Hi
No it is not accurate because antibodies appear later so you have 2 options , no1 is to repeat after 3 month of initial test, no2 is to do antigen test
Good Luck
hi,
its 99% sensitive test. but to confirm,you need to get a pcrrna antigen test.
window period is 6 months post-exposure.
so repeat the test after 6 months from your date of exposure.
thanks
It is a highly sensitive but not usually Indicator of infection or else as the production of antibodies takes from 3-6 months to show ..
So you need to do an antigen test.
Or wait 6 months to repeat this one.
