufacturer. We are confident in the reliability of the test for IgG (past infection) antibodies and are running our own internal clinical audit as well as relying on studies from academic and health facility sources. 

If you are concerned about a current infection, we recommend having a PCR swab test for COVID-19 instead of or as well as the instant test as IGM sensitivity is less than ideal (around 92.9%).

A clinic certificate can be issued if this is needed. This test is only available at the clinic and is not regulated for home use.

Fee: £98 (50% discount for NHS colleagues, emergency workers and teachers – please show ID)

Laboratory Abbott Antibody Test

We are pleased to be able to offer Abbott antibody testing for coronavirus IGG antibodies. The government has correctly pulled home-testing for Abbott, a move we greatly support due to the difficult obtaining blood and issues with accuracy with home-testing. This test is should only be conducted at a clinic through full blood draw rather than finger-prick.

This test is 99% accurate for presence of antibodies and provides a certified laboratory report. Abbott testing requires the drawing of your blood and results can be available in 24 hours. This will give a positive or negative result but does not provide a quantitative result – ie. it tells you that coronavirus antibodies are present but not how many.

IGG antibodies are believed to start developing at around 14 days but we can be more certain at around 28 days. We do not know how these antibodies then behave – whether the levels drop over time, for example. This test is helpful as the threshold for finding the IGG antibody is lower in laboratory testing than the instant kit so if you only developed a few coronavirus antibodies or had very mild symptoms and probably therefore a low viral load, this test would help you get the answers you need.

Fee: £165 (50% discount for NHS colleagues, emergency workers and teachers – please show ID)

 

I currently have symptoms – what should I do?

If you are symptomatic, a swab test is currently available for at-home testing for COVID-19 with results in 2-5 days. This has close to 100% accuracy and is the gold standard for testing for a current infection. Similarly, if you need to absolutely exclude an active virus, either because you were previously ill or need to return to work, a PCR swab test would be the correct test to consider.

Fee: £165 for swab test only or £250 including a telephone consultation with a GP.

What ages do you test?

We can conduct phlebotomy for children over the age of 2.

Why do I have to have the Biozek test at the clinic?

These tests are not regulated for home use. The instant testing has a higher than acceptable level of inaccuracy when conducted at home by a non-medical person. The reason for this is that the process requires drawing of blood from the finger, quick pipette drawing before clotting and then processing in a cassette with processing fluids. The outcome of the test also needs interpreting – there are sometimes faint responses which need interpreting by someone experienced looking at the test outcomes.

Why are you offering both types of test?

The tests have comparable accuracy, although the Abbott is indeed a little more accurate than the Biozek test. However, some patients prefer the finger-prick over the full blood draw and some prefer an instant result rather than waiting 24 hours for the result. Patient choice is important to us so both tests are available.

So which test should I have?

You should make your decision based on your needs. You might need a laboratory report, for example, in which case the Abbott test would be best for you.  If you are testing for your own interest and don’t want a full blood draw, then consider the Biozek test. We have listed a list of benefits for each test above to help you make an informed decision.

Does having antibodies mean I am now immune?

The short answer is that we really don’t know yet. Logically, we can assume that having antibodies gives us a degree of protection for as long as we have them. Antibody tests show if you have had a previous coronavirus / COVID-19 infection and having IgG antibodies can mean that you are potentially immune to future illness. But we do not know yet what level of antibodies are needed to confirm immunity, if immunity is possible in the shorter or longer term and how long the IgG antibodies stay in our system. We will update our page as more studies are published and as we know more.

Can I still actively carry the virus if I have IgG antibodies?

We are too early in this outbreak to know for sure whether having IgG antibodies reduces the risk of transmission.

How do I book? Can I walk-in for my test?

Pre-booking is required. Because of the current climate, we cannot see patients on a walk-in basis. Please call us to arrange your visit or for your convenience, use our online booking engine.

Please note we are not seeing symptomatic patients at the clinic so if you have coronavirus symptoms and need testing for antigen, your best option is a home-testing swab kit and telephone consultation with a doctor. Please get in touch with us to arrange this.

 

About COVID-19

COVID-19 is a type of coronavirus that is highly infectious. It is passed on through droplets from an infected person. It is believed that around 50% of people carrying an active COVID-19 virus do not display symptoms which is one reason it has spread so quickly. Also, symptoms vary from person to person.

Some people only have a cough or a fever while others may suffer from a sore throat, headache, diarrhoea or lose their sense of taste or smell. The only way to know for sure if you have or have had coronavirus COVID-19 is through testing. 

Why do I need a consultation?

Testing without a consultation means that we would be unable to properly advise you on next steps, protecting your family, whether you can return to work after lockdown and any treatment you might require.

FAQs

How long after having symptoms can I have an instant COVID-19 antibody test?

The advice has changed a few times in the last few weeks as we all learn more about how this virus behaves but we are advising patients to wait for 28 days for IGG (past infection) detection. The PCR swab test can and should be done while you are ill (at home) or if you are concerned about having an active infection while asymptomatic.

I've read a lot online about the rapid tests being unreliable

We have sourced the best available currently and will continue to upgrade when improved tests become available. The media has correctly focussed on the lower reliability of instant tests for an active infection. We also do not recommend these tests for an active infection - we strongly recommend having the PCR swab test in addition to or instead of an instant coronavirus test. This test is however reliable in detecting a past infection with 98.6% accuracy and 100% sensitivity.

What does the Biozek rapid test involve?

The test is done on a blood sample taken from your finger. The blood drops are taken up into a pipette and then processed in a cassette with a reagent. It's quite fiddly which is why this test is not approved for home-use. It is intended for professional use only.

How long does it take to process the coronavirus rapid antibody test?

The COVID-19 antibody test takes around 10 – 15 minutes to process. First the control line appears - this has to appear to validate the test - and then if you are positive, either the IGM or IGG or both will appear. If none appear, you have tested negative.

Do you offer discounts for healthcare workers and teachers?

Yes, we offer a 50% discount and are committed especially in supporting our fellow healthcare workers the best we can. Booking is required and you can do so via our our online booking facility: https://www.harleyhealthcentre.com/booking. Please remember to bring work ID to the appointment with you.

Is the Abbott test validated by Public Health England?

Yes, the Abbott test was validated by PHE in May 2020.

Is the rapid coronavirus antibody test registered with any body?

Yes our test is registered with both the MHRA and FDA and is CE registered. You can read more about the Biozek antibody test here; http://biozek.com/corona-virus-covid-rapid-test/
