Information about the antibody test
Note: The result is basically a snapshot at the time of sampling.
Taking a blood sample
With one of the lancettes included with the Coronavirus Antibody Test, take a few drops of blood and collect them in the tube.
Our recommendation: Take the sample at the earliest 14 to 21 days after you have had suspicious symptoms. From this point on, the antibody analysis is usually most meaningful.
Activate antibody test
Enter the test ID listed on the test ID card in your secure My cerascreen user account on our website or on our app. You will then need to answer a short survey about your health conditions and symptoms.
Send blood sample
Send the collection tube with the blood sample by post to our partner laboratory free of charge using the prepaid return envelope.
In one of our medical laboratories within our network of partner labs, your sample will be tested for specific IgG antibodies against the SARS-CoV-2 virus.
The results report will tell you if your sample tested positive or negative, or whether or not you were possibly already infected with coronavirus and could now be immune.
High quality standards
Laboratory cerascreen tests® are analysed in a specialised meidcal laboratory. All of our lab partners meet our high quality and safety standards.
Advantages of the Coronavirus Antibody Test
The sample can be taken safely and discreetly at home. During the pandemic, there is no need to leave your home or visit a doctor. In this way you protect others and do not impose a risk of infection on medical professionals.
The cerascreen® Coronavirus Antibody Test is analysed by a medical laboratory and uses the same method that is used to research the coronavirus. The more antibody tests that are done, the better the status of the pandemic can be evaluated.
Take advantage of our expertise: cerascreen® is the market leader for at-home medical sample taking and send-in kits in Europe, with 8 years of experience in the developement and analysis of tests. We have developed more than 50 different approved sample taking and send-in kits (medical products) , analysed 250,000 samples, and serve 19 different european countries.
ELISA analysis for IgG antibodies in the medical lab
Why test only for IgG antibodies?
The cerascreen® Coronavirus Antibody Test uses the most diagnostically conclusive measurement of persistent IgG antibodies. With this antibody analysis, it can be determined if a recent SARS-CoV-2 infection has occurred but also one that has occurred a few weeks back.
Lab test with ELISA method vs. Rapid test
The greatest possible test accuracy of the antibody test is paramount! The higher the measurement specificity, the higher the likelihood of a correct test result.
The cerascreen® Coronavirus Antibody Test is based on the approved ELISA method.
This established method is highly accurate and is conducted in a medical lab by specialised professionals. Experts therefore consider these tests to be diagnostically more relevant than rapid tests, which give you a result at home immediately.
The results report
As soon as your sample has been analysed, you will receive a notification via themy cerascreen®-App or your user account on our website for your test result. You can view your results on your smartphone, tablet, or computer; you can also print it out.
Discover according to the lab analysis, if your blood sample tested positive or negative for IgG antibodies to SARS-CoV-2. With the help of our recommendations, find out what to do in case of a postivie or negative test result. We also provide further information about the COVID-19 pandemic.
Questions about the Antibody Test
Why are antibody tests important?
Not everyone who has been infected with coronavirus had symptoms and went to the doctor. And not everyone has been tested. So it is difficult for researchers to estimate how many people were actually sick and how many have been infected. An antibody test allows for a rough estimate of unknown cases and thus a better monitoring of the spread of the virus. This is an important factor for deciding whether contact limitations and other measures can be relaxed.
How do antibody tests help? If you have been infected with coronavirus SARS-CoV-2 you probably carry the antibodies. These antibodies can be detected in blood by laboratories. This will indicate if you have already been infected with COVID-19 and are therefore likely immune to a further infection.
Who should take the test?
The Antibody Test is helpful for people who want to check if they have already been infected with COVID-19. In some cases the novel coronavirus causes mild flu-like symptoms or even no symptoms whatsoever. This is why many people are unsure whether they may have already had the virus.
The antibodies can be detected one to two weeks after the beginning of the disease. A good rule of thumb is that the test is useful starting at around14 days, after you have had flu-like symptoms.
If you currently have symptoms of a flu or cold, then a test is probably not useful –antibodies cannot always be detected in the earlier stages. If you want to test if you are currently infected, you need a PCR test like the cerascreen® Coronavirus Test to detect the presence of the genetic material of the virus (currently only available in Germany).
How does the test work?
The cerascreen® Antibody Test is a sample taking and send-in kit for home use. It uses a small blood sample taken from a fingertip –take it where and when is convenient for you. Then simply send the sample tube to our diagnostic laboratory.
The laboratory uses the established ELISA analysis method in order to test your blood for IgG antibodies to the coronavirus. When the analysis is complete, you will receive a notification by email or the my cerascreen® app. You can then download your personal results report with your test result.
How conclusive is the test?
The cerascreen® Antibody Test uses scientifically established measurement techniques for the detection of COVID-19 antibodies. It is a very diagnostically conclusive method for determining if a coronavirus was present.
