If they do a swab test to check for herpes and it comes back negative does this mean that the virus isnt on your skin anymore even if you have a sore still. I don't understand how you could have a sore and the test could come back negative even if it was herpes.
Lesion cultures are most accurate if done within 24-48 hours of the appearance of sores. After that the risk of a false negative rises very quickly.
Regular viral lesion cultures rely on getting enough active virus on the swab initially as well as it surviving the trip to the lab and then also having to actually grow in the lab. Lots of room for false negatives with all of that unfortunately.
