Do you want to know if you have immunity to Covid-19?

Our advanced laboratory Covid‑19 antibody test will tell you if you have any antibodies to help fight a Covid-19 viral infection, either from having been infected with coronavirus in the past, or from being vaccinated.

Our advanced laboratory Covid‑19 antibody test will analyse a sample of your blood to detect the presence of Covid-19 specific antibodies, including Immunoglobulin G (IgG), the most common type of antibody. Your results will tell you if you have been exposed to Covid-19 in the past by determining the amount of Covid-19-specific antibodies in your bloodstream.

Your report will provide a quantitative result that relates to the level of Covid-19 antibodies within your sample and whether the level is low, medium, high or not detected.

Example reports

Antibodies not detected

Medium antibody levels

High antibody levels

Antibodies from Infection or Vaccine

Tracking your IgG levels will give you an indication of your level of immunity to a SARS CoV-2 infection. This new and innovative laboratory antibody test is designed to give you peace of mind about the level of protection you have from either vaccination or natural exposure to the virus. It will potentially highlight those people who have a poor immune response and therefore need to take extra care.

If you order an antibody immunity test from AlphaBiolabs, you will be sent an easy-to-use sample collection kit to collect your own blood spot sample in the comfort and privacy of your own home.

The kit comes with free delivery plus clear and simple instructions on how to collect your sample and send it back to our UK-accredited laboratory, using the pre-paid tracked envelope included.

Understanding your results

Your laboratory report will show the level of Covid-19-specific antibodies in your blood sample. The level could range from antibodies not being detected at all, to an optical density range of 0.25 (a very low level) at the lower end of the antibody concentration scale, to a density of greater than 1.5 (a very high level) at the higher end of the antibody concentration scale.

Each analytical value will be accompanied by a basic interpretation as to whether levels are considered low, medium or high. It is not yet known exactly how long people will maintain their levels of antibodies, but this will depend on individual differences and may be affected by many factors such as age, whether you are male or female, diet, and general health and fitness. Further research and testing will help scientists discover more about how long immunity to Covid-19 is likely to last.

High Typically, individuals with high levels of antibodies:

  • have received both vaccinations OR
  • have received both vaccinations and have had a COVID-19 infection
Medium Typically, individuals with medium levels of antibodies:

  • have received one or both vaccinations OR
  • have had a COVID-19 infection OR
  • have had one or both vaccinations and have had a COVID-19 infection
Low Typically, individuals with low levels of antibodies:

  • have received a vaccination recently OR
  • have received both vaccinations several months ago OR
  • have previously had a COVID-19 infection and no vaccinations
Not
Detected		 Typically, individuals with no antibodies:

  • have not had COVID-19 or any vaccinations
  • have had vaccinations that have not been successful

If you wish to track your levels of Covid-19-specific antibodies, it is advisable to test your blood every 1-2 months to monitor any decline in antibody levels.

Please ensure you wait at least 14 days after receiving a dose of a Covid-19 vaccination or after testing positive from a confirmed Covid-19 infection before taking the test.

All testing is carried out in our award-winning UK laboratory

Frequently Asked Questions

Does the detection of antibodies mean that I am immune to Covid-19?

No, the detection of antibodies does not mean that you are immune to Covid-19 and does not mean that you cannot be infected. However, the presence of antibodies within a sample demonstrates that your body has staged an immune response to the virus (either as a result of a previous infection or Covid-19 vaccination). It means that you should have some protection against a serious infection and should be less infectious towards others.

What will the results tell me?

Your report will provide a quantitative result that relates to the level of Covid-19 antibodies within your sample and whether the level is low, medium, high or not detected. The presence of antibodies provides assurance that your vaccine has been successful, or that you have had a previous Covid-19 infection. Testing can be used to track antibody levels over time. It can help determine whether you require a booster or can be used as proof of having Covid-19-specific antibodies for certain situations (e.g. admission to events).

Example antibody report

Will this test tell me if my vaccine has worked?

If you haven’t had a Covid-19 infection, then the presence of antibodies indicates that the vaccine has been successful and that your body has staged an immune response against the virus.

The test should be taken at least 14 days after vaccination.  

How long should I wait to do this test after having a Covid-19 vaccination or after testing positive for Covid-19?

We would advise waiting at least 14 days after receiving a dose of a Covid-19 vaccination or after testing positive from a confirmed Covid-19 infection before taking the test.

Can these tests be used as evidence of having Covid-19-specific antibodies for international travel?

Some countries accept laboratory-based antibody reports as evidence of having Covid-19-specific antibodies for international travel. Please check the guidelines of the country you are travelling to in order to establish whether this test would be suitable or acceptable.

What is in the antibody test kit?

The kit contains everything you need to collect your sample and return it to our lab. This includes an instruction sheet, an alcohol wipe, two blood lancets (including one spare, in case required), a blood sample collection card, and a pre-paid tracked envelope to return your sample free of charge.

How do I send my sample back to the lab?

Once you have collected your blood sample, follow the instructions provided and post it back to our laboratory using the Royal Mail pre-paid tracked envelope contained in the kit.

How do I get my results?

You will receive your results within 3 working days of your sample being received at our laboratory. Please note that results are available Monday to Friday, with our laboratory closed on weekends.

You results will be sent by email using the email address provided when registering your sample online.

Will the results be affected by the flu vaccine?

The assay is specific for SARS-CoV-2 antibodies so the flu vaccine won’t affect the result.
