WHAT IS AN ANTIBODY, HOW IS TEST PERFORMED?
Antibodies are proteins that help the immune system identify and eliminate threats. It also helps the body protect against the same threat of possible future infections. For this reason, during the pandemic period, antibodies have a separate importance. So, how is the antibody test performed? Here’s the answer to that very curious question…
After infection due to the SARS-CoV-2 virus or after vaccination, our body basically develops antibodies against two antigenic structures. These antigenic structures are Spike protein and N protein. The Spike protein is involved in the entry of the virus into the cell, while the N protein forms the cell wall of the virus. Antibodies fight the SARS-CoV-2 virus by recognizing these proteins.

WHAT IS AN ANTIBODY?
Currently, two methods are used to diagnose COVID-19 disease: antibody testing and PCR testing in Turkey. As with all foreign substances, when the virus enters the body, it encounters our immune system and tries to destroy it from the body. In this struggle of the body, proteins called “antibodies” produced against the virus play a very important role. An antibody test is a test in which these antibodies are detected in the body specific to the virus. Antibodies can reach detectable levels within 1-3 weeks.
An antibody refers to a substance produced by the immune system in response to an antigen that enters a person’s body. It is also called immunoglobulin. Antibody testing is performed to determine a person’s immune status to the disease. Now one of the most answered questions in today’s pandemic is “how is an antibody test performed in Antalya and Istanbul? let’s get straight to the topic.

HOW IS ANTIBODY TESTING PERFORMED?
The results with the highest sensitivity and specificity in the antibody test are obtained from the tests studied by the ELISA method. In Tests known as rapid testing, which can also be performed personally by taking fingertip blood, the rates of false positivity and negativity are high. 5-10 ml of blood is enough for the Test. The Test results are revealed within 4 hours.

WHEN DOES THE ANTIBODY FORM?
Antibodies to the virus 3 to 7 after the onset of symptoms. they begin to appear from day to day. Antibodies to the N protein begin to decrease earlier, usually in the first month. Among the current current information is that antibodies that develop against the Spike protein can be detected in the blood for at least 1 year. The earliest time for follow-up of antibody levels after vaccination, 15 days after vaccination, the most ideal time is 28 days after vaccination. 6-8 months after vaccination, the continuity of the antibody level can be controlled.
