COVID-19 test

The demand for a reliable COVID-19 test is increasing. Not only to find out if you are currently infected, but also if you have been infected previously. In the latter case, How Are You Diagnostics can help. We offer a self-sampling test for COVID-19 antibodies. With this test, you take a blood sample yourself, after which our laboratory examines whether antibodies for COVID-19 are present. This enables you to find out – anonymously and quickly – whether you have ever been infected with the virus.

Please note: are you currently experiencing one or more symptoms of the novel coronavirus? Then do not order our self-sampling test for COVID-19, but call 0800-1202 directly. In that case, you can schedule an appointment for another (rtPCR) COVID-19 test at the GGD.

The symptoms of the novel coronavirus

The symptoms of COVID-19 can vary from person to person. While some patients experience no symptoms, others end up in the ICU and may die from the infection. A common question is therefore: have I had COVID-19? A COVID-19 test is recommended if any of the symptoms listed below are or have been present.

Please note: are you currently experiencing one or more symptoms of the novel coronavirus? Then do not order our self-sampling test for COVID-19, but call 0800-1202 directly. In that case, you can schedule an appointment for another (rtPCR) COVID-19 test at the GGD.

Common symptoms

The exact symptoms experienced by a patient with COVID-19 vary from person to person. It can be difficult to determine whether you should have a COVID-19 test. We recommend that you always get tested for COVID-19 when you recognise any of the following symptoms in yourself:

  • Cold symptoms such as rhinitis, runny nose, sneezing,
  • Sore throat
  • Cough
  • Shortness of breath
  • A high temperature or fever
  • Sudden loss of smell and/or taste (without nasal congestion)


Serious complaints

Are you suffering from shortness of breath and/or fever (above 38°C) or are you feeling increasingly ill? Contact the GP or the GP out-of-hours surgery immediately.
f you are currently experiencing symptoms of COVID-19, we recommend that you take a PCR COVID-19 test. Make an appointment now by clicking here.

 

How can I get tested for COVID-19?

Perhaps you have been asking yourself the following question for a while: 'Have I got (or had) COVID-19?' You are therefore looking for a good, professionally verified COVID-19 test. In the medical world, two tests have been developed: the PCR test and the serological test for COVID-19. Your situation determines which one you should use.

 

The PCR test: have I got COVID-19 at the moment?

The best known test for COVID-19 is the PCR test (short for: Polymerase Chain Reaction). This tests whether a person is infected with the coronavirus at the time of sampling. In this COVID-19 test, a cotton swab is inserted far back in the nose and throat. The collected material is then analysed to see if coronavirus is present.

 

The serological test: have I had COVID-19?

In addition to the PCR test, there is another COVID-19 test on the market. This checks whether you have had COVID-19 in the past. This is also referred to as a serological test for COVID-19. This blood test is used to determine whether you have ever been infected with COVID-19 by looking for antibodies. In the case of our self-sampling test, you collect the blood yourself and our laboratory tests the sample for antibodies to COVID-19 (IgA and IgG).

A serological test can only be taken if you are no longer in the so-called “incubation period” of the infection. Therefore, order our self-sampling test for COVID-19 only if you have not had any symptoms for a longer period of time: at least 2-3 weeks. If this is not the case, please contact the national telephone number for advice.

Veelgestelde vragen

Why are COVID-19 antibody tests important?

Not everyone who comes into contact with the novel coronavirus develops symptoms and falls ill. And not everyone goes to their GP or contacts the national number 0800-1202 to make an appointment for a test. This makes it difficult to estimate how many people are actually ill and how many have been infected. An antibody test can give a general impression of how many people have become infected, and help to track the spread of the virus.
If you have been infected with the novel coronavirus (SARS-CoV-2), your body is likely to produce certain antibodies that you carry with you. Laboratories can detect these antibodies in the blood. This will give you an indication of whether you have already had the novel coronavirus and have therefore probably developed some form of immunity to a subsequent infection with the virus.If you have been infected with the novel coronavirus (SARS-CoV-2), your body is likely to produce certain antibodies that you carry with you. Laboratories can detect these antibodies in the blood. This will give you an indication of whether you have already had the novel coronavirus and have therefore probably developed some form of immunity to a subsequent infection with the virus.
When a person contracts a viral infection, the body puts its immune system into action. This immune system consists of various elements. One of these is the production of antibodies, referred to as the adaptive immune response. This means that the body reacts specifically to the virus and therefore needs some time to recognise the incoming virus as ‘foreign’. The other part of the immune system is the innate immune response; we all have it at birth and it always responds quickly to infection, but it is not so precise. In general, when the body encounters a virus for the first time, it also builds up a kind of memory. This means that when that person encounters the same virus for a second time, the body reacts appropriately, quickly renders the virus harmless and removes it.

