Exams and Tests
A doctor will base a diagnosis on information you provide and on physical examination. The characteristic appearance of the herpes sores leaves little doubt. Further testing is usually not necessary.
If you require a definitive diagnosis, for instance, if your infection involves other organ systems, the doctor may conduct laboratory tests.
- A sample from the sores to identify the virus
- A staining test called the Tzanck smear
- Antigen and antibody studies
- Blood sampling for antibody studies
Oral Herpes Treatment Self-Care at Home

- Drink plenty of fluids to prevent dehydration.
Treatment includes medication for fever and taking plenty of fluids.
- A topical anesthetic such as viscous lidocaine (Dilocaine, Nervocaine, Xylocaine, Zilactin-L) may be prescribed to relieve pain.
