COVID-19 Coronavirus Rapid Test

Finger-prick antibody test

COVID-19 Coronavirus Rapid Antibody Test (SureScreen Test Cassette)


Due to demand from some of our regular clients we have available COVID-19 antibody tests by SureScreen Diagnostics.

This is NOT a test to check if you are COVID-19 positive or negative. Please do not come in if you are displaying any COVID-19 symptoms. Please only consider having this test if there is a genuine reason to do so.

SureScreen diagnostics COVID-19 rapid antibody test identifies the body’s response to coronavirus after the onset of infection, and gives a qualitative yes/no result within 10 minutes. This finger-prick antibody blood test detects two types of antibodies- IgG (past infection more than 7 days) and IgM (recent infection 3-7 days). The test is carried out by registered Nurse.

About Coronavirus (COVID-19)

COVID-19 is an infectious disease that can affect your airways and lungs, caused by the most recently discovered coronavirus.

This infectious disease was unknown until the recent outbreak which originated in China in late 2019. At time of writing, cases of COVID-19 continue to rise daily across the globe.

The most common symptoms associated with COVID-19 are fever, tiredness and a dry cough, loss of taste and or smell. There may be other symptoms not listed here but symptoms can take up to 14 days to appear so it is difficult to know if someone has been infected ahead of these conditions appearing. In the meantime, infected people can spread the virus unknowingly.

Implementing rapid screening for COVID-19 has huge time and cost savings when compared to laboratory screening and will help to control the spread of the virus by identifying infection rapidly.

Our test results at Towcester Clinic are not used as part of survey/research.

Throughout the country there are national surveys/researches being carried out with finger-prick blood antibody tests to help the Government understand how many people have been infected with the Virus which causes COVID-19.

If you receive a positive antibody result it does not mean that you are immune, or that you cannot pass on the virus to others. It also does not mean that you can ignore social distance measures. Please follow Government guidelines.

Understanding of the body’s immune response to COVID-19 is still limited. How long an antibody response lasts and whether the produced antibodies are effective in neutralising the virus or whether having antibodies means a person cannot transmit the virus to others is not known.



Has the test been accredited?

Surescreen COVID-19 test is CE marked for professional use only and is therefore a registered IVD device.

Manufactured in UK.

What are IgG and IgM?

Immunoglobulins are antibodies themselves and are part of our immune system. When we get an infection, such as COVID-19, immunoglobulins are produced, which attach to the virus and activate the rest of the immune system to attack and clear the virus.

IgM is the first immunoglobulin to be produced. The presence of IgM is an indicator of early infection (usually 3-7 days)

The presence of IgG is an indicator of later stage infection (usually 7 days or longer after infection).

So can the test detect asymptomatic patients?

Yes, the test will be able to detect IgM/IgG in asymptomatic people, as they will have an immune response even though they don’t display symptoms. The timeline of infection will be the same as someone displaying symptoms.

When will I get the results?

For the result, the window of accuracy is 10-15 minutes

Do any medications, drugs or other proteins in the blood affect the test result?

To date numerous common pharmaceuticals have been tested and none of which have interfered with the test, hence currently no cross-reactivity issues are of concern. More drugs are being looked at and will be updated accordingly.

How accurate is the test?

Number of studies have been conducted with:

  • Kings College London
  • Guy’s and St. Thomas’s London
  • UZ Leuven Belgium
  • The French National Centre for Scientific Research
  • Cambridge University
  • Imperial College London
  • Many more

One such example is the independent evaluation conducted by Guy’s and St. Thomas NHS, London. 503 samples were tested and the test obtained the following results:

  • Sensitivity: 96.55%
  • Specificity: 99.67%
  • 98% accurate

Several clinical studies are evidence of the usability and effectiveness of the test. In addition to clinical evaluations already completed on the product, number of independent laboratories and Departments of Health across Europe are currently working to further validate the product and gain best practice approvals.One such example is the independent evaluation conducted by Guy’s and St. Thomas NHS, London. 503 samples were tested and the test obtained the following results:

Will IgG and IgM remain in the blood after I’ve recovered from COVID-19?

There is some evidence that IgG/IgM remains in the blood after recovery to prevent reinfection. Some patients and noticed that they still test positive for at least 33 days after first displaying symptoms. You won’t be infectious after you recover, even if you test positive, but you should still be cautious as long term immunity has not yet been confirmed and reinfection may still occur.

Does it hurt?

Yes it does a bit. It is similar to the diabetic fingerpick blood test. We use good quality lancets to get the best results.

Can babies and young children be tested?

Yes, there are no issues with testing babies and young children.

Can pregnant or breast feeding women be tested?

Yes, there is no harm to the mother or baby when performing a test.

Is there anyone that shouldn’t be tested?

No, the more people that are tested, the better it will be to understand the spread of the virus, which will result in better measures being taken to prevent its spread. However, as the test requires a blood sample, anyone with a blood-related health condition (such as haemophilia) should discuss this with a healthcare professional before performing a test.