In the case of the novel coronavirus, the adaptive immune response has yet to be built up and we do not yet know exactly how this adaptive immune system will behave. It may also be the case that after an infection, low antibody concentrations are sometimes measured, but that when there is a second infection with the coronavirus, these concentrations quickly rise and protect us. It is not yet clear whether this will also be the case with the novel coronavirus.

Figure: Time lag between contact with coronavirus and antibody production

If someone gets the coronavirus on Infection Day 0, then after 7-14 days the person will produce antibodies of the IgM and IgA classes. The longer-lasting antibodies of the IgG class develop later. In other words, it is very important to know what stage of a COVID-19 infection someone is in. Early in the infection, only IgA antibodies are found, a little further on both IgA and IgG antibodies can be measured and much further on only IgG antibodies. How Are You Diagnostics does not know this data. For this reason, we always provide an explanation of the various interpretations of the results. It may also be the case that How Are You Diagnostics recommends a follow-up sample after 2 - 3 weeks in order to be able to demonstrate a possible development in the antibody levels.
The COVID-19 antibody test is a self-sampling test. You can take a blood sample from your fingertip by pricking it with a sampling needle, which you can do at home at a moment that suits you. Then send the sample in the enclosed return envelope to our laboratory via a freepost number. There, an ELISA test is used to determine whether you have produced IgA and IgG antibodies. When the antibody test is ready, you will be notified via the app and you can view the report.
How Are You Diagnostics gebruikt de testen van EUROIMMUN. In Nederland is er in het voorjaar een Taskforce opgericht om diverse testen met elkaar te vergelijken en te komen tot een aanbeveling. In totaal zijn 20 laboratoria in Nederland in één of andere vorm betrokken geweest bij de validatie/verificatie van deze IgG ELISA (Enzym Linked ImmunoSorbent Assay) van EUROIMMUN en 14 laboratoria bij de IgA ELISA van EUROIMMUN. In het verslag van deze Taskforce ‘is gepubliceerd dat beide testen voor wat betreft sensitiviteit en specificiteit goed presteren bij ernstig zieke patienten vanaf 10 tot 14 dagen na de 1ste ziektedag. Aangezien dit Corona virus nieuw is en we nog niet alles weten van de antistofproductie in de groep patienten met milde klachten of asymptomatische infecties moet er nog meer onderzoek gedaan worden in grotere aantallen patienten met dergelijke minimale klachten. Belangrijk is steeds om tenminste 2 – 3 weken na het ontstaan van klachten te wachten voordat u een zelfafname doet voor de ‘Heb ik Corona gehad’ test. Bij How Are You Diagnostics maken we voor de test gebruik van een pipetteerrobot, die ingezonden patientenmonsters op anonieme basis, dus door gebruik te maken van de door u gescande barcode, verwerkt. Dat is niet nieuw; in Nederland worden dergelijke toestellen ook binnen de ziekenhuislaboratoria gebruikt. De EUROIMMUN test gebruikt 96-wells microtiterplaten, die gecoat zijn met het recombinant S1 domein van het ‘spike’-eiwit dat tot expressie is gebracht in HEK- 293 cellen. Het betreft een directe ELISA waarbij antistoffen van de patiënt binden aan dit eiwit en die vervolgens zichtbaar gemaakt door middel van IgA- of IgG geconjugeerde antistoffen. De pipetteerrobot, de Sprinter XL 240, wordt hierbij ingezet als een geautomatiseerd pipetteer- en wasstation. Uiteindelijk is de kleurintensiteit in de 96-wells plaat een maat voor de hoogte van de antistofconcentratie.

Binnen How Are You Diagnostics werken we volgens de NEN - ISO 15189. Dat maakt dat wij naast het gebruik en toepassen van literatuur gegevens, de gegevens van de leverancier ook een eigen verificatie hebben uitgevoerd binnen ons laboratorium. Daarvoor hebben we referentiemonsters getest waarvan de resultaten vooraf bekend waren. De resultaten van die verificatie waren dusdanig dat in onze handen en in onze setting de uitvoering van de ELISA kwalitatief geborgd is.

