Available coronavirus tests- what is the difference?

Kelen Hopital is open weekdays and weekends!

If you have symptomps or you are in quarantine, on-the-spot PCR tests (performed at your current location) are available on request. In this case please contact with us : + 36 30 656 5969 or write an e-mail kelen@kelen.hu.  Official tests result are available in different languages. We do not refund for payments of cancelled testing!

 

1, Detection of coronavirus-SARS-CoV2 by PCR test (mouth and nasopharynx)

You can find a detailed description of this screening HERE – please read it carefully

The result will be sent electronically in 24 hours. With this test, we can detect the virus in the cells taken from the mucous membranes of the pharynx and nose. To do this, a swabstick is pressed against the pharyngeal wall and the back of the nasal passage, and a sample is taken from here.

PCR can be used for virus identification, after the day of infection:

1. after the initial days of the incubation period (1-14 days, in average 5 days)
2. during the symptomatic period
3. after the termination of the disease, that is, up to two weeks after becoming asymptomatic– to the best of our knowledge today –.

2, Detection of coronavirus antigen, Ag rapid test (nasopharynx)

The Covid-19 Ag rapid antigen test detects the antigen of the infecting coronavirus. A rapid test method to detect the presence of viral protein in the early stages of the disease within 20 minutes if the suspected at least 4 but not more than 14 days have passed since encountering the source of infection and have had symptoms characteristic of Covid-19 for at least 4 days (dry cough, fever, shortness of breath, loss of smell, taste disturbance).

3, CORONAVIRUS RAPID TEST – antibody test

This test is suitable for screening patients who have already been infected, but will detect the disease even if it is still present, provided that at least 10-14 days have elapsed since the onset of the infection (encounter with a known infected person or a known onset of the disease).

A simpler, faster and more cost-effective way to detect coronavirus infection is to detect the body’s protective molecules, antibodies (also known as antibodies) produced after the infection.

After infection, approx. 2 weeks after the early antibody, IgM, about 3 weeks after infection, the late antibody, IgG, is present in the blood and can be detected by tests. The amount of specific IgM antibody produced against the virus gradually decreases over weeks and then disappears from the blood, and IgG is likely to remain there permanently, and to the best of our knowledge, this may provide protection against infection, presumably for 1 to 3 years. We do not yet know how long this acquired immunity can last. 1-3 years is an estimate based on experience with SARS-COV-2-related coronaviruses.

4, ELISA test 

The ELISA test can reliably, with high safety and sensitivity detect the antibody produced by the body against to the SARS-CoV-2 virus (IgA IgM or IgG), thus SARS-CoV-2 virus infection can be proved. This type of test is performed in a microbiological laboratory using a venous blood sample.

5, Detection of coronavirus antibody, Centaur XPT (venous blood)

Based on the latest serological tests, we are able to determine whether patients who have undergone COVID-19 infections, are present with antibodies that are likely to provide protection against the disease. Venous blood sample taken from patients can be used to show that patients have developed an antibody (total immunoglobulin) that neutralizes the S protein of the SARS-CoV2 virus, that is responsible for the virus entering the cell. The test can show with great certainty whether antibodies are present in the person’s body after the virus has been infected.

What type of test is accepted for border crossing?

It depends on the country, which test is accepted, how many tests are needed within how many days. It is important to always check the regulations in force at the time before of the planned trip!

Where can you find information?

Embassy / Consulate of the given country -https://konzuliszolgalat.kormany.hu/utazasi-tanacs
We recommend that you always plan your trip based on written information from an official body.
In our own experience, 1 negative PCR result is most often required, but there are cases where a rapid test result is also sufficient.

Quarantined, what kind of examination is the Department of Public Health asking to terminate it?

A negative PCR result is usually requested, but please check with the Public Health Department of the Government Office responsible for the address of the quarantine for exact expectations and the procedure.

Can I leave the quarantine or request an onsite sampling to complete the test?

In our experience, the current practice is not uniform:
– there are those who cannot leave the quarantine, so we can carry out the necessary
sampling at your residence
– there is a person who can leave the quarantine for the purpose of the examination
with an individual route permit, but cannot use public transport and must return to the
quarantine immediately

Please contact the Public Health Department of the Government Office responsible for the quarantine address for exact expectations and the procedure.
