About 1.3 million Americans have been tested for the Corona virus, but with the development of antibody tests, doctors can now finally measure the body's immune response to Covid-19 and determine the body's ability to form immunity against future infections.

Brandan Robertson, pastor at a church in San Diego, USA, who underwent a test of this kind and found that he had the disease, then managed to escape from it. Antibody test if his body would later have immunity, and how he returned to his normal life wearing the mask:

■ How did it go to the test? Where did you go?

■■ I was in Europe in February when the Coruna virus began to spread. Weeks after returning home, I felt hot and short of breath and started coughing. I called my doctor, who informed me that there were not many tests available, and he advised me to stay at home for two weeks to see if the symptoms would ease. The symptoms were similar to the symptoms of severe cold during this period, but they faded and returned to my daily life and I was not sure whether or not I had Covid-19.

Then I received an email informing me of the availability of antibody tests. The next day I went to the center to take the test by taking a blood sample with a finger prick, and after 10 minutes the nurse told me that I had the virus.

■ How did the nurse describe your HIV infection? Have you become immune to infection again?

■■ the test has three results, i will explain it simply. The first is negative, which means no injury. The second indicates that you currently have it and the presence of antibodies in your body that are resistant to the disease, while the third means that you are infected with the virus with antibodies indicating your recovery from it. The nurse said that the test is not entirely accurate, but the results are largely acceptable. She pointed to the lack of scientific evidence to suggest the development of immunity to the virus, but I may be immune for the most part. She advised me to go about my daily life, but to wear masks.

■ Did you change your lifestyle after knowing the result?

■■ I increased my confidence after knowing that I was infected with HIV and how my body reacted to it. I do not hide my fear of being infected again, and it certainly would not have been as bad as the media described if it happened.

■ If these tests become available to everyone, will this make a difference in society? Do you think that the behavior of the injured will change?

■■ The test revealed to me that the number of injured exceeds the mentioned numbers. We would not have had the test while we were injured and would not have known without the antibody test. In addition, the test cost me $ 50 with insurance, which makes it difficult for many. Returning to normalcy requires knowing all of these things and studying whether or not immune formation is correct for people with HIV.

■ What do you say to those who stay in their homes and doubts about HIV infection?

■■ I went out for a walk and this helped me a lot in improving my mood. Who would have expected the world to stop for several months? In the midst of this ordeal, I was urging community members to review themselves. I hope to see people again and to acquire new habits. And now the test "Covid-19" is more available than before. If you are ill, go to undergo it, cut suspicion of certainty and help reduce injuries if you are injured.

I used to go hiking and this helped me a lot to improve my mood.

I have hope to see people again and to acquire new habits.
