What are serological tests?

Serological tests assess the presence and thus the development of antibodies by our immune system, which is produced in the body in response to the virus, and give an indication of the history of the disease.

They can be used to identify people who contracted the virus unnoticed and who may have developed the disease with little or no symptoms.

Are there more types of serological tests?

There are essentially two types of serological tests: qualitative (or rapid tests) and quantitative.

In the qualitative test, a drop of blood is used to determine whether the person has produced antibodies and has accordingly come into contact with the virus. A blood sample is required for the quantitative test. This allows the specific amount of antibodies produced to be determined.

Both types of serological tests look for antibodies (immunoglobulins) IgM and IgG. In the event of infection, IgM is produced first; Over time, IgM levels drop to make way for IgG production.

If IgG is detected in the blood, it means that the infection has been present for several weeks, although the exact time is not yet known.

The scientific community is trying to understand whether the presence of IgG makes us immune to a possible second exposure to the virus. This information will also be of considerable importance from an epidemiological point of view in order to map the immunization status of the population.

What is the difference between qualitative and quantitative serological tests?

Qualitative or rapid tests are based on the technique of immunochromatography and show a positive or negative reaction in a very short time, usually within 15 minutes, without giving any information on the number of antibodies produced.

How long does it take to get the result?

15 minutes

Should the test be repeated?

According to the attending physician, the test can be repeated if there are any doubts about its interpretation or its assessment of the patient’s antibody reaction.

However, it is advisable to repeat the test after 15 days if you think you have been exposed to a possible infection during this period.

What does the test kit consist of?

The test kit contains the diagnostic device as well as antibody and antigen test strips.

Do you only offer antibodies (IgM / IgG) or also antigen tests?

Yes, we offer both tests with the same device.

Can I buy the test even if I'm not a doctor?

Yes, but we recommend having the test carried out by a specialist.

What does a false negative result mean?

Yes, but we recommend having the test carried out by a specialist.

A false negative result: the person may still be in the early stages of the disease (incubation period) and may be contagious.

Both a false negative and a false positive are risky for the infection to spread.

What are "IgM"

IgM immunoglobulins appear very early in the blood in the event of an infection. IgM is a marker for the acute phase and is tested. They are telling us, with a high probability, that we recently encountered the virus and that the infection is in the early stages.

What are "IgG"

Immunoglobulins are produced by B lymphocytes in response to an external and/or internal antigenic stimulus. In practice, they behave similarly to sentinels and are ready to alert lymphocytes, which are activated to produce a very high number of antibodies (up to 2,000 per second) as soon as they come into contact with the attacker.

Within the immune system, immunoglobulins form the main component of humoral immunity, therefore they have the function of neutralizing foreign substances, recognizing any antigenic determinant as a target, and making them easily identifiable for phagocytes and cytotoxic cells.

What is immunofluorescence?

Immunofluorescence is a microbiological and immunological technique, the purpose of which is to identify whether certain antigens and bacterial or viral antibodies are present in a given sample.

Their presence can be detected using a dye that fluoresces the antibody being sought. These elements are thus visible when the sample is observed with a confocal or a fluorescence microscope.

Are the product and the test certified?

Yes, they are certified by TÜV SÜD Product Service. TÜV SÜD is recognized worldwide as one of the leading independent bodies for product certification and has extensive experience with all types of medical devices. They are also CE marked and therefore comply with the relevant EU directives.

How many years of guarantee is there and how can the test kit be returned in the event of a malfunction?

The machine supplied is guaranteed for 2 years from the date of purchase. The guarantee does not apply to parts that are subject to normal wear and tear, as well as to the damage caused by knocks, falls, improper use, manipulation, or carelessness in use by the customer.

If you discover defects or anomalies, contact us via info@lifetest.ch and describe the malfunction to us. The return will then be made and a replacement machine will be delivered.
