Sanger Sequencing

Test Usage

The test is designed to detect and characterize Acyclovir drug resistance associated with specific mutations found in the Thymidine Kinase (UL23) gene of both HSV Type 1 and HSV Type 2. These mutations can lead to reduced or absent response to Acyclovir, a commonly used antiviral treatment.
