CE-Marked COVID-19 Antibody Kits for home use now available.

This new Coronavirus Antibody blood test looks for both IgM and IgG antibodies to SARS-CoV-2, the virus that causes COVID-19 and is approved to use finger-prick capillary samples obtained by lay-users in a CE Marked kit. It reports back actual antibody levels for both IgG and IgM as numerical values and these are classed as Negative, Positive (Low), Positive (Medium), Positive (High) or Positive (Very High).

How accurate is this test?

  • The tests and procedures undertaken by the laboratory we use to conduct this test are verified and performed in line with supplier product instructions for use and supported by additional validation data for use with self-collected capillary blood.
  • The test has been validated using the same methodology as PHE uses to assess tests it wishes to use, by testing against large numbers of SARS-CoV-2 proven positive samples (in this both hospitalised and community patients) and large numbers of “true” negative samples taken months before the first COVID-19 case in the UK.
  • The test has 98.1% specificity (true negative rate) overall.
  • The test has 100% sensitivity (true positive rate) measured against hospitalised cases after 14 days post exposure. It also has 91% sensitivity against community cases compared with just 69% for certain well known commercial assays (we legally cannot name the other asssay). This is the most sensitive assay that we are aware of.

What does a positive Covid Antibody result mean?

A positive result will confirm antibodies of the IgG or IgM class against Coronavirus SARS-CoV2 (Covid-19). This informs us, with a high degree of confidence, that the patient has been infected by this virus. The presence of IgG antibodies to a particular pathogen (infectious agent such as a virus) usually implies a degree of immunity to further infection from the same agent. Although in the case of Covid-19 it is not known yet to what extent immunity is conferred, and if so for how long, it is the opinion Professor Sebastian Johnston from VIRTUS Respiratory Research, based on previous literature with seasonal coronavirus infections that presence of a memory immune response to this virus is clear evidence of a significant degree of protection from the virus on future exposure, although for how long is still not understood.

What does a negative Covid Antibody result mean?

A Negative result means that this test was not able to detect any antibody that may have been produced. It is possible however that the patient could have been infected and have mounted an immune response that was not detectable by this test - either because the infection was mild and did not lead to the production of a detectable amount of antibody, because the antibodies produced bind a different virus protein to the one used in this test, or because the antibody levels have not yet risen to a detectable level. Repeat testing in 2 week’s time or longer following a negative result may lead to a positive result if this scenario is a possibility. It is also of course possible that COVID-19 infection has not occurred.

Increasingly it is being suggested that some individuals with a positive Covid 19 PCR (diagnostic swab) test result may never mount an antibody response that is detectable by antibody testing, and that the response in these individuals may be stronger via the immune system’s T cells; or alternatively that antibodies are produced, but for some only for a relatively brief period of time and that the level of antibody may then decline therefore becoming undetectable after a few months.

Quick Delivery, Quick return to lab, Quick results.      

These past months have seen sub-par delivery times from the Royal Mail, which is understandable given the circumstances. Because of seeing the impact of this upon our customers we upgraded to an expedited service. As of 21st May we have upgraded outbound deliveries further and now use a next day by 1 service for next working day delivery if you order by 1. In July we switched to dispatching kits from our operational address in order to further ensure quality of service.

Our service guarantees are to...

  • Dispatch your kit same day if you order by 1pm (m-f)
  • Send your kit by a Next Day Delivery Service - currently delivers in 1-2 working days
  • Provide you with a Royal Mail Tracked24 return envelope for returning your sample to the Laboratory.
  • The laboratory are typically emailing results now within 1 working day of sample receipt, but if very busy this could take up to 2 working days.

This latest development should see our customers experience a typical process time of 3-4 working days from ordering to receiving results if the kit is ordered by 1pm. Weekends not included.

Is there a discount for NHS, Carers and Key Workers?

A rebate of 20% is now available for NHS staff, carers and key workers. When you have ordered, simply upload a semi-anonymous picture of your official ID on our NHS rebate contact form with your order ID and we'll action your refund within 2 working days for you. Alternatively, if you have an NHS email address we won't need photo ID so use it to simply email Naomi on quoting your order number.
