Instructions
Lesion/mouth/ocular –
1. Collect lesion and dermal specimen using the culture swab with plastic shaft.
2. Carefully insert swab into site to be tested and roll swab 5 times.
3. Place swab in vial of medium.
4. Break swab shaft at score marking, replace cap tightly.
5. Label tube with patient name, MRN or DOB, and appropriately document source, collection date/time and collector.
Genital
1. Collect specimen from cervix, penis, rectum, urethra, vagina, or other genital site using a culture swab with plastic shaft.
2. Carefully insert swab into site to be tested and roll swab 5 times.
3. Place swab in vial of medium.
4. Break swab shaft at score marking, replace cap tightly.
5. Label tube with patient's name, MRN or DOB, and appropriately document source, collection date/time and collector.

VZV Amplified Probe- Not Detected
Clinical Significance
An in vitro diagnostic test for the qualitative detection of varicella-zoster infection in cutaneous or mucocutaneous lesion (dermal lesions, mouth lesions and genital lesions, etc) samples from symptomatic patients.
The amplification and detection of target sequences is performed using isothermal Helicase-Dependent Amplification (HDA) in the presence of target-specific fluorescence probes.