Just as all medical tests, it is not 100% accurate. In rare cases it can lead to a false positive (you tested positive, but have not yet had the virus) or a false negative (you tested negative, but have already had the virus).
The accuracy of laboratory tests like the cerascreen® Antibody Test is, however, considerably higher than quick tests that give a result without having been analysed in a lab.
What does the result tell me?
The results report will tell you if your result was positive or negative. Positive means that antibodies to SARS-CoV-2 were detected in your blood. Negative means they were not detected.
A positive result can be an indication that you have already had a coronavirus infection.
What is the ELISA analysis method?
ELISA stands for “Enzyme-linked Immunosorbent Assay”. It is the standard scientific method that labs use to detect antibodies in the blood. ELISA is typically used for allergy tests or to diagnose infectious diseases, and is also the established laboratory measure for antibody tests for SARS-CoV-2.
The virus (the antigen) is attached to a special lab plate, to which your sample is then added. If there are antibodies in your sample, then afer a while they bind to the antigens to form complexes.
Then a special enzyme, which is likewise bound to an antibody, is added. If there are antibody-antigen complexes on the plate, then the newly formed enzyme-antibody bundles will dock on them.This larger complex is then called the “ELISA sandwich”.
If these “sandwiches” are present, then a chemical substance added to the enzyme will as a result change color. The color intensity indicates if there are antibodies in the sample and if so, how many.
Do I need to report my result?
No. In contrast with a result from a PCR Test, one is not required to report the antibody test result. Neither you nor the lab is required to report the result to the public health office.
There are still no special regulations currently for people with a positive antibody test result. Even if one is possibly immune, the contact restrictions still apply.
What does immunisation mean?
When pathogens like a virus enter the body, the immune system is on full alert to fight them. In this process, antibodies are created.
Antibodies are designed for certain pathogens. The specified antibodies recognise the virus or bacteria and bind to it, which allows the defense cells to attack it. If, together with other tools of the immune system, they ensure that the pathogens cannot trigger the disease again, this is called immunity.
If your body has produced these antibodies at any time, they remain in the body. How long that is for depends on the class of antibody. IgG antibodies for instance can remain active to fight viruses for years in some cases.
Does a positive result mean I am immune?
It is currently not yet scientifically confirmed if one becomes immune after a coronavirus infection. However researchers are optimistic after early studies with humans and monkeys show that most people build an immunity after recovering from a COVID-19 infection.
Other studies from China and South Korea have suggested that people there have been infected with the virus multiple times or that the virus was reactivated. According to some virologists, this could be due to the measurement method, which can result at certain times in a negative result even though the virus is still present in the body.
Is there a coronavirus hotline?
For urgent questions about coronavirus, phone your GP and they will assess you over the phone or contact HSELive on 1850 241 850
In case of emergency such as difficulty breathing, dial the emergency number 112 or 999.
What do SARS-CoV-2 and COVID-19 mean?
SARS-CoV-2is the scientific denomination for the novel coronavirus. The abbreviation stands for Severe Acute Respiratory Syndrome Coronavirus 2.
COVID-19 on the other hand, stands for the illness that the virus causes. It is the shorthand for Coronavirus-Disease-2019. The year represents the first outbreak of the disease in China in December 2019.
People of all ages are susceptible to COVID-19. Children under 15 years of age are less often affected, but some infants have already been infected.
Difficult and potentially dangerous infections happen primarily in older people and people with pre-existing conditions (e.g. cancer, heart disease, diabetes, respiratory conditions, asthma), as well as smokers in some cases.
What are the symptoms?
Data from China where the first virus outbreak occured show for around 80 procent of cases, people experienced mild or moderate symptoms. For these cases, that meant a (typically dry) cough, fever, and sometimes a head cold, or even a mild pneumonia.
Some patients experience absolutely no symptoms, but are still contagious; they are so-called carriers.
In the meantime, studies suggest that the loss of the senses of smell and taste can be a sign of the coronavirus.
Severe cases range from acute pneumonia with difficulty breathing and respiratory distress to life-threatening lung and organ failure.
According to the HSE further symptoms that are less common but have been reported include: - Fever or chills
- Loss of appetite and weight loss
- Aches and pains
Who is the test not intended for?
The Coronavirus Antibody Test is not intended for the following groups of people:
- People with infectious diseases like hepatitis and HIV may not use the Coronavirus Antibody Test.
- People with haemophilia should not take the test.
- Pregnant and nursing women should only take the Coronavirus Antibody Test under medical supervision.The given reference ranges and recommendations do not apply for people in this group; consult your medical professional for advice concerning your test result.
- The Coronavirus Antibody Test is not intended for children under 18 years of age.
- The Test is not meant to diagnose an acute infection of the Coronavirus. If you have flu symptoms, contact your doctor or the local health office. Current symptoms can be followed up with a PCR test such as the cerascreen® Coronavirus Test (currently only available in Germany).
