Thank you very much for your post and welcome to our forum.
As you did not mention the type of exposure, it is not possible to estimate the risk and assess the reliability of the test.
However a negative PCR RNA test after 10 days has a very high level of reliability, over 99%. Moreover you had it repeated after 29 days, and the combination of these, together with the negative antibody test, we could possibly consider it conclusive, as in the case of infection, the virus would have been detected. On the other hand, current guidelines do not consider the PCR RNA test as diagnostic and fully conclusive and would always recommend a repeat test (either a Duo after 4 weeks, or an antibody test after 12 weeks). Guidelines tend to be very cautious and conservative though, and in my experience, you should not worry. Antibody tests would detect antibodies in most cases already after six weeks of a possible exposure.
Possible exposure was protected vaginal and protected oral with csw.
get a grip, this site is for people with exposures
Does seretide,pulmicort for asthma affect the combo test results @ 31 days after exposure,,,,
