Coronavirus test in our clinic

In order to detect an acute infection by the corona virus (medical name SARS-Cov-2), a PCR test (Polymerase Chain Reaction) must be performed.

On the other hand, a subsided infection is confirmed by antibody detection (SARS-Cov-2 IgG antibody).

Detection of an acute Covid-19 infection:

In cooperation with the SYNLAB Laboratory in Madrid, we are now able to detect an acute Covid-19 infection by direct pathogen detection. For this purpose, a swab of the nasal and/or pharyngeal mucosa is performed in our clinic. The test is evaluated within 24-48 hours and can be accessed directly in the laboratory via a code. The laboratory will provide you with the result in Spanish and English. In addition, you will receive a medical certificate of the test result in English, German, Spanish and French.

What does a positive PCR test mean?

If you test positive you are a virus carrier and can infect other people. However, this does not mean that you will show or develop symptoms, as the majority of SARS Cov-2 infections are asymptomatic.

 If you have been tested positive you should immediately go into quarantine and make an appointment in our practice to discuss the further course of the disease (phone 91 5643887).

 We are obliged to report positive cases to the Spanish health authorities (Consejería de Sanidad).

What does a negative PCR test mean?

On the day the sample was taken, no viruses were detectable in your nasopharynx. This means that you were not contagious to other people at that time. However, you could have been infected with Covid-19 at an earlier time. It is also possible that you were infected shortly before the sample was taken and the test could not yet react positively due to the low virus concentration. Of course an infection is possible at any time after the test has been performed.

How can we detect an expired Covid-19 infection?

In cooperation with the Laboratory SYNLAB we can perform a highly specific test for antibodies against corona viruses (SARS-Cov-2-Ak). The test is performed by taking a blood sample and allows a statement about an expired infection with the corona virus SARS-CoV-2. If the human body comes into contact with the virus, it forms antibodies (immunoglobulins). These are detectable in the blood, regardless of whether the person is ill or not.

What does a positive IgG test mean?

If your result is positive, you have passed the infection. According to current scientific knowledge, you can be considered 'immune' to the SARS-CoV-2 virus. It is not yet known how long the immunity will last. However, at this point in time (and in the current state of knowledge), such a result is of importance for you in various ways:

  1. You are actually protected in a natural way against a new infection.
  2. From an epidemiological point of view, you are considered to have recovered from Covid-19 and you are no longer contagious.
  3. We recommend that your close contacts (family members, colleagues, etc.) should also be tested, regardless of whether they have had symptoms or not.

What does a negative IgG test mean?

If the test is 'negative', the coronavirus SARS-CoV-2 has not yet left any 'traces' on you. Either you have not yet had contact with this virus or you are in the early stages of infection and your body has not yet produced any antibodies.

This means:

  1. If you have typical symptoms of the disease, it should be decided in consultation with us whether a PCR test is useful or whether a new antibody test should be repeated after some time.
  2. If no antibodies are (yet) detectable, you are susceptible to Covid-19 disease. You must continue to protect yourself and others (keep your distance, use a face mask, wash your hands regularly).   


There are still many unanswered questions in the current SARS-CoV-2 pandemic, especially regarding the Covid-19 disease caused by the virus and its subsequent damage. All the information we provide here is based on the current state of medical knowledge. With the great dynamics in all areas of research and therapy, new findings are being made every day. We make every effort to communicate them to our patients in a timely manner.
