COVID-19 TESTS AND VACCINES

COVID-19 TESTS AND VACCINES

Different tests and vaccines of Covid-19 have been discovered, but even more is being sought. The cure has not been found, but there are vaccines that the WHO (World Health Organization) does not allow.

TESTS:

  • PCR: This is a test that detects the SARS-CoV-2 virus in respiratory samples from people with symptoms or asymptomatic (who have passed Covid-19). To do this, you need a mucous sample from the nose and / or throat, which the health professional extracts with the help of a stick. The tests are analyzed in the specialized laboratory and the results can take from 24 to 72 hours.
  • FAST ANTIGENIC TEST: This is a test that detects virus proteins. It identifies people who are suffering from a SARS-CoV-2 infection, especially in the first five days of presenting symptoms. It is done with a sample of the nose and throat, which the health professional extracts with the help of a stick. Generally, the results are analyzed at the sample collection site. Results take about 20 minutes.
  • SEROLOGICAL TEST: This is a test to detect antibodies against the SARS-CoV-2 virus in the blood. It allows to determine the immune status of the person against the virus. It has a fundamentally epidemiological utility in knowing the immune status of the population. In certain circumstances, it may be a complement to the interpretation of PCR results. It is done with a blood sample, which the healthcare professional draws with a syringe. The results can take from a few minutes to a few hours, depending on the technique used, and should always be interpreted by the medical professional who prescribed the test.

TEST RESULTS:

PCR: A positive result means that the presence of the virus has been detected. In this case, the healthcare professional should indicate what needs to be done.

Rapid antigen test: A positive result means that you are a carrier of the virus and have the ability to transmit the infection. In this case, the healthcare professional should indicate what needs to be done.

Serological test: A positive result means that there has been contact at some point with the COVID-19 virus and that the body has generated antibodies to defend itself against the disease. The interpretation of the serological results must be performed by a healthcare professional, and until the healthcare professional contacts to interpret the results, it is necessary to follow all the established measures for the prevention and control of the infection.

In the event of a negative result, the healthcare professional must assess whether it should be confirmed by performing a second PCR depending on the patient.
