According to Forbes News and CNBC website reports, WHO experts said that the new coronavirus serum test (also called antibody test) can indeed show whether a person has been infected with the virus in the past, but there is no evidence that the test can prove whether a person has Immunity, or there is no longer any risk of reinfection.

Dr. Maria van Kokhov of the WHO said: “There is currently no evidence to show whether the use of serum testing can prove whether a person is immunized or immune from reinfection.” Mike, Executive Director of the WHO Emergency Plan Dr. Ryan mentioned that scientists are still determining how long the antibodies may provide protection for people infected with the new coronavirus. “No one can be sure that people with antibodies will be fully protected from getting sick or exposed to the virus again. In addition, some tests have sensitivity issues and they may give false-negative results. . “

The US media pointed out that serum testing or antibody testing can indicate whether a person has had new coronavirus pneumonia in the past and whether it is asymptomatic or a recovered patient. Earlier this week, WHO officials said that not all patients with new coronavirus pneumonia have antibodies that can resist secondary infections, which makes people worry that patients may not develop immunity after recovery. “Regarding the problem of reinfection after recovery, I don’t think we have come to an answer yet. This is an unknown.”
