Herpes Simplex Virus DFA with Reflex to Herpes Simplex Virus Culture
Copy Utility
A rapid diagnostic test with culture backup for negative DFA results. Test may be helpful in identifying acute herpes simplex virus (HSV) infection in active lesions (eg, vesicles, ulcers, inflammation of mucous membranes). Molecular testing is generally preferred (refer to Herpes Simplex Virus by PCR (0060041)).

If DFA is negative or inadequate, then a HSV culture will be added. Additional charges apply.
Sensitivity of DFA methodology is dependent upon adequacy of the specimen. If specimen contains fewer than 20 cells, then the DFA result will be reported as "inadequate."
