Covid-19 Tests

COVID-19 tests

Introduction

First, serological tests provide us with rapid results, but they lack reliability. Serological tests are responsible for measuring the amount of antibodies or proteins found in the blood when the body responds to a specific infection as in this case: COVID-19. 

Developing

In other words, the test identifies the immune response that the body has in front of the infection caused by the virus, instead of detecting the virus itself, but in an early phase of infection, when the organism is still identifying and determiningAggressive agents may not detect antibodies. This decreases the effectiveness of the test for the accurate diagnosis towards COVID-19 and therefore should not be used as the only means to diagnose an infection by COVID-19. 

Sofía Flores, a professor at the University of Sheffield in England, mentions that serological tests have considerable disadvantages such as: to those patients to whom serological tests are applied require at least one of the symptoms of infection, development indicationFrom antibodies product of virus infection, this should be taken into account because although it is known in SARS-COV2 infection there is an incubation period of at least one week, a period in which the patient is asymptomatic, butIt can infect, what would already be unnecessary to perform an antibody test because it no longer works in the early detection of infection. Likewise Eleanor Riley, professor at the University of Edinburgh, explains that it is not interested how many times one of these serological tests is carried out, no very low levels of antibodies are detected.

As well as home pregnancy tests are not accurate, serological tests should never be used as definitive indicators, someone has had the virus, referred to a positive result, it should be found as a warning for more tests and confirmation, and a resultNegative does not suppose the person has never had the virus. On the other hand, Ernesto Bustamante a Peruvian scientist recognized in the field of molecular biology, in an interview he spoke on the subject and said the intention of the government is good, but the correct rapid test is not being purchased. This is not going to make a timely detection, but a late and that is bad for the vulnerable population because they have no capacity to produce antibodies and their immune response will be slow and will make it impossible to have positivity at a convenient time. 

conclusion

In that sense, Bustamante said that the vulnerable population would be the most affected. Scientists still do not know what the ideal response of the Immune System against COVID-19 is, because of this, the precision of the tests that detect antibodies is still under review, having a false negative brings dangerous consequences for the person who is going through symptomsvery serious, due to the timely care response and the possibility of infection intensifies. People are interested in these tests because they want certainty and security The problem with serological tests is that they cannot give them that.
