The purpose of screening is early diagnosis and treatment. Screening tests are usually administered to people without current symptoms, but who may be at high risk for certain diseases or conditions.
There are no screening guidelines for cold sores.
A simple antibody blood test can show if you have been exposed to the herpes virus in the past. If you test positive, it means you could get a cold sore in the future. However, since almost everyone tests positive for herpes simplex type 1, this test is not very useful for screening purposes.
