Phlebotomy Home Sample Kit

(2 customer reviews)

£99.00

This Phlebotomy Home Sample Kit allows you to return a professionally taken blood sample to our laboratory for testing using the most intelligent test on the market:

Please note:
You will need to arrange your phlebotomy visit/blood draw yourself.
Blood tubes (5ml serum / SST vacutainer tube) and blood draw apparatus are not provided as part of the kit.

The advantages of this test:

  • Measures the strength of your vaccine response using this quantitative (S1 protein) test
  • The only test to categorise positive results into low, medium, high and very high
  • The only test to report IgM and IgG levels separately
  • Repeat testing using this test allows you to monitor your COVID-19 antibody levels over time, which are known to decrease at different rates in different people
  • This test has been validated against a SARS-CoV-2 virus neutralisation test, and antibodies detected by this test can stop virus particles (original / wildtype strain) from entering cells
  • Considerably more sensitive than other antibody tests – the only test that has been validated in mild and asymptomatic cases of COVID-19
  • A test designed and run by experts in immunology.

The Virtus antibody test was developed by Professor Sebastian Johnston and his team at Virtus Respiratory Research Ltd. Professor Johnston has more than 30 years’ experience of researching respiratory virus infections see https://www.imperial.ac.uk/people/s.johnston.

All of our kits are delivered free of charge, the next working day (if ordered before 2pm).

What does my antibody test result mean?

Receiving an overall result of “Positive” from our test confirms that you have either had a prior COVID-19 infection or received a COVID-19 vaccine and you have mounted an immune response against the virus that is detectable by our test. A positive result for either IgM or IgG gives an overall positive result.

An overall result of “Negative” means that any IgM or IgG antibodies to the SARS-CoV-2 S1 spike protein were not detected by our test. This could be because:

  • You have not previously been infected or vaccinated against COVID-19
  • You have been infected or vaccinated, but the antibodies you produced are below the detection limit of our test
  • You have been infected but your immune system has produced antibodies that do not bind to the S1 spike protein in our test

Who is this suitable for?

Anyone who would like to know if they’ve previously had COVID-19 or would like to test their immune response after vaccination.
This is the ‘have you had it’ test. If you currently have symptoms of COVID-19, you should follow government guidelines (
https://www.gov.uk/coronavirus). 

What’s the advantage of this test?

Two different antibody types (IgG & IgM) are tested and reported separately 

IgM antibodies are detectable earlier than IgG and can be an indicator of recent infection. Our tests measures both COVID-19 IgG and IgM antibodies and reports separate results for each, giving you more information about the nature of your immune response. Other tests only measure IgG or will report a combined IgG & IgM result.

Our test gives you a quantitative result & categorises your response 

If you have a positive test result, this test will also tell you how strong your immune response to SARS-CoV-2 is, with antibody levels reported as low, medium, high or very high.
This will also be given a numerical value, which gives you a baseline measure so you can check in the future whether your levels have changed over time.

Antibodies that our test detects have been shown to protect against SARS-CoV-2 infection using a neutralising test 

This test has also been validated against a SARS-CoV-2 neutralisation test, which determines whether the antibodies in your blood are able to stop the SARS-CoV-2 virus from entering and infecting cells. The antibody levels measured by our test correlated very strongly with virus neutralising activity, meaning they blocked the virus (original strain) from infecting cells. 

Determines vaccine response 

All current COVID-19 vaccines are designed to produce antibodies to the S1 Spike protein, which our test measures. You can use our test to determine your response to the vaccine and booster and to monitor your antibody levels over time.

How accurate is this test?  

This test has been shown to detect 100% of severe hospitalised cases and 86.9% of 107 milder community cases, including asymptomatic people with a positive SARS-CoV-2 swab test, this is the test sensitivity. Most other antibody tests have not been validated in community cases of COVID-19, nor in asymptomatic people with a positive SARS-CoV-2 swab test.

For high or very high positives, the specificity of our test is 100%. This means for moderate to very high antibody positives, we are almost 100% certain they are not false positives. For moderate level positives, the specificity of our test is 99.5%. This means for moderate antibody positives, one in 200 tests could be a “false positive”. For low-level positives, the specificity of our test is 98.6%. This means for low antibody positive, 1.4 in 100 tests could be a “false positive”.

Note that in Prof Johnston’s view, a “false positive” is probably more likely to be showing cross-reactive protection from prior seasonal coronavirus exposure, rather than being a true “false positive”.

How quickly will I get my results? 

Results will be delivered via email (usually by 6pm) within 2 working days of receipt of samples in VirTus’ laboratory (Camden, London).

Return your samples using the pre-paid envelope, using any Royal Mail post-box. Delivery should be next day, unless Royal Mail is experiencing delays.

Is this an approved test? 

Yes, the home sampling kit and the COVID-19 S1 antibody test is fully CE marked (accredited), meaning that the products we use meet EU safety, health and environmental requirements and are approved for use within the European Economic Area (EEA).

Why would I choose this option instead of a finger-prick sample kit?

Some individuals prefer arranging a professional phlebotomist to take their blood sample, as they may find this option easier than taking the finger-prick sample at home.

  1. Karen

    I was sure I had coronavirus back in January. I got this test kit because I wasn’t too comfortable doing a finger-prick and a phlebotomist came to my house with all the PPE to take a sample from my husband and I. Great service!!

  2. Janet

    The phlebotomist was really nice and the instructions were easy to follow
