In the middle of a pandemic Covid-19 many people are competing to improve body immunity maximally so as not to be infected with Covid-19 and other diseases. One way is to get the Covid-19 vaccine.
Pathology specialist from Siloam Hospitals Purwakarta, dr Adrian Suhendra, Sp.PK. said, there is a quantitative serological test which is a medical method through taking blood samples that serves to identify pathogens in the human body.
“The purpose of this test is to find out and see a person’s immune response or antibodies from someone who has received the Covid-19 vaccine injection,” he said, Sunday (7/3/2021).
According to Doctor Adrian, quantitative serology tests are carried out in a special serology laboratory which aims to read the results of the examination quantitatively. This is the number of antibody titres present in the blood.
“This test is different from the previous rapid serological test, the qualitative method, which shows whether the test results are reactive or non-reactive. The point is that the quantitative serology method functions to check the body’s immunity after vaccination,” said Adrian.
Serological quantitative tests use immunoassays to determine the quantitative value of antibody titres against the Covid-19 Spike-Receptor Binding Domain (S-RBD) protein in human blood. This method will help give a person’s antibody value results accurately so that patients can find out how their body’s immune response is to Covid-19.
Serological quantitative tests are a type of immunological test that evaluates the Covid-19 antibody titer in a person’s body, both post-Covid-19 vaccine and conditions after exposure to Covid-19. Because of that, the quantitative serology test is different from the serological qualitative test in general.
The serological qualitative test aims to screen for Covid-19, while the serological quantitative test aims to determine the antibody titer of a person against Covid-19, which is shown in u / mL units.
In addition, quantitative antibody tests are also useful in assessing a person’s humoral immune response, namely antibodies to Covid-19, both in Covid-19 survivors and in individual vaccine recipients. In the process, the collection of serological quantitative test samples taken from venous blood with the examination processing time is about 120 minutes.
Well, this quantitative serology test has three uses, namely:
1. For those who have been vaccinated against Covid-19, can find out whether the body already has immunity or does not have Covid 19 antibodies.
2. Covid-19 survivors can find out whether the serology can protect themselves or can still be exposed again.
3. Convascular plasma therapy, namely as a donor (a person who has recovered from Covid-19 and has tested negative) for Covid-19 sufferers / patients.
