What does the antibody laboratory test measure?

The SARS-CoV-2 antibody laboratory test measures the presence of IgG antibodies to COVID-19.

Why are antibody tests important?

Not everyone infected with the coronavirus develops symptoms so severe that they see a doctor. And not everyone is tested. Do you want to know if you have already been infected with Corona?

If you have already been infected with the SARS-CoV-2 coronavirus, you have so-called IgG antibodies in you. These antibodies can be detected in the blood. In this way, you will receive an indication of whether you have already had COVID-19 behind you and are therefore probably immune to further infection (100% scientific statements on this are not yet available, but it is assumed).

Researchers find it difficult to estimate how many people actually got the disease. An antibody test can be used to determine a rough number of unreported cases and thus better track the spread of the virus. This can be an important factor in deciding whether contact restrictions and other measures can be relaxed.

Warning there are two different antibodies that can be tested - namely IgG (indicate a past COVID-19) and IgM (indicate an acute infection). At the moment only IgG tests provide valid results.

Who should do the SARS-CoV-2 antibody laboratory test?

The antibody test is useful for all people who want to check whether they have already contracted COVID-19. In some cases, the novel coronavirus causes only mild flu-like symptoms or even no discomfort at all. Because of this, many people are not sure that they might not already have the virus in them.

The antibodies are detectable from one to two weeks after the onset of the disease. As a rule of thumb, it can be said that the test makes sense from around 14 days after flu-like symptoms have appeared or you suspect that you may have been ill. IgG antibodies can be detected in the blood for several months.

If you are currently experiencing the symptoms of a flu or a cold, the antibody test is probably not worthwhile - the antibodies cannot always be detected in the early stages of the disease. If you want to find out whether you have an acute infection, a PCR test, which detects the genetic makeup of the virus in a DNA sample (saliva), makes more sense.

How does the SARS-CoV-2 antibody laboratory test work?

The kiweno SARS-CoV-2 antibody laboratory test is a test kit for at home using the Dried Blood Spot method. The Dried Blood Spot method is an innovative blood collection method using blood filter paper. We only need a few drops of blood, which are then analyzed and evaluated in the laboratory. You will receive the result by email. You can take the test anywhere - without any prior medical knowledge.

The laboratory uses the established ELISA measurement method to detect the IgG antibodies in your blood that the body produces against the coronavirus. The accuracy of our laboratory test is 100% sensitivity and 99.1% specificity.

How meaningful is the SARS-CoV-2 antibody laboratory test?

The kiweno SARS-CoV-2 antibody laboratory test uses the scientifically established measuring method for antibody analysis in COVID-19, namely the ELISA test method. It is currently the most informative method to determine whether you have already had the coronavirus in your body.

Like most medical tests, it is not 100 percent accurate. The accuracy of our laboratory test is 100% sensitivity and 99.1% specificity. In rare cases, false positive results (you tested positive but not yet had the virus) or false negative results (you tested negative but already had the virus).

The accuracy of laboratory tests such as the kiweno SARS-CoV-2 antibody laboratory test, however, is subject to precise control and the ELISA method used in this test is considered to be one of the most precise methods in laboratory diagnostics.

What does the result of the SARS-CoV-2 antibody laboratory test tell me?

The test result of the antibody test tells you whether you have already been infected with the coronavirus or not. Positive means that IgG antibodies against SARS-CoV-2 have been measured in your blood. Negative means that it did not. In the case of an infection that has already subsided, it is not yet 100% clear at the moment whether an immunization is present or not. This is still being researched.

If pathogens such as viruses get into your body, your immune system works under high pressure to fight them. Among other things, antibodies are produced in the process.

These antibodies are aimed at very specific pathogens. Specific antibodies recognize a certain virus or bacterium, bind to the pathogen and allow the immune cells to attack it.

Once your immune system has made the antibodies, they stay in the body for a long time. How long depends on the class of antibodies. The IgG antibodies, for example, are still active in fighting viruses for years in some cases. As long as they are in the body, they can neutralize the same virus if they encounter it again. If this is the case, you are practically immune to the pathogen - one speaks of an immunization / immunity.

Am I immune to a positive result?

At the moment it is not yet 100% scientifically proven that you are really immune to re-infection after being infected with the coronavirus. But initial studies on humans and monkeys make the researchers optimistic that most people will build up immunity after surviving COVID-19.

Other studies and media reports from China and South Korea suggest that people there had been infected with the virus several times or that the virus had become active a second time. According to some virologists, this could be due to the measurement methods that deliver negative results at certain measurement times even though the virus is still in the body.

What do SARS-CoV-2 and COVID-19 mean?

SARS-CoV-2 is the scientific name for the novel coronavirus. The abbreviation stands for Severe Acute Respiratory Syndrome Coronavirus 2.

COVID-19 in turn stands for the disease that causes the virus. It is the abbreviation for Coronavirus-Disease-2019, i.e. Coronavirus-Disease-2019. The year refers to the first outbreak of the disease in China in December 2019.
The disease COVID-19 can get people of all ages. It is less common in children under the age of 15, but has also occurred in infants. Severe and potentially dangerous processes primarily affect older people and people with previous illnesses (e.g. cancer, cardiovascular diseases, diabetes, lung diseases, asthma).

What are symptoms of COVID-19?

Around 80 percent of those affected have mild or moderate courses. In this case, among other things (mostly dry) cough, fever and sometimes runny nose, up to mild pneumonia.
Some people affected do not feel any symptoms at all, but are still contagious, they have so-called silent infections.
Meanwhile, studies also indicate that the loss of smell and taste can be a sign of the coronavirus.
If the course is severe, it can lead to severe pneumonia with difficulty breathing and shortness of breath up to life-threatening lung and organ failure.

According to the Robert Koch Institute, other symptoms that are less common but have also been reported include:

  • Sore throat as well as headache and body aches
  • Loss of appetite and weight loss
  • Rashes
  • Nausea, abdominal pain, vomiting, and diarrhea
  • Conjunctivitis
For whom is the SARS-CoV-2 antibody laboratory test not suitable?

The SARS-CoV-2 antibody laboratory test is unsuitable or only suitable to a limited extent for certain groups of people:

  • People with infectious diseases such as hepatitis and HIV are not allowed to take the coronavirus antibody test.
  • People with hemophilia should not do the blood test.
  • Pregnant and breastfeeding women should only carry out the coronavirus antibody test under medical supervision. The reference values ​​and recommendations do not apply to you either, so you should obtain recommendations on the test results from your doctor or therapist.
  • The coronavirus antibody test is not suitable for children under 18 years of age.

  • Important: The test is not intended to diagnose an acute infection with the coronavirus. If you have the flu symptoms, call your doctor or health department.
    What does sensitivity and specificity mean?

    Sensitivity and specificity are statistical measures. They help assess binary classification tests (tests with only 2 possible outcomes).

    sensitivity measures the proportion of actual positives that are correctly recognized as such (e.g. the percentage of sick people who are correctly recognized as such).

    Specificity measures the proportion of actual negatives that are correctly identified as such (e.g. the proportion of healthy people who are correctly identified as not sick).
