Depending upon the index value of your antibody test, this may or may not be a true positive. There are lots of false positives on this test. I recommend obtaining a confirmatory test since you’ve had no symptoms. The best is the western blot from the University of Washington. I can help you with that if you wish. ‘
If you have an accurate test, you are infected and can transmit the virus when you do and when you don’t have symptoms. It would be best for you to know whether you have this or not.