The result indicates whether you have produced IgA and/or IgG antibodies. The result can be positive or negative. Positive means that antibodies were detected in your blood; negative means that they were not. Because How Are You Diagnostics test for 2 different types of antibodies, combinations of results are also possible, i.e:
  • IgA and IgG antibodies negative
  • IgA and IgG antibodies positive
  • IgA antibodies positive and IgG antibodies negative
  • IgA antibodies negative and IgG antibodies positive
Each combination of results gives an impression of where a person is in the time lag between the actual contact with the novel coronavirus and antibody production. The table below shows the possible combinations with an explanation of their meaning. You can contact us at 0320-748701 if you have any further questions.

Table: various combinations of results with an explanation of the meaning of the result.

 

lgG antibodies                lgA antibodies                Explanation
Negative Negative No antibodies against novel coronavirus (SARS-CoV-2) have been detected in you. Based on these serological results (this is not a PCR test!), it may be that you are in the early phase of the infection and have not yet made antibodies. Our advice is: repeat this test in 2 or 3 weeks.
    If a person is still serologically negative after those 2 to 3 weeks, no antibodies against SARS-CoV-2 have been detected in the second blood sample either. This may mean that you have had no contact with the virus. But also that, despite contact with the virus, you have not made any antibodies.
Positive Positive Both lgG and lgA antibodies against SARS-CoV-2 have been detected in you. This can have several meanings. 1) You are serologically in the recovery phase of the virus infection or 2) You have had a SARS-CoV-2 infection in the (recent) past.
Positive Negative Antibodies against SARS-CoV-2 have been detected in you. This means that you had a viral infection in the past.
Negative Positive IgA antibodies against novel coronavirus (SARS-CoV-2) have been detected in you in the laboratory. We cannot draw any conclusions from this yet. If you have not had any respiratory symptoms in the last 3 weeks, this is a non-specific response by your immune system. If you have had symptoms that could fit an infection with the novel coronavirus, we advise you to repeat the test in 2 to 3 weeks. If you now have symptoms that fit a SARS-CoV-2 infection, we advise you to call 0800-1202 or contact your doctor.
If you want to know whether you have had a coronavirus infection (relatively recently or in the past), you can take the ‘have I had COVID-19’ test. You can also buy the test to see whether you have developed antibodies. Scientists do not yet know for sure whether the presence of antibodies actually protects against a new infection. Time will tell. The antibodies can be detected from 2-3 weeks after the start of the infection. It is therefore best to use the test after 14 days.
For the ‘Have I had COVID-19’ test, the laboratory needs a certain amount of blood. About 45% of each blood sample consists of blood cells, which we do not use for the test. We perform the test on the liquid part of the blood, the serum. That is why we need to receive a certain amount of blood. If it does not work with a single prick of the finger, prick another finger with the other sampling needle provided.
At How Are You Diagnostics, we have examined how long samples remain usable. For this purpose, during a hot week in June, we left some blood samples outside the refrigerator and kept them at 27°C. The results showed that the samples remain the same for at least 5 days. In other words, your blood sample will stay in good condition if the package is sent by PostNL. It should be noted, however, that it is better to collect and send it on a Monday or Tuesday so that there is no weekend in between.
It is generally assumed that if someone has IgG antibodies, he/she is protected against (immune from) a second infection with a virus. For coronavirus infections, this is not yet entirely clear and it has not yet been studied in large numbers of people. Scientific literature also refers to cellular immunity, which could be important in the defence against the novel coronavirus.
This is not certain; IgA antibodies are generally produced early in mucosal infections of the respiratory tract such as coronavirus infections. Or, for example, with an infection such as glandular fever or tonsillitis. Proof of infection with coronavirus is provided by the detection of (particles of) the RNA of coronavirus by means of a polymerase chain reaction or by the cultivation of coronavirus in laboratories specially equipped for this purpose. 
SARS-CoV-2 means Severe Acute Respiratory Syndrome coronavirus 2. That is the scientific name for the novel coronavirus. Other coronaviruses already known are Middle East Respiratory Syndrome (MERS), a coronavirus discovered in September 2012, and for example the coronaviruses 229E, OC43, NL63 and HKUI1. COVID-19 stands for Coronavirus Disease 2019; the syndrome caused by the virus. The year refers to the year the virus was first discovered in China.
Common symptoms are:
  • Cold symptoms such as rhinitis, runny nose, sneezing, sore throat
  • Cough
  • Shortness of breath
  • A high temperature or fever
  • Sudden loss of smell and/or taste (without nasal congestion)
Contact your doctor if you have a fever (temperature above 38°C) and/or if you are short of breath and are older than 70, have a chronic disease or have less resistance AND develop a fever. It is known that in many such cases, infections with the novel coronavirus are more severe.
Yes, of course you can go to your doctor with a result from How Are You Diagnostics. You can inform your doctor that we use the same test that is used in hospital laboratories.
