Herpes Zoster Diagnosis & Tests
Diagnosis is suspected based on the appearance of the skin lesions, and strengthened by a prior history of chickenpox or shingles. It can be confused with herpes simplex.
Tests are rarely necessary, but may include:
- Viral culture of skin lesion
- Tzanck test of skin lesion
- Complete blood count (CBC) may show elevated WBC (a nonspecific sign of infection)
- Specific antibody (immunoglobulin) measurement demonstrates elevation of varicella antibodies
