Covid-19 Antibody Testing

Our previous antibody test (CIMA Assay Abbott SARS-CoV-2 IgG) provided a “positive” or “negative” result. As of 1st September 2021, we are now able to offer the new, advanced quantitative Covid-19 antibody test (Roche Elecsys Anti-SARS-CoV-2 S (Spike)) which will actually provide a numerical result giving you the level of Covid-19 specific antibodies in your blood. 

We can now answer the question of “how much?”, which means it gives an answer about the body’s immune response to the virus – either from previous Covid-19 infection or after a vaccination. 

Find out the strength of your antibody response either to previous Covid-19 infection or after having had the Covid-19 vaccine

FAQs

What is the NEW quantitative Covid-19 antibody test and how is it different from the previous lab antibody test (Abbott)?

The main difference between the Quantitative Antibody Test and the Abbott Antibody Test is that with this newly released Quantitative Test we can not only know that our bodies have developed an immune defence to COVID-19, but now we also will be able to measure how high our antibody count is. This test will allow you to monitor your antibody count and immune response following infection or vaccination.

The test is very accurate with a specificity of 98.8% and sensitivity of 99.8%.

Advantages of the NEW quantitative antibody test?

It will specify the level of antibodies in your blood. This in turn informs you on the level of your immune response to the virus or the vaccine.

  • A positive antibody test result has been shown to protect against COVID-19 for at least 6 months. Therefore, by taking this test, it can help to find out if you have short-term future immunity to COVID-19.
  • Because the test gives a numerical value specifying the level of antibodies in your blood, it gives a baseline for any future antibody testing you may decide to have.
  • If you have a high level of antibodies from the test you also will have a high level of neutralising activity i.e. the ability to stop a live virus from entering and infecting blood cells.
How can the Quantitative Antibody Testing detect antibodies developed after COVID-19 Vaccine?

Quantitative Antibody testing uses the spike protein, which is the target of many COVID-19 vaccines, while the Abbott Antibody Test uses Nucleocapsid protein which only detects IgG developed after an infection.

What is the Rapid Antibody Test?

This Rapid antibody test will not detect neutralising antibodies produced by vaccine injection, as vaccines normally use S Proteins while this mainly uses the N Protein for detection.

When should I have my spike protein antibody test?

Testing should be undertaken 14 days or more following exposure,  onset of symptoms or post-vaccination. The incubation period of Covid-19 ranges from between 1 to 14 days, with the majority of cases manifesting with symptoms at 3–5 days. 

Interpreting your spike protein IgM / IgG antibody results

Antibody testing can detect whether a person has been infected previously or has a vaccine-induced immune response. Our new Roche Elecsys Anti-SARS-CoV-2 S (Spike) IgG/IgM Total Antibody test blood test enables the determination of both the presence and level of antibodies to the SARS-CoV-2 spike protein, which is the target of many COVID-19 vaccines. It can signal whether a person has already been infected and has potentially developed immunity to the virus, and plays an important part in characterising a vaccine-induced immune response.

Your laboratory results will be reported as a reference range: 

>/= 0.80 U/mL: This is a positive result for anti-SARS CoV-2S. A positive result means your body’s immune system has generated a response to the COVID-19 vaccine. It may also mean your body’s immune system has generated a response to a prior COVID-19 infection. The test is not able to differentiate whether the antibodies produced were in response to the vaccine or to a prior infection. 

< 0.80 U/mL: This is a negative result for anti SARS CoV-2S. A negative result means your immune system has not generated a measurable response to the COVID-19 vaccination and that you have likely not had the COVID-19 infection. 

Please note: A numerical value will be reported up to 2,500 U/mL. For patients testing higher then 2,500 U/mL, your results will be reported as “Greater Than 2,500 U/mL.”

It is yet undetermined what Antibody level is correlated to immunity against developing the COVID-19 infection.

 

How do I find out my test results?

We will email your results and a detailed explanation the day after your appointment. Please check your junk/spam folders before contacting us regarding your results.

For the Covid-19 Rapid In-Clinic Antibody Test your results will be immediate and given to you after your test.

If I have Covid-19 antibodies, does it make me immune?

Needed a RT-PCR Covid -19 Test and lab results, along with a Fit-to-Fly certificate at the last minute. Spoke with one of the Clinic Partners, Practice Manager, Reception and of course the Doctor - throughout the whole process from start to finish. Everyone was fantastic, knew the answers and gave me the assurances I needed. Having already spoken to several other clinics, it was clear Whitehall were at the top of their game. Truly excellent throughout, would highly recommend and thank you once again.

We booked our COVID test to obtain a fly safe certificate. We arrived a few minutes before the appointment and were seen at our appointment time. The doctor who performed the test was very reassuring and confident. I received my results back 25 hours after the test, however there was a bit of stress as my husband didn't get his for another 3 hours after me. However we both got our results back in plenty of time to get the fly safe certificate and we are now very much looking forward to our holiday
