( NEXSTAR)– Sore throat, runny nose and a headache– the signs might imply your body is hammering out a cold, the flu or a COVID infection. You may not have had access to a COVID-19 test, or perhaps your signs disappeared before you had the opportunity. Theres also the possibility you evaluated prematurely in the infection, so you got an incorrect unfavorable.
Exists a method to inform if that illness you had a month back, or perhaps last year, was COVID or something else?
The method to tell whether you had COVID-19 in the past is by utilizing an antibody, or serology, screening. When your body is exposed to the virus, it develops antibodies to combat it off. These tests try to find those antibodies to validate previous infection.

It can take weeks for someone to establish antibodies after infection, the CDC stated. If you believe youve been exposed to the virus recently, you ought to look for a viral test, like an antigen or PCR test, instead.

Both the CDC and the Food and Drug Administration have actually said they do not suggest antibody testing as a method to identify if youre protected from the virus.
There are 2 types of antibodies your body produces: antibodies versus the spike protein (S), which are produced by vaccination, and antibodies against the nucleocapsid (N), which are created by prior infection.
If a test finds you have the N-type antibodies, it shows previous infection, a Centers for Disease Control spokesperson explained to Nexstar. If the test discovers you have S-type antibodies and do not have N-type antibodies, then it suggests youve been immunized but havent been contaminated.
” CDC is examining antibody security and for how long defense from antibodies may last,” the firm states. “Cases of reinfection and infection after vaccination have been reported, however remain unusual. However getting vaccinated, even if you have actually currently had COVID-19, can assist your body make more of these antibodies.”.
