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
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.
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.
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.
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.
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.
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.

Very accommodating regarding times. Arrived early but only waited 3 minutes before being shown in. Dr. Khan managed to be both efficient and proficient at the same time as being very convivial. He was also very informative and helpful.
My covid testing for international travel was hassle free at Whitehall! Got my results in less than 24 hours. Clinic is easily accessible from the train station and top notch service.
Really fantastic service here. I can’t recommend them enough. Staff were brilliant. Test results took less than 24 hours.
Amazing turnaround times! Literally dropped in 24 hours ago for a swab test (PCR) and received my results along with a fit to fly test the next day! Fantastic service.
The team gave us a lot of assistance and on the day the reporting and testing was done very professionally. I can definitely recommend Whitehall Clinic.
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.
Absolutely a first class experience. Brilliant communication and customer service. Took all the drama out of Fit to Fly requirements. Exceeded their promise and timescales. Highly recommend and thank you.
Straight forward online booking system. Central leeds, easy to find with nearby parking. Really friendly & helpful staff. Very professional set up. Results emailed within 24hrs. Couldn’t recommend Whitehall clinic enough.
Went for a COVID-19 antibody test. Excellent experience. Seen on time, test done efficiently and results received the next day as promised. Highly recommended.
Excellent Customer Services. Professional & State of the Art Medical Clinic with Amazing Turnround Times - Good Job Thank You.
Quick, efficient and a most brilliant and helpful and kind lady on the phone. More expensive than other some tests, but your receptionist is wonderful. It is so reassuring to speak to a human being.... plus I was sent my results in under 24 hours.
The premises are excellent. The test was performed on time and the results were received by email the next day.
Excellent service from start to finish. Very flexible times for appointment had my Covid test on Wednesday evening at 6pm got my results 10pm Thursday. Very impressed. All staff were welcoming very professional and Efficient would highly recommend.
Excellent service from making the appointment to attending. Results were emailed to me the same day. The staff were efficient and friendly and Dr Khan was extremely helpful in advising us of the correct test we needed. After hearing about other test centres that failed to submit the tests on time I would not hesitate to recommend this clinic.
I had my whole wedding party of 20+ come here for our pcr test and fit to fly certificate for Cyprus September 2020. I can not recommend them enough, they were absolutely fantastic very efficient very helpful and we will be certainly using them again in the future. Thank you so much 😊
Whitehall Clinic is professional, efficient, personal and friendly. The treatment provided for myself and my wife was nothing short of excellent and we are extremely grateful to the chief medical director for his selfless dedication to our problems. There was a happy outcome for us only because of his efforts, over and beyond the call of duty.
During the test, the doctor explained the process well and did it efficiently and was very kind as I was nervous. Really good experience.
I have received one of the best customer service ever. Great team that understand your circumstans and they will try to help you as much as they can. 5 star service even on the weekends. I highly recommend this clinic.
Fantastic service, I was early and they saw me right away, everyone was very friendly and efficient. I had a covid pcr test, it was quick and easy and I got my results back literally after midnight that same day and considering I got my test done on a Sunday that's pretty impressive. Can't recommend them enough. Thanks so much.
The medic was very professional and caring and the test was carried out relatively painlessly and I had my results back within 23 hours. Very good service and i would recommend
A thoroughly professional and friendly clinic. Everything felt right about it. And test results which were promised within 48 hours came through in 7 hours. I would definitely use Whitehall clinic again.
This clinic is definitely five star service my husband travels a great deal with his work and has had many PCR tests. This clinic is absolutely the best professional the staff are friendly informative and the test is done by a professional I would highly recommend this clinic 100% my husband has nothing but praise for them.
Brilliant service, super easy and friendly. Got my PCR test done and got my results after exactly 24 hours. It might be slightly on the expensive side, but it's definitely worth it. Would recommend 👌
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
