COVID-19 Antibody Testing

Covid 19
  • fast and accurate 
  • results in 15 minutes
  • CE approved gives you peace of mind


The Otto Clinic now provides Covid-19 Antibody Testing to anyone who may be concerned they have been exposed to Coronavirus (also known as IgG Antibody Testing for SARS-Cov-2).  Fast, accurate and reliable, our blood test is performed here in our Limerick clinic and will determine whether you have had SARS-CoV-2, the virus that causes coronavirus disease 2019 (COVID-19).  The fast turnaround – results are available in 15 minutes – avoids the worry and stress of waiting for results.

Please note:

  1. After infection, it takes two to three weeks to develop enough antibodies to be detected in an antibody test – the antibody test should be carried out 14 days or more post symptoms of Covid-19 for greatest accuracy

  2. An antibody test will not identify whether you are currently infected with the COVID-19 virus.

What is the COVID Antibody Blood Test?

This is a rapid test designed to detect IgG antibodies produced by the immune system as a response to the Coronavirus infection.  A positive test result indicates that antibodies were produced in response to a SARS-CoV-2 infection.

Antibodies are proteins produced by your immune system in response to an infection and are very specific to the invading microorganism.  Antibodies can be detected in your blood for several weeks after the infection has occurred.  However, as COVID-19 is a new virus, scientists do not yet know how long the antibody response lasts or how effective it is at neutralising the virus.

The Blood Test Procedure

When you come to the clinic, one of our nurses will take a 10ml blood sample from your arm.  This sample is run through our specialised testing equipment in-clinic which displays the result in approximately 15 minutes.

Remember, the test is only accurate if it is carried out 14 days or more after you have had the infection. 

Your blood test results:

  • Positive: A positive test means you have COVID-19 antibodies in your blood, which indicates past infection with the virus. It's possible to have a positive test result even if you never had any symptoms of COVID-19. False-positive test results can occur. It may be that the test detected antibodies to a coronavirus closely related to the COVID-19 virus or that the test quality was flawed.

  • Negative: A negative test means that you have no COVID-19 antibodies, so you probably were not infected with the COVID-19 virus in the past.  It may also mean that you have been infected but had a mild case and therefore the level of antibodies in your blood cannot be detected.  Because it takes time for antibodies to develop, false-negative test results can happen if the blood sample is collected too soon after your infection started.

People who have had COVID-19 or tested positive for antibodies should not assume they are immune to coronavirus or that they will not infect someone else.

Disclaimer - Some Further Points To Note:
  1. the presence of antibodies does not necessarily mean that the individual is protected against furture attacks of COVID-19

  2. it is also important to note that as COVID-19 is a new disease, we do not know how long the antibody response lasts or whether the antibodies are effective at neutralising the virus


COVID-19 Antibody Test: FAQs

What Do The Results Mean?

Positive: A positive result indicates past infection with the virus. It is possible to get a positive result even if you never had symptoms. A false positive result is also possible - this may occur if the test detects antibodies to a coronavirus closely related to COVID-19 or the test quality is flawed. Negative: a negative result means there are no COVID antibodies present which can mean either that you probably have not had Coronavirus or that you had such a mild case that the test is unable to detect the presence of antibodies in your blood.

When Should I Get The COVID Antibody Test Done?

Coronavirus antibodies can usually take 8-10 days to appear but, occasionally, this can take longer. To ensure your body has had sufficient time to create the antibodies, and to avoid a false negative result, it is recommended that this test should be done 14 or more days after you started to become sick.

How Accurate is The Antibody Test?

This test is highly accurate with 99.6% specificity and a sensitivity of 100% at 14 days after symptoms started rising to 99.9% specificity and sensitivity of 100% after 17 days of onset of symptoms.

The test is also CE approved meaning that it meets EU standards for health, safety and environmental protection.

What is the COVID-19 Antibody Test?

The COVID-19/Coronavirus Antibody test is a blood test during which a nurse will take a 10ml sample of your blood. This sample is run through specialised testing equipment and will determine whether you have COVID-19 antibodies in your blood.

How Does The COVID-19 Antibody Test Differ From The Viral Test?

The Antibody test offered by The Otto Clinic identifies if you have had Coronavirus in the past by detecting COVID-19 specific antibodies in your blood. It is a post-infection blood test and will not tell you if you currently have the virus.

The Viral test is a nose and throat swab test that checks respiratory symptoms by taking swabs from your nose and the back of your throat to screen for current, active infection. This determines whether you currently have the virus.

How Long Does The Test Take & When Can I Get Results?

The entire procedure from start to finish takes approximately 15 minutes and you will get your test results immediately from the nurse.

How Much Does The Test Cost?

The cost for this in-clinic test is €80.
